West 7th Street Bridge
- Oct 11, 2013
The new West 7th Street Bridge was opened in October 2013 consisting of 12 precast concrete network arches, each measuring 24 high with spans of 163 ft. The arches are more than aesthetic, separating the roadway from the two 10 ft wide sidewalks, enhancing pedestrian safety. The project resulted from collaboration between the City of Fort Worth, TxDOT and Sundt Construction resulting in an east‐west thoroughfare connecting downtown to growing mixed‐used developments and the Cultural District.
Building Information Modeling, or BIM, was extensively used to assist with the complexity of the project, particularly the construction of the arches as they contain many structural and lighting elements that have the potential to clash with one another if not planned precisely.
The use of precast construction resulted in less traffic delays and minimized on-site construction. Epoxy-coated reinforcing steel was used in many of the elements, including the deck to enhance long-term durability.
