Maplewood Avenue Bridge

Maplewood Avenue Bridge WILL AGAIN BE CLOSED TO VEHICLES to finish utility upgrades and to replace the roadbed and north-side sidewalks and railings, starting Monday, April 7, 2025 and continuing through mid-June.
Once the north side of the bridge is finished, 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.
The current schedule shows the bridge work being complete in early 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.

Answers to Frequently Asked Questions
- What are the construction hours?
- Monday-Friday, 7 am to 6 pm, although some work will need to be done at low tide, which will affect the project when work is being done on the culvert under the bridge.
- Will there be construction work on weekends?
- No weekend work is anticipated unless there are delays.
- Will vehicular traffic be able to use the bridge on weekends if construction is not taking place?
- No, the bridge will not allow vehicular traffic during the closure. Once the bridge begins to take form again in the fall, it will reopen partially and flaggers will be used to one lane of alternating traffic while the work crew is finishing the sidewalks and railings.
- Is there a preferred detour that will allow people to get into town?
- Maplewood Avenue traffic will be detoured to the Route 1 Bypass and Market Street. The Bartlett Street Project is also proceeding and more access there will be available soon.
- Will the tide continue to flow in and out of North Mill Pond?
- The diversion pipe has been functioning since its installation the week of October 14 to allow the tide to flow back and forth, but on a limited basis. Since the pipe is only 60" in diameter, much less water than normal can enter and exit the pond for now. The system is being actively managed regarding flow to prevent the cofferdam system on the pond side from being overwhelmed.

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: At this time, it is anticipated that the bridge will reopen for the winter season and that the contractor will return in the spring of 2025 to replace the sidewalks. Final paving will be completed in the summer/fall of 2025. June 2025 for substantial completion.
Cost: $4,000,000.
Funding Source: Included in CIP FY24-29 with funding from bonds.
Designer/Contractor: HTA Engineering, Evroks Construction Co.
