Detours have been set because of the closed bridge.

PITTSFIELD, Mass. — Rapid deterioration of the Peck's Road bridge has led to its closure until further notice and a hopefully expedited process to replace the entire structure.

The bridge was fully closed to traffic on Monday following an inspection from the Massachusetts Department of Transportation that found six areas of deterioration. Repair work is slated to begin in August by Rifenburg Contracting Corp. and the city says it continues to work closely with MassDOT on steps ahead.

Work will include demolition and reconstruction of the bridge over Onota Brook that has been reduced to one lane for five years. A detour has been routed from Peck's Road to Onota Street, Vin Herbert Boulevard, and Valentine Road.

"Today, upon a 6-month routine inspection, the state found signs of rapid deterioration and ordered the bridge to be closed," Commissioner of Public Services and Utilities Ricardo Morales wrote in an email.

"We are now moving towards having the bridge replaced in one go, as opposed to splitting the work in phases and maintaining traffic flow. This has some setbacks but overall the project should be completed faster."

The bid was awarded to the contracting company for $1,535,420 with a 10 percent construction administration budget and a 10 percent contingency budget, bringing the total estimated cost to $1,842,504.

Morales reported that the city has multiple authorizations for funding from previous years and a state Small Bridge grant that will cover all of the costs. He said a schedule will be shared once the contractor finishes changing the construction approach.

Pedestrian access is still available until construction begins.
