After three years of work, a $56.7 million project that improved a 5-mile stretch of the Merritt Parkway is coming to an end.

The state Department of Transportation has announced that the project “will move to a full final alignment progressing east to west (Fairfield to Westport) as median reconstruction work is completed and temporary barriers are removed.”

With that phase complete, preparations now move for final paving for the parkway in the construction zone.

A milling project, which prepares the road for paving, will require the evening closure of the Exit 42 on and off ramps this week in Westport.

The work is scheduled from 6 p.m. to 6 a.m. Monday, July 13 through Friday, June 17.

Message boards will be placed on the parkway and at ramps to inform motorists of the impending closure date and time.

During the ramp closure a signed detour will be in place for affected ramps. Motorist that normally use the on or off-ramps at Interchange 42 will be guided to use the following detours:

EXIT 42 southbound off-Ramp closure and access to Weston Road (Rte. 57): Detour will direct motorists to use EXIT 41 southbound off ramp to Wilton Road (Rte. 33) and return to EXIT 42 northbound off ramp via the Exit 41 northbound entrance ramp.

EXIT 42 northbound off-ramp closure and access to Weston Road (Rte. 57): Detour will direct motorists to use EXIT 44 northbound off ramp to Black Rock Turnpike (Rte. 58) and return to EXIT 42 southbound off ramp and Rte. 57 via the Exit 44 northbound entrance ramp.

EXIT 42 southbound on-ramp closure and access to Rte. 15 southbound: Detour will direct motorists to use EXIT 42 northbound on ramp to Rte. 15 north and use EXIT 44 to Black Rock Turnpike (Rte. 58) and return to Rte. 15 south via the Exit 44 southbound entrance ramp.

EXIT 42 northbound on-ramp closure and access to Rte. 15 northbound: Detour will direct motorists to use the EXIT 42 entrance ramp to Rte. 15 South via Weston Road (Rte. 57) and use EXIT 41 to Wilton Road (Rte. 33) and return to Rte. 15 North via Exit 41 northbound entrance ramp.

Already, most of the construction work from Congresss Street in Fairfeld to Westport has been completed.

The project included work on 11 bridges uniquely designed for the Merritt in the 1930s by architect George L. Dunkelberger. While most of the bridges required minor cosmetic enhancements — such as parapet work, graffiti removal, surface and crack repairs, and fencing — others, like the Saugatuck River Bridge needed more work.
