公园联合桥

项目为科罗拉多斯普林斯提供了一条重要的城市纽带，它跨越了以前作为障碍物的活跃的铁路货场。通过将Vermijo大道的东西轴线延伸到美丽美国公园，新的人行桥重新连接了科罗拉多泉市中心的城市结构。该桥还将一个不断增长的步行自行车道网络连接起来，包括派克峰绿道和纪念碑溪边的米德兰小道。

Park Union Bridge provides a vital urban link for Colorado Springs, spanning over an active railyard that previously acted as a barrier. By extending the east-west axis of Vermijo Avenue to the America the Beautiful Park, the new pedestrian bridge reconnects the urban fabric of downtown Colorado Springs. The bridge also stitches together a growing network of pedestrian bicycle paths including the Pikes Peak Greenway and Midland Trail running alongside Monument Creek.

新的人行桥由邻近的美国奥运会和残奥会博物馆的同一个团队设计，它从运动员的重力挑战运动中获得灵感，有一个250英尺的弧形钢结构，漂浮在堆场之上。两个互锁的环形结构，从铁路场的两侧延伸，连接博物馆和公园。DS+R主管合伙人兼首席设计师Benjamin Gilmartin指出："这座桥是一项健身运动--在材料和几何方面都是如此。混合钢结构系统具有拱形和桁架的功能，优雅地保留了从市中心到派克峰雄伟山脉的景观"。

Designed by the same team as the adjacent U.S. Olympic & Paralympic Museum complex, the new pedestrian bridge takes its inspiration from the gravity-defying motion of athletes, with a 250-foot curved steel structure that floats above the railyard. Two interlocked loops, stretching from either side of the railyard, connect the museum and the park. DS+R Partner-in-Charge and Lead Designer Benjamin Gilmartin noted, “The bridge is an exercise in fitness - both in terms of material and geometry. The hybrid steel structure system functions as an arch and a truss, elegantly preserving views from Downtown to the majestic mountain ranges of Pikes Peak.”

这座桥很宽，可以安全地容纳行人和骑自行车的人。在它的最宽处，桥的两边有一个椭圆，东边是博物馆和市中心，下面是火车观光的平台，西边是明显的落基山脉的视野。在晚上，沿桥的照明从铁轨的一侧追溯到另一侧，给人以速度和运动的感觉，同时为行人和骑车人提供照明。

The bridge’s generous width safely accommodates pedestrians and cyclists alike. At it’s widest point, an oculus at either side of the bridge frames the museum and downtown to the east, a platform for trainspotting below, and a distinct look out to the Rocky Mountain to the west. In the evenings, lighting along the bridge traces a single vector from one side of the tracks to the other, giving a sense of speed and motion while providing illumination for pedestrians and cyclists.

项目在德克萨斯州休斯顿的一个中转区组装，并于2020年5月进行了全面安装。在一个周末的时间里，使用自走式模块运输车将这些部件推进到位，最大限度地减少了铁路线和货场的停工。随着桥梁部分的交付，桥梁在地面上被组装起来，将每个部分焊接在一起。桥梁部分的组装在2020年6月底完成。2020年10月，在一个精心策划的过程中，桥梁被整体吊起并放置在桥墩上，在8小时内完成。

The prefabricated bridge was assembled in a staging area in Houston, Texas and a full fit-up was conducted in May 2020. The pieces were driven into place using self-propelled modular transporters over the course of a single weekend, minimizing outage for the rail lines and yard. As bridge sections were delivered, the bridge was assembled on the ground to weld each section together. Assembly of the bridge sections was completed at the end of June 2020. In October 2020, the bridge was hoisted and placed onto its abutments in its entirety in a carefully orchestrated process completed within an eight-hour window.
