Route description
SR 139 begins at an intersection with U.S. Route 201A, U.S. Route 2, and SR 8 in Norridgewock. The intersection of SR 139 and U.S. Route 2 is notorious for being one of the most dangerous intersections in central Maine. SR 139 then heads south and joins SR 104 for a 2.78 mile concurrency, during which it intersects with SR 23, followed by an interchange with Interstate 95. The section of SR 139 between U.S. Route 2 in Norridgewock and Interstate 95 in Fairfield is often used as a bypass of U.S Route 2 through Skowhegan. From the interchange with Interstate 95, as it heads east there is a 0.22 concurrency with U.S. Route 201 in Fairfield and then a 2.23 mile concurrency with SR 11 and SR 100 in Benton. SR 139 continues on to have a 0.18 mile concurrency with U.S. Route 202 and SR 9 before once more being without concurrent routes for 0.69 miles in Unity and then begins a 3.5 mile concurrency with SR 220 in Thorndike. SR 139 intersects SR 203 at its northern terminus and then SR 7 as it continues through Brooks. It then continues into Monroe, where it intersects SR 141 at SR 141's northern terminus. From there, SR 139 has a 1.67 mile concurrency with SR 69 and reaches its western terminus at US Route 1A in Winterport.[2]
