Motorists may face traffic stops Sunday night on the Maine Turnpike near the new E-Z Pass highway speed lanes at the toll plaza at mile 67 in New Gloucester.

Traffic may be stopped for up to 15 minutes between 10 p.m. and 2 a.m. Monday to allow workers to adjust signs and remove lane closures on both north and southbound lanes approaching the toll plaza.

The new highway speed toll lanes will open at midnight.
