New Gloucester Toll Diversion Study

The purpose of this study is to understand the levels of traffic that likely divert around the New Gloucester Toll Plaza on the Maine Turnpike (I-95) between Exits 63 and 75.

GPCOG staff used traffic analysis zones from the regional travel demand model to identify which geographic areas would have a travel time savings when taking the Maine Turnpike (I-95) through Gray and New Gloucester compared to other routes. Staff then analyzed cell phone data (using data from StreetLight, a third-party data vendor) to identify the magnitude of trips originating or ending in the zones that divert around the tolls in New Gloucester.

The findings from this study, which are based on best-available data, approximate the levels of diversion around the New Gloucester Tolls. The results can inform subsequent discussions of potential policy and planning responses to toll diversion and other traffic issues in Gray and surrounding communities.
