Phyllis Tilley Memorial Bridge

The Phyllis Tilley Memorial Pedestrian Bridge crosses over the Trinity River connecting Trinity Park to a new trail leading to downtown Fort Worth. The bridge's graceful profile enhances the serene landscape. A steel arch supports the steel stress ribbon and precast concrete planks over the river, complementing the adjacent historic Lancaster vehicular bridge. At night, the bridge is illuminated by a combination of white and blue LED lighting for increased safety and aesthetic appeal. This elegant and cost effective bridge will become a visual asset along the Trinity River and a new symbol of the City of Fort Worth. This steel stressed ribbon / arch combination bridge is the first of its kind in North America.
