WALLINGFORD — The state’s transportation agency recently added a fourth bridge to the list of structures to be replaced on Interstate 91 in Wallingford. The scope of the project, administered by the Connecticut Department of Transportation, encompasses bridges that carry the highway over East Center Street, Durham Road and New Rock Hill road, and now, Carpenter Lane. Construction is projected to start in spring 2028 and be completed by the end of 2030, according to the DOT. The estimated cost is between $60 million and $90 million. It is expected to receive 80% of that cost in federal funds and 20% in state funds. The DOT held an informational meeting in September 2025 to discuss the first three bridges, and another in late June for the fourth one. Beth LaPlante, the task lead and senior project engineer at the HNTB design consultant firm, said during the June 24 session at Town Hall that the Carpenter Lane bridge is at the northern limits of the project area. The work will address “structural deficiencies” to achieve a design life of at least 75 years, she continued.
