Maplewood Avenue Bridge

Maplewood Avenue Bridge Project

 

Maplewood Avenue Bridge IS CLOSED TO VEHICLES to finish utility upgrades and to replace the roadbed and north-side sidewalks and railings, continuing through mid-June.

Work will be taking place on Saturday, June 7, 2025. The bridge remains closed with detours in place. For details see route maps below.

Once the north side of the bridge is finished (by the end of June), the current plan is to open one lane of the bridge for traffic heading toward downtown for the balance of the bridge work as the contractor replaces the sidewalks and railings on the south side. Completion date for the entire bridge is anticipated to be in November 2025.

The current schedule shows the bridge work being complete in November.

Pedestrians and cyclists (walking their bikes) will have access across the bridge on whatever side is not currently under construction.

See detour options, below.

DETOUR ROUTES: 

The new traffic pattern detours vehicles around the bridge via the Route 1 Bypass, Market Street, Russell Street and Deer Street. Pedestrian access will be maintained via the southern sidewalk. This traffic pattern is anticipated to remain in place throughout the rest of the 2024 construction season.

Project Description:

This is a rehabilitation of the bridge using an adhered lining system on the arch and reconstruction of the walls as necessary.  This will allow the City to extend the lifespan of the bridge without the cost of an immediate full replacement. This rehabilitation work will also include reconstructing the sidewalks and replacing the bridge’s guard rails in the spring of 2025 and resurfacing of the roadway in the late summer of 2025.  This repair work is intended to rehabilitate the bridge and make it suitable for use for at least another ten years.  

Estimated Completion: June 2025 for substantial completion. Final by November.

Cost: $4,000,000.

Funding Source: Included in CIP FY24-29 with funding from bonds.

Designer/Contractor: HTA Engineering, Evroks Construction Co.
