Portland Area Widening & Safety Improvements Overview


The Maine Turnpike’s Portland-Augusta section opened in 1955. After more than six decades and a 1700% increase in traffic, it’s time to repair, improve, and widen this busy stretch through the Portland area.

When completed, drivers will enjoy a safer highway, less traffic congestion, and a smoother, more efficient shortcut around Portland—paid for 100% by Turnpike tolls. During this multi-year construction phase, please drive carefully, obey reduced speed limits in work zones, and imagine traveling a better Turnpike going forward.
