Salem — Preparations for a Connecticut Department of Transportation project to widen part of Route 85 in Salem will begin this week and run into the summer.

Traffic delays are expected between Skyline Drive and the Shady Brook picnic area from 7:30 a.m. to 2 p.m. Monday through Friday until Sunday, July 2.

The project, which will widen the road and provide additional drainage to improve safety and operation, will start in September and run through November. Construction in the fall will take place from 6 p.m. to 8 a.m., and alternate routes will be advised.
