A project to replace the Post Street Bridge downtown will begin on Wednesday, June 17. The bridge, which currently only carries pedestrian and bicycle traffic, will be closed for the next two years. See the detour routes for pedestrians and bicyclists.

“The Post Street Bridge is an important connector for our community, serving as a multi-modal link next to Riverfront Park. The reconstructed bridge will help to complete the vision for a Great Gorge Loop Trail and be part of the Centennial Trail,” says Scott Simmons, the City’s Public Works Division Director.

With a construction contract of $18.5 million, the bridge replacement is the largest single project the City will launch this year and is part of about $70 million in construction planned for 2020. A water main will be replaced in Post Street as part of the work. Parking will be limited on Post Street, and the Riverfront Park parking lot on Post just south of the bridge will be closed, along with half of the parking lot at Lincoln & Summit Blvd. on the north side of the bridge.

The replacement project is designed to keep the bridge’s concrete arches and retain its historic look. When complete, the bridge will have one northbound lane for vehicle traffic as well as pedestrian and bicycle routes. It also carries a critical 54-inch wastewater interceptor.

The 333-foot-long Post Street Bridge was built in 1917 and widened in 1937.  It is a reinforced concrete open spandrel deck arch bridge.
