Forest Avenue Weekend Closure Between Marginal Way & 295 from November 10 - 13

traffic alert

Starting at 10:00 pm on Friday, November 10th, the City of Portland will shut down Forest Avenue between Marginal Way and Interstate-295 for the weekend as part of the State Street Infrastructure Improvements project. The city’s contractor will cross Forest Avenue with new storm drain infrastructure that will link the State Street storm drain to the new storm drain outfall recently installed at back cove.  This work is part of the City’s on-going effort to reduce Combined Sewer Overflows into Back Cove. The City has chosen to have its contractor perform this work over the course of one weekend with a full shut down as opposed to a partial shut down over the course of one month in order to lessen disruptions. 


IMPORTANT INFO FOR MOTORISTS:  Forest Avenue will be shut down between Marginal Way and Interstate 295 starting at 10:00 pm on Friday, November 10th and reopen to traffic on Monday, November 13th at 7:00 am.
