[ARCHIVED] DPW Bridge Project - Court Street

The Court Street Bridge project will involve roadway and sidewalk reconstruction from Matthews Court to Addison Street and accelerated bridge construction (ABC). The ABC will involve a one month closure (April 2021) of Court Street to accommodate the installation of prefabricated bridge components. The detour will utilize the Route 3 bypass. The project includes an Ultra High Performance Concrete deck surface, which will be a first in New Hampshire. The UHPC aids in the accelerated construction and is effectively water-proof, aimed to mitigate future deck repairs within this busy corridor. Petroleum contaminated soils and groundwater will be removed from the site through participation with the NHDES Petroleum reimbursement fund. Existing water and sewer utilities will be reconstructed in the direct vicinity of the bridge utilizing trenchless technologies to speed construction, minimize disturbance of the channel, and further reduce contaminated soil handling. Drainage improvements from the previous Court Street projects will be continued through this project. The project is primarily funded by the NHDOT State Bridge Aid Program, with a 20% cost share for the City. In late August, three bids were received for the construction, with the lowest bid from Evroks Corporation of Northfield, NH. As of note, Evroks Corp. was the contractor for the recent, and successfully completed, Weirs bridge rehabilitation project which had a similar accelerated construction schedule.

The bridge closure is scheduled to occur in April 2021. Phased construction is expected to start this fall from October to mid-November. Evroks Corp. will remobilize to the site next spring starting in March. Following the bridge replacement in April, sidewalk and paving will be completed in May and June with final paving in July.
