7th Street Salt River Bridge Reconstruction

Located in the heart of metropolitan Phoenix, the 7th Street Bridge is one of only six bridges to cross the Salt River in this area. Unexpectedly, one of the bridge's gas lines lit on fire, making it unsafe to use. The damaged area of the bridge required removing and replacing two of the five spans, one pier and the abutment, the roadway, and 100 feet of road that transitioned into the bridge. In addition, to aid utility companies needing to get utility lines back into the bridge, we had to tear off and replace the south side of the approach. Replacing the roadway meant replacing five lanes—two lanes in each direction with a center turn lane and a sidewalk on both sides separated by a barrier. Work included demolition, girders, substructure, superstructure, civil improvements, wet and dry utilities, and coordination with multiple utility providers.
