BLUE HILL - The Maine Department of Transportation will be conducting geotechnical borings near the Falls Bridge in Blue Hill between Monday, May 18th and Friday, May 22nd. The Falls Bridge carries Route 175 (Falls Bridge Road). We will need to close the bridge to traffic in order to conduct the borings. Route 175 traffic will be detoured to Route 172. This detour will be in place between 7:30 a.m. and 4:30 p.m. This work is needed as part of the final design for the replacement of the Falls Bridge. The Department may have to conduct more geotechnical borings later this summer.
