Interstate 84 will be closed in both directions for 56 hours this weekend, and the Connecticut Department of Transportation is warning motorists that major traffic delays are anticipated. The road will be closed at Exit 30, Marion Avenue in Southington Friday, June 27, and is scheduled to reopen Monday morning, June 30. Suggested alternate routes 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. Two bridges that carry I-84 over Marion Avenue, one eastbound and one westbound, are being replaced with new structures that have been built alongside the existing bridges.\u00a0 The replacement will require the complete closure of I-84 in both directions over Marion Avenue and will be completed in one weekend. The Southington Rest Area, located west of Exit 30 on I-84 East, will close at 9 a.m. Friday, June 27, and re-open at 5 a.m. on Monday, June 30. No parking along I-84 or entrance areas of the rest area will be allowed. Beginning at 5 p.m. Friday, June 27, Marion Avenue will be closed to through traffic for the duration of the work. The Exit 30 on and off ramps will also be closed for approximately three hours to set up traffic control and staging for the full closure of I-84. At 9 p.m. 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.\u00a0 Marion Avenue will remain closed to through traffic and there will be no access to the interchange area.\u00a0 All roads are scheduled to be re-opened by 5 a.m. on Monday, June 30. A full outline of the closures can be found on the DOT website. The public will not have access to the project area during the weekend closure. The DOT has installed web cameras at the site so the public can access live video and HD time-lapse video during the closure period.
