PORTLAND — A city committee looking at ways to upgrade Forest Avenue will walk a section of the artery this afternoon and then hold a meeting to discuss the issues and challenges that can be found along the street.

The walk by the Transforming Forest Avenue Public Advisory Committee will start at 4:30 p.m. in front of the Glickman Library at the University of Southern Maine. At 6 p.m., the public meeting to talk about the stretch of the avenue between Park Avenue and Woodfords Corner will begin in room 109-110 of the Abromson Center on Bedford Street at USM.

The committee is working with a $100,000 Federal Highway Administration grant to help with creating the framework for design policies that allow pedestrians, bicyclists, buses and cars to move easily and safely along the artery while also promoting business and residential activity.
