PORTLAND — Starting July 15, the Maine Department of Transportation (MaineDOT) will begin work on Forest Avenue from the Allen Avenue intersection to the Riverside Street intersection in Portland for a highway preservation paving project.

The project work will include cold milling of the existing pavement surface, paving of an ultra-thin bonded wearing course, and pedestrian safety improvements.

During the project, there will be shoulder closures and lane shifts during the day with two-way traffic maintained. At night, there will be one-way alternating traffic controlled by flaggers.

Motorists should expect delays and use caution when traveling through the work zone, according to MaineDOT, in a news release.

Work is expected to be completed by the end of August.

The contractor for this project is Coastal Road Repair of Westbrook, Maine. The contract amount is $993,253.10
