Maine State Route 175

State Route 175 (SR 175) is a state highway entirely in Hancock County, Maine that travels for 37.8 miles (60.8 km). The shape of the route is an unusual U-shape and travels along the peninsula surrounded by Blue Hill Bay, Eggemoggin Reach, and Bagaduce River. The route is signed as north-south but has two northern termini: at State Routes 15, 172, and 176 in Blue Hill, and at SR 166 in Penobscot. The transition point of the directional signage occurs about 2+1⁄2 miles (4.0 km) from the Blue Hill terminus.
