Linden Street Over Exeter River Bridge Repair

As of 02/16/2024 all bids have been rejected. 1. General Project Description Rehabilitation of the Linden Street Bridge over Exeter River (Br. No. 081/046). Rehabilitating the timber bridge abutments and wingwalls by encasing within a soil nail wall, approach pavement repairs, and replacement of substandard bridge rail. 2. Rationale The existing timber bridge was built in 1993; abutments and wingwalls are showing signs of settlement and bulging. Shear connectors between individual timber facing beams have failed leading to further settlement. A soil nail wall encasement will stabilize the system to prevent further settlement. In addition, the existing bridge rail is substandard and should be replaced with an AASHTO-MASH crash worthy bridge rail. 3. Operating Budget Impact The estimated rehabilitation cost (including design, permitting, rehab and inspection) of $560,000 is based on July 2022 dollars; annual inflation rate of 8% should be applied to mid-point of rehabilitation. In August 2022 NHDOT will provide the Town of Exeter with $310,000 for bridge work; the balance would need to be raised and appropriated
