Exit 45 (the Maine Mall Exit) in South Portland is being reconstructed as a Diamond Interchange to accommodate growing traffic numbers with two new ramp toll plazas and wider bridge.  The existing bridge over the turnpike has been hit on numerous occasions by over height vehicles and will be replaced and raised to provide a 16.5-foot clearance over the Maine Turnpike. The existing barrier toll booths will be removed and two new ramp toll plazas on either side of the turnpike mainline will be constructed. See the rendering below.

Work on the project is anticipated to last until 2023 with the new roadways and toll plazas being operable in late 2022.  During construction there will be coordination and work on items including: drainage, lighting, utility coordination and relocation, signage, highway design, traffic signal design, and structural and civil engineering of the toll plazas and toll administration building.

Prior to this construction project, the area was preloaded with material to facilitate settlement. This project started in late 2019 and cost approximately $14.8 million. More on this process can be found here.
