Even before construction of the 4-lane highway, this crossing was the primary route between Montreal and Boston, because it was where US Route 7 crossed into Canada. Route 7 now merges with I-89 prior to crossing the border. When Autoroute 35 is extended to the Canadian side of the border in 2023,[2] there will be a nonstop limited access highway from the second largest city in Canada to Greater Boston.
Through the Infrastructure Investment and Jobs Act of 2021, the United States designated $170 million to modernize the border crossing facilities, with $85 million in federal funds coming from the 2022 Consolidated Appropriations Act. Improvements on the facilities are intended to support the expected increase in traffic from the completion of Autoroute 35, with additional lanes for passenger vehicles, as well as for trucks and commercial traffic.
