WESTPORT — The Exit 17 Interstate 95 northbound on-ramp will be closed Monday, Oct. 16, through Oct. 31 so work for a bridge replacement project can be done.

The state Department of Transportation will establish a detour, using Riverside Avenue, the Post Road and the Sherwood Island Connector to the Exit 18 on-ramp.

“The ramp closure is necessary for work to improve the safety of the ramp in conjunction with the bridge slide,” the DOT said on its I-95 Norwalk Westport Project webpage.

The northbound half of the I-95 bridge over Saugatuck Avenue will be demolished this weekend, from 8 p.m. Friday, Oct. 20, through 6 a.m. Monday, Oct. 23. I-95 will be squeezed down to two lanes in each direction, and Saugatuck Avenue will be closed.

The southbound half of the bridge will be replaced from 8 p.m. Friday, Nov. 3, through 6 a.m. Monday, Nov. 6.

The plan is, on the two weekends, to close a side of I-95, demo the old span, then “slide” the new one into place. Read the Westport Journal’s recent story about the plan here.

This “slide-in” method is a part of method known as Advanced Bridge Construction.

The local work is part of the DOT’s $104 million I-95 Norwalk Westport Project. The DOT is running the project. Yonkers Contracting Co. is doing the work. The Federal Highway Administration is funding 90 percent of it, the state 10 percent.

The project area extends from Norwalk to the Saugatuck River Bridge in Westport.
