Several bills have been introduced that reflect lawmakers’ concerns over a proposed east-west highway, a 230-mile route across Maine that would connect Canadian points. The highway would be operated privately and be maintained with tolls. The bills are being drafted, so all of their details are not known. But the titles show that one would take away the $300,000 state appropriation for a feasibility study on the project, and another would modify that appropriation. Other bills would restrict the use of eminent domain, to protect property owners along the proposed route, and one would create a special commission to oversee further study for an east-west highway.
