SOUTHINGTON — The town is finalizing plans to replace bridges on Spring Street and Marion Avenue next year.
The work, slated to begin in spring, will slow travel on both roads.
Public Works Director Keith Hayden said portions of both bridges were rated as in poor condition by the state Department of Transportation.
On Spring Street, traffic will be alternating one way during construction. The traffic flow for the Marion Avenue bridge over Humiston Brook has not been decided.
Town councilor John Barry, who chairs the public works committee, said the panel has debated the merits of closing the bridge and allow alternating traffic.
Alternating traffic lessens disruption to drivers but lengthens the construction time.
“There is some cost savings in terms of closing,” Barry said. “Both projects are big projects and will require some patience with residents. There will be some changes in the traffic flow...”
The Spring Street bridge was built without a waterproof membrane protecting the deck, leading to deterioration. Water damage has caused concrete on the Marion Avenue bridge to break off and in some cases expose the steel rebar.
“It’s safe for traffic, but it needs to be replaced,” Hayden said.
When planning work near Humiston Brook, Barry said the public works committee wanted to make sure no environmental damage was done.
“Humiston Brook is extremely clear, clean water,” he said. “It’s important that there’s a lot of sensitivity in terms of the environment.”
Both projects are funded mostly with state and federal grants. Southington is paying about $440,000 of the total $2.2 million for the Spring Street bridge work, with a federal grant funding the difference.
Hayden said the state was paying the approximately $1 million for the Marion Avenue bridge replacement work. The town paid for engineering work, which will total about $200,000.
Barry was glad that the Public Works Department was able to secure the grants.
“It absolutely helps the impact to people’s local property taxes,” he said.
