The highway will close in both directions to all traffic at Exit 30 for Marion Avenue in Southington for the weekend of June 27 to 29 for bridge replacement work, the Connecticut Department of Transportation said.
It is scheduled to reopen Monday morning, June 30.
Major traffic delays are expected, and motorists are urged to plan ahead, avoid the area and seek alternative routes, DOT said.
Suggested alternate routes for drivers include I-91, I-691, Route 9 and Route 72. Local detours are established for residents and businesses in the area surrounding the construction site and signs will be posted.
Drivers seeking alternate routes could add to the traffic on I-95, I-91 and the Merritt Parkway, as well as other roads, DOT said.
While the highway is closed, two bridges that carry I-84 over Marion Avenue, one eastbound and one westbound, will be replaced with new structures that have been built alongside the existing bridges.
The replacement will require the complete closure of I-84 in both directions over Marion Avenue and will be completed in one weekend.
Beginning at 5 p.m. Friday, June 27, Marion Avenue will be closed for the duration of the work. The Exit 30 on and off ramps will also be closed for three hours to set up traffic control and staging for the full closure of I-84.
At 9 p.m. Friday, I-84 will be closed to all traffic and the on and off ramps at Exit 30 will be reopened to channel a single lane of I-84 traffic around the closed section of highway.
All roads are scheduled to reopen by 5 a.m. Monday, June 30.
