成都交子人行桥面公园景观设计

项目位于成都市高新区金融城片区，是一座横跨锦江之上的全人行盖板式绿化桥，是链接东、西交子公园绿地的重要枢纽。桥面宽约120米、长约 1100米，面积约12300平方米，再加上两侧链接区域的绿地公园景观更新，共约为38000平方米。西起交子公园（西区），由西向东依次跨越科华南路（红星路南延线）、锦江绿道、锦江、国华街，止于交子公园（东区）。桥梁共分为跨河主桥段、跨线桥（跨科华南路）、引桥（坡道）及梯道三部分。共设置4处螺旋形梯道及电梯与市政道路接驳，主桥东岸设置1处梯道及坡道与锦江绿道接驳。

The project is located in the Financial City area of Chengdu High-Tech Zone. It is a pedestrian-only, deck-type green bridge spanning the Jinjiang River, serving as a crucial link between the green spaces of East and West Jiaozi Parks. The bridge has a width of approximately 120 meters and a length of about 1100 meters, covering an area of 12,300 square meters. Combined with the landscape renewal of the connected green park areas on both sides, the total project area reaches approximately 38,000 square meters. Starting from Jiaozi Park (West District) in the west, the bridge crosses Kehua South Road (a southern extension of Hongxing Road), the Jinjiang Greenway, Jinjiang River, and Guohua Street, terminating at Jiaozi Park (East District).The bridge is divided into three main sections: the river-crossing main bridge, the overpass (crossing Kehua South Road), and the access ramps and stairways. Four spiral stairways with elevators connect to the municipal roads, while the eastern end of the main bridge features one additional stairway and ramp connecting to the Jinjiang Greenway.

我们作为方案深化及施工图设计单位，在交子桥整体规划、设计的内容前提下，重新组织与地面绿地系统的衔接、恢复滨河绿道与桥面公园的交互关系，同时在桥面公园整体极限结构的限制下呈现桥面绿地系统的落地。实现了东西绿地公园、南北立体游逛系统的有效链接。与滨河绿道系统形成纵横交织的公共景观开放空间，提供一处可游玩可感受可亲近自然的市民空间。

As the unit responsible for the scheme development and construction drawing design, we reorganized the integration with the ground green space system and restored the interaction between the riverside greenway and the bridge park, based on the overall planning and design of the Jiazi Bridge. At the same time, we presented the implementation of the bridge green space system within the structural limitations of the bridge park's overall extreme design. This achieved an effective connection between the east-west green space parks and the north-south multi-dimensional strolling system. Together with the riverside greenway system, we created an interconnected public landscape open space, offering a recreational and immersive natural environment for the public.

在这一前提下，桥梁设计团队提出了盖板式桥面公园的概念，保证了在桥面通行的基本功能下，还能最大程度链接东西公园的绿地系统，让人行走在桥面上，也是在公园的整体系统中。并提出单一的板式桥梁到灵动的莲叶组合式桥梁的思路，结构形式从自然中莲叶生长的茎杆中汲取灵感，创造出10大空间节点，增加桥面游逛内容的丰富度，实现绿色开放、全时共享的桥上花园。

Based on this premise, the bridge design team proposed the concept of a slab-type bridge park, which ensures that, while maintaining the basic functionality of the bridge for traffic, it also maximizes the integration of the east-west park green space system. Walking on the bridge is akin to being within the overall park system. Additionally, the team introduced the idea of transitioning from a simple slab bridge to a dynamic lotus leaf-inspired composite bridge, drawing structural inspiration from the stems of lotus plants in nature. This design created 10 major spatial nodes, enhancing the richness of the bridge’s strolling experience and realizing a green, open, and fully shared garden on the bridge.

深化设计之初，桥面公园的一些基础信息

Fundamental Information at the Outset of Detailed Bridge Park Design

由于河道管理对于桥墩数量及直径的限制，对桥面结构计算就提出了较高要求。在盖板部分的桥梁深化设计时，结构设计单位为了解决这一难题，经过数轮论证及计算，通过四根桥墩柱撑起了整个桥面，最终形成桥下净空8.8米，桥墩柱直径2.5米，桥墩净距67.5米，既保证桥下通航的前提，也使得整个桥梁系统看起来像是漂浮在锦江上的“绿色浮岛”，轻盈且科幻。

Due to the restrictions imposed by river management on the number and diameter of bridge piers, the structural design of the bridge deck faced high demands. During the detailed design of the slab section, the structural design team addressed this challenge through multiple rounds of discussion and calculations. Ultimately, they supported the entire bridge deck with four bridge piers, resulting in a clear height of 8.8 meters under the bridge, a pier diameter of 2.5 meters, and a pier spacing of 67.5 meters. This solution not only ensures the clearance required for navigation beneath the bridge but also gives the entire bridge system the appearance of a "green floating island" hovering on the Jinjiang River—light and futuristic.

四根结构柱完成了对桥面的支撑，桥面的荷载预留十分有限。主桥圆盘中间半径4m范围内拟进行植树，按照等效覆土1.5m进行考虑，即圆盘中心半径4m范围内按照27 kN/m2进行计算。圆盘靠近人行道4m范围内考虑按4m等间距环向植树，按照150kN集中荷载进行计算；桥梁的钢结构板到完成面预留5cm厚度，需要同时考虑所有桥面系统的给排水、强弱电、泛光系统、专项系统的管线等，还要考虑抗拉抗变形的高性能地面铺装。这些内容需要一个集成的整体统筹考虑方能完整得以实现。

The ultra-slim structural columns effectively support the bridge deck, but the load-bearing capacity of the deck remains highly constrained. Within a 4-meter radius at the center of the main circular platform, tree planting is planned, with calculations based on an equivalent soil depth of 1.5 meters and a load of 27 kN/m². In the 4-meter range adjacent to the pedestrian walkway, evenly spaced circular tree planting at 4-meter intervals is planned, calculated as a 150 kN concentrated load. The steel structure of the bridge provides a 5 cm thickness reserved for the final deck surface, which must accommodate the integration of all bridge systems, including drainage, power and lighting systems, and specialized pipelines. Additionally, it requires a high-performance pavement that resists tension and deformation. Achieving this necessitates comprehensive, integrated planning to ensure seamless execution.

明确架构 梳理专项实施必要条件及各关联衔接项

Clear Structure: Establishing Key Implementation Conditions and Interconnected Elements

在深化工作之初，我们讨论、梳理了桥面几个节点的主题内容，需要从材料、生产厂家、实施路径及条件，并跟桥体本身的结构特性、材料特性相结合，反向推导其之间的组合关系、管网逻辑、形体关系及材质感受等。项目的难点在于多处技术综合应用在国内当属首例，在前期的统筹协调及设计安排上面临较大难题。

At the outset of the design development, we discussed and organized the thematic content of several key nodes on the bridge deck. This required consideration of materials, manufacturers, implementation paths, and conditions, while also integrating these factors with the structural characteristics and material properties of the bridge itself. We then worked backwards to deduce the relationships between these elements, including their combinations, network logic, spatial configurations, and material sensations. The challenge of the project lies in the pioneering application of multiple technical integrations, which are a first in the country. This posed significant difficulties in the early-stage coordination and design arrangements.

▲工作初期对各专项节点梳理  

Early Work: Mapping Out Key Nodes for Design

在与多专业的多家供应商、顾问团队讨论后，最终确定多节点的组合关系。明确了设计深化工作的组成顺序。例如，需要兼顾多景观节点的供水，在给水方案上，如何到达桥面就有多条路径，但需要协同各专业一起讨论，得出初步实施方案，再经由业主方、物业管理等给出具体操作意见，再到落地的方案和技术图纸。给水达到桥面，需要再协同桥梁设计，尽量实现管线的隐藏，桥面因为面层厚度无法通过，需要从墩柱侧面寻找路径穿过，且避免能量损耗保证加压水景的功效，管道路径保证在120米以内，再从桥板面有限开孔区域升至桥面景观节点处… …诸如此类问题，需要集中的在深化设计的全过程与各专业紧密协同，保证最终呈现的终极效果。

After discussions with multiple suppliers and consultant teams across various disciplines, the combination relationships of the various nodes were ultimately determined. This led to the establishment of the sequence for design detailing. For instance, considering the water supply needs of various landscape nodes, multiple potential pathways for delivering water to the bridge deck were explored. These pathways required interdisciplinary coordination to develop an initial implementation plan, which was further refined based on input from stakeholders such as the project owner and property management. The finalized implementation plan and technical drawings were derived through this iterative process.Delivering water to the bridge deck necessitated additional coordination with bridge designers to hide pipelines wherever possible. Since the surface layer thickness of the bridge could not accommodate pipes, alternative routes were identified along the sides of the piers to avoid energy loss and ensure the efficiency of pressurized water features. Pipeline pathways were designed to remain within a 120-meter limit, ascending through limited perforations on the bridge deck to reach designated landscape nodes. Challenges of this nature required continuous interdisciplinary collaboration throughout the detailed design process to achieve the optimal final presentation.

桥面廊架的实施落地

Implementation of Bridge Deck Colonnades

人行桥在规划之初，为解决在桥面公园休憩遮风避雨的功能，设置了能提供更多人群使用的大挑檐廊架。并因为人群的聚集，为将来实施的运营空间提供可能性，形成多种复合空间的使用功能。

In the initial planning phase, large eave-like colonnades were incorporated into the bridge deck park design to provide shelter for pedestrians, enabling rest while protecting against wind and rain. Recognizing the potential for gathering crowds, these colonnades were also designed to accommodate future operational needs, offering multifunctional and adaptable spaces for various uses.

但因为本身处于河道中，抗震、风力、结构荷载等诸多因素影响着大跨度的挑檐的结构实验。其中最大跨度的一号廊架，挑檐宽度达16米，并且要实现极致轻薄的边缘檐口效果，我们在结构形式上尝试过无数次，最终形成雪花状结构龙骨，叠加钢化玻璃的形式。将顶部中心向内凹，形成雨水回收的低点，利用桥墩柱向下排水，保证廊架下方足够的风雨遮蔽空间。用网状龙骨拉紧廊架，边缘处做到最小的420mm梁高，并直接用结构外露的形式，保证最小高度，再由幕墙专业于主龙骨中部区域进行外饰面衔接，以优美曲线衔接至完成面。

Given the bridge’s location within the river channel, multiple factors—seismic resistance, wind loads, and structural load capacity—posed significant challenges to the structural testing of the large-span cantilevered colonnades. The largest, Colonnade No. 1, features a cantilever width of 16 meters. To achieve an ultra-thin and sleek edge profile, numerous structural iterations were explored. Ultimately, a snowflake-shaped structural keel combined with tempered glass was adopted. The roof center was carefully designed with a concave profile, forming a low point for rainwater collection. Rainwater is drained through the bridge pier columns, ensuring ample shelter underneath the colonnade from wind and rain. The colonnade is tensioned using a net-like structural keel, with the edge beam height minimized to 420 mm. The structure remains exposed, maintaining its minimal height. Curtain wall specialists seamlessly integrated the external finish in the central area of the main keel, achieving an elegant curved transition to the final surface.

三处廊架分别被赋予桥面清吧、交子书吧、交子广场的使用功能，为将来运营提供可能性，最大化提升市民休闲体验感，也使得场景活化，加强与人的交互联系，提供更多有功能性的景观场景空间。

The three colonnades were designed to accommodate diverse uses, including a bridge deck bar, a Jiaozi-themed book bar, and a Jiaozi Plaza, providing opportunities for future operations. These multifunctional spaces enhance the public’s leisure experience, activate the area, and strengthen interaction between people and the landscape. The resulting design offers more functional and engaging landscape spaces.

桥面互动的实现：水幕SHOW场、彩虹草坪及幻彩水秀

Interactive Bridge Features: Water Screen SHOW, Rainbow Lawn, and Illumination Water Display

水幕SHOW场

Water Screen SHOW

人行桥面公园的位置也是规划的未来锦江夜游的一个重要点位，所以于桥面正中空开处，利用桥与水面的高差，布置了一处可多角度观看的互动雾幕。利用加压的水柱向水面形成雾柱，再结合声光的配合，于环的下方利用底部吊顶轮廓，通过隐藏设置六台投影设备，利用极小的投射夹角，于雾幕背面形成画面。

The bridge deck park is a key landmark for future Jinjiang River night tours. To enhance this experience, an interactive mist screen was installed in the open central area of the bridge deck. Utilizing the elevation difference between the bridge and the water surface, pressurized water jets create vertical mist columns. Integrated light and sound effects, combined with six hidden projection devices set beneath the circular ceiling structure, project visuals onto the mist screen at precise angles.

▲夜幕下，两岸围观雾幕的人们

同时，需要精细考虑检修方案，电动升降、河面行船检修等都被放弃后，只能依靠桥的结构空腔内找通道，于内部布置环状马道，实现检修的可达。

Maintenance was a critical consideration. After evaluating and rejecting solutions like electric lifts or boat-based repairs, an internal circular maintenance catwalk was incorporated into the bridge’s structural cavity, enabling safe and efficient access for maintenance.

通过这一节点内容的设置，实现夜游时桥面桥下皆能感受到节点内容的魅力，实现多维度景观共赏的目的，并且联通锦江及两岸可游可观的游览目的。给夜间出行的市民一处共赏、打卡的目的地。

This design ensures that both the bridge deck and the space below can captivate visitors during night tours, offering a multi-dimensional scenic experience. The project connects Jinjiang River and its banks, providing a shared landmark and a vibrant nighttime destination for visitors.

在布置好夜间的景观点位的同时，白天也呼应主题，设置一处人造彩虹。根据太阳高度角的位置，在桥面合拢后实时进行现场检测，调整规划了最适合桥面成型的角度方位和观看时间，同样利用加压水柱（但控制喷射出口控制，对人体无危害）向上形成喷射柱，形成水雾墙后，在20米左右范围形成最佳观赏点。

While the nighttime experience is captivating, the daytime design also complements the theme with a manmade rainbow feature. The system uses pressurized water jets (with controlled, harmless outlets) to form upward mist columns. Through real-time testing of the sun’s elevation angle after bridge construction, the optimal position, angle, and viewing times were identified to create a 20-meter radius optimal observation point.

The water feature consultant, Susui Design, conducted on-site angle and data measurement and collection on the bridge deck according to the original planned location of the rainbow. After analysis, it recommended a more suitable location for the rainbow. We carried out the implementation design based on the new location to ensure a balance between technical feasibility and amusement.

▲彩虹下，玩耍的孩童们  

Children play joyfully under the rainbow

水柱虽然加压，但受风的影响较大，且单位立方的水量需要回收再利用。在这基础上，是否利用大量的水柱落下后，形成可戏水的场所，成为小朋友大朋友都能互动的空间。于是我们利用环形水域的形态，将加压喷头安全隐藏起来， 利用无棱角的造型处理，在水池中形成游戏水道，配合夜间星星灯及投射灯的光影，形成白天夜间都能玩乐的游乐场。

Although the pressurized water jets achieve the desired effect, they are highly susceptible to wind and require water recycling for sustainability. To address this, the design evolved to create a playable water space for both children and adults. Utilizing a circular water zone, the pressurized nozzles are safely hidden, and rounded-edge forms ensure safety. The water area doubles as a playful waterway during the day and transforms into a magical nighttime playground with starry lights and projection lighting effects.This design ensures an engaging, interactive experience for visitors of all ages, seamlessly transitioning between day and night.

幻彩水秀

Illumination Water Show

在引桥一侧，有一处嬉水乐园，取荷叶上五色露珠的概念，需要还原幻彩互动水景的效果。在旱喷开启与不开启时皆有景可观，同时考虑到夏季夜间散步玩乐的市民数量巨大，考虑夜间光彩与旱喷水景结合，增加该区域的互动可玩性。

On one side of the approach bridge, a playful water park was designed, inspired by the concept of colorful dewdrops on lotus leaves, aiming to recreate an iridescent interactive water feature. The design ensures visual appeal whether the dry fountain is active or inactive. Considering the high number of visitors during summer evenings for strolls and recreation, the integration of lighting effects with the water fountain enhances the interactivity and playability of the space.

我们从材料上着手寻找，在漫水的反光材质上达到炫彩效果且保证戏水的安全性、保证一定的防滑度。经过多次寻找和实验，最后选定用支撑器+炫彩防滑玻璃的做法来实现。采用19mm防滑处理超白钢化玻璃+2.28SGP+10mm炫彩片+2.28SGP+19mm超白钢化玻璃+2.28SGP+19mm超白钢化玻璃，在阳光下呈现不同的炫彩光晕。再利用支撑器放置调平，保证上人面的平整度及稳定性。保证所有面层不留余水，及时实现回水利用的目的。

We focused on material selection to achieve the iridescent effect on water surfaces while ensuring safety, slip resistance, and usability. After extensive trials and experiments, the final solution employs supporting devices with iridescent anti-slip glass. The materials include:19mm anti-slip ultra-clear tempered glass + 2.28mm SGP + 10mm iridescent film + 2.28mm SGP + 19mm ultra-clear tempered glass + 2.28mm SGP + 19mm ultra-clear tempered glass.This combination creates colorful halos under sunlight while maintaining structural integrity. Supporting devices allow precise leveling, ensuring a stable and even surface. Additionally, the system ensures effective water drainage with no water accumulation, enabling efficient water recycling.

Through detailed design and careful integration of multiple disciplines, the key nodes achieve a vibrant, interactive, and functional bridge park that provides distinct day and night experiences with intelligent control systems. This creates a versatile leisure destination, offering a variety of engaging and interactive experiences for the public.

实现桥面公园的必要环节 植物篇章

Essential Components of the Bridge Park: Planting Chapter

因该河段有通行功能，需要尽量高和宽的桥下空间来保证航道及行洪，因此通体采用四根直径两米多的桥墩柱支撑整个桥面。同时因为这样布置的桥墩柱形式，对整个桥面的荷载总量也提出更高要求。人行桥为全钢体桥结构，除开桥体自身重量之外，桥面的公园系统，包括种植土、植物、小品、桥面铺装、水电管网等，都需要精细化设计及控制，以满足这一前提条件。

Due to the river’s navigational requirements, the bridge design prioritizes ample clearance and width below to ensure the waterway's flow capacity and vessel passage. The bridge deck is supported by four columns, each with a diameter of over 2 meters. This configuration imposes stricter limitations on the bridge’s overall load capacity. The pedestrian bridge, constructed entirely of steel, requires careful design and control of all deck systems, including planting soil, vegetation, amenities, paving, and utility networks, to meet these structural constraints.

▲空中俯瞰环雾草坪

通体钢桥的形式对于在其上层种植植物本身有一定影响，其传热导热性能在夏季高温时会使得种植基层温度聚集升高，影响植物根系生长。我们在钢桥面布置防水耐穿刺的保护层，再设置排水板以达到隔离、排水的作用。另在重点乔木根系处布置土壤传感器，实时监控乔木土壤湿度，根据实时数据采取对应养护措施。

The all-steel bridge structure poses challenges for plant growth due to its thermal conductivity. In high summer temperatures, heat transfer can elevate the planting substrate temperature, negatively impacting tree root systems. To address this, a waterproof, puncture-resistant protective layer was installed on the steel bridge deck, followed by drainage boards to provide insulation and drainage. Additionally, soil moisture sensors were placed near key tree roots to monitor real-time soil humidity and inform targeted maintenance efforts.

▲桥面乔木种植示意图  

Diagram Illustrating Tree Planting on the Bridge Deck.

▲彩虹草坪上种植的巨大体量的大乔

Large-scale trees planted on the Rainbow Lawn create a commanding visual presence.

在桥面上的乔木存在阵列和点植两种形式。点植在草坪上的大乔除了对土壤、根系定点检测以外，还需要设置固化的隐藏种植池来固定根部且表面形态自然融合。阵列的乔木使用独立种植池来完成桥面种植，在定制的不锈钢种植器内部同样布置防水涂层并固定于钢桥面，以轻质透水材料置于底部，且布置导水管解决浇灌及雨水渗透，形成单独种植池以布置二乔。

Two planting methods were implemented for trees on the bridge deck.Spot Planting: For individual large trees on lawns, concealed planting pits were created to anchor roots securely while seamlessly blending with the natural landscape. Real-time soil and root condition monitoring ensures health and stability.Array Planting: Independent planting pits were used for rows of trees. Custom stainless-steel planters were lined with waterproof coatings, fixed onto the steel bridge surface, and filled with lightweight permeable materials. Integrated drainage pipes manage irrigation and rainwater seepage, ensuring optimal conditions for growth.

▲桥上的树与滨河的树形成空间对望

Trees on the bridge align with those along the riverbank, forming a visual connection between spaces.

通过这些操作处理，最大限度保证桥面乔木存活及良好长势。在经历过项目开放的夏季后，这一系列保证措施得以证实其对乔木生长的有力保证。

These measures ensure maximum tree survival and healthy growth. Following the project’s first summer season after completion, these strategies have proven effective in supporting tree vitality.

同时，我们在深化过程中，尽量控制桥面及桥下乔木品种的风貌及系统。在桥面尽量以干练有表现力的、适应性较高的单一品种承接桥面公园整体性；而桥下则是自然系统，与滨河绿地柔性衔接。

At the same time, during the design development process, we have worked to control the aesthetic and systemic characteristics of the tree species both on and beneath the bridge. On the bridge deck, we prioritized a single, expressive tree species with high adaptability to maintain the overall integrity of the bridge park. Beneath the bridge, we focused on creating a natural system that integrates smoothly with the riverside green space, fostering a flexible connection with the landscape.

桥下灰空间的利用

Utilization of the Under-Bridge Grey Space

公园西侧滨河步道平均宽度较窄，在交子桥下方区域更显郁闭，我们考虑到此处本身为一处停留休憩的节点空间，是否可以将桥上下空间联通，做更多功能性布置呢？因此利用两侧延续的退台挡墙进行连接，形成一处内凹挡墙，将滨水步道空间内退扩大，并结合幻彩水秀的节点打造，将出挑区域形成透明互通的空间，上下视线联动。再结合内退空间形成少量台阶，布置水电，即为将来运营点位提供可能性，也解决桥下观众观看水幕SHOW场的看台功能。

The riverside walkway on the west side of the park is relatively narrow, and the area beneath the Jiaozi Bridge feels particularly enclosed. Recognizing this space as a potential rest and gathering point, we explored opportunities to connect the space above and below the bridge and incorporate more functional elements. Therefore, we utilized the stepped retaining walls on both sides to create a recessed retaining wall, which expands the riverside walkway space. By integrating this with the location of the colorful water show, we formed a transparent, interactive space in the protruding area, allowing for visual connection between the upper and lower levels. Additionally, a small set of steps was added to the recessed space, along with the installation of water and electricity utilities. This design not only provides potential for future operational use but also resolves the issue of creating a viewing platform for the audience to watch the water curtain show beneath the bridge.

交子人行桥面公园区域，是在金融城片区一处重要城市绿地链接节点，是未来周边市民生活休闲的一处重要绿色纽带。现阶段金融城东区正处于建设期，待各地块产业落位呈现时，交子绿轴公园、滨江绿道区域会吸引更多市民的参与及使用。沿江两岸布局了根据产业内容延展出来的各种商业服务业态，也会一并链接因人的聚集而产生的新消费业态，在设计前期，将这一因素考虑进去，在空间形态及功能配合上去做更多预留，以备未来时需。

The Jiaozi Pedestrian Bridge Park is a key urban green link within the Financial City district and serves as an essential green corridor for nearby residents. As the Financial City East District continues its construction phase, this green connection will play a pivotal role in attracting citizens to the Jiaozi Green Axis Park and the riverside greenway. With the planned development of surrounding industries and the introduction of various commercial and service-oriented functions, new consumption patterns driven by human activity and gatherings will emerge.During the early stages of planning and design, this factor was anticipated, and provisions were made in the spatial layout and functional design to accommodate future demands.

Its extensibility and tensile (deformation) strength meet the requirements for steel bridge deck paving conditions）

交子人行桥面公园开放后，链接了交子绿轴公园、滨江绿道的游逛体系，吸引了大量市民前去休闲游逛。无论是晨起暮色时分的跑步、骑行人群，下班后附近散步的居民，夏日傍晚在桥上与水嬉戏的孩童，还是将来夜游开通后参观的游客，都将从各个角度全方位的感受到这座“绿桥”的魅力。随着时间的脚步，四季的更迭带来更多场景的变化和感受，静静的伴随这座城市的发展，作为片区发展的见证者。

Following the opening of the Jiaozi Pedestrian Bridge Park, it has successfully linked the Jiaozi Green Axis Park and the riverside greenway, attracting a large number of visitors for leisure activities. Whether it is runners and cyclists in the early morning or evening, residents enjoying a post-work stroll, children playing in the water on summer evenings, or tourists admiring the night tours, the bridge offers a unique multi-dimensional experience.Over time, the park will reflect the changing seasons, offering a variety of evolving scenes and sensory experiences. Quietly accompanying the city's growth, the bridge stands as both a functional landmark and a witness to the area's development, fostering connections between the environment, the community, and the future of urban life.
