Adams' Quality Street Bridge to Be Replaced
The state Department of Transportation is anticipating construction to begin in fall 2025 and to take from one to two years. Residents on the dead-end South Willow Street will employ an easement to Grove Street first used when the bridge was constructed back in 1950.
"It's a rather large bridge and the demolition is going to take a while," said structural engineer Micah Morrison at Thursday's public hearing. "There's a whole process that's involved, but it does take a while."
The bridge was rated as poor when it was inspected in September.
"The outside girders, which are the main load carrying members are heavily rusted," said Morrison. "The bottom photo shows a hole in the stringer that supports the bridge deck. Due to this deterioration, the bridge was analyzed and vehicular weight restrictions were imposed."
The 82-foot steel bridge will be replaced by a 96-foot prestressed concrete span and the overhead wires will be relocated to the north of the bridge. A temporary utility bridge will be installed to carry a 20-inch water main and 2-inch gas main.
The substandard guardrail will be updated, he said, and the roadway repaved "with a robust asphalt providing a stable base layer to provide a safe, modern, low-maintenance bridge with a minimum service like 75 years."
The bridge is at least 75 years old — the girders were used in Pittsfield to carry Pomeroy Avenue over the Housatonic River until a new bridge was installed there in 1950. It was part of the Maple Grove project that straightened out and widened Grove Street over the Hoosic River and rail line, and cost an estimated $500,000 total the time. The small wooden bridge to South Willow Street was removed (along with some homes) and Quality Street extended to connect the landlocked road.
MassDOT says the bridge carries about 129 vehicles a day. The bridge replacement was approved in 2020 and it is currently at 25 percent design with permitting and 75 percent design to be reached this year. Bidding is anticipated for summer of 2025 with construction beginning that fall.
It has an estimated cost of $4.1 million and is planned to be funded through the 2025 Transportation Improvement Program for the Berkshire Metropolitan Planning Organization. Federal highway funding will account for 80 percent of the cost.
The town is responsible for acquiring the five permanent and nine temporary easements for the project.
"Environmental permitting was minimized by lengthening the bridge and building the proposed substructure behind the existing substructure project," said Morrison. "It will acquire the appropriate federal and state environmental permits prior to advertising the project."
With the bridge connecting South Willow to Quality Street inaccessible, the residents of South Willow will be directed east over the Ashuwillticook Rail Trail to access Grove Street. Temporary traffic controls will be installed on the rail trail.
Morrison did not anticipate any problems with traffic rolling over the pedestrian and bike trail.
"We understand that's a concern but when we've looked at other crossings of the rail trail there are multiple other crossings, at grade crossings, along the rail trail," he said. "There will be minimal vehicles that will be using this but we will be looking into it further as the project moves forward."
No residents asked questions during the virtual hearing but John C. Barrett, superintendent for the Adams Water Department, said he had not been informed about the plans and asked that the district be included on any communications.
