Map of ME-100, Maine, USA
The south end of State Route 100 is at I-295 Exit 6 in downtown Portland, the same place U.S. Route 302 ends. State Route 100's north end is at the intersection of Hammond Street, Main Street, State Street and Central Street in downtown Bangor; State Route 100 runs along Hammond Street with U.S. Route 2 (which continues across Main Street/Central Street onto State Street). This is also the east end of U.S. Route 202, which runs along Main Street. (State Street is one-way eastbound, so traffic on US 2 west uses Central Street.)
Concurrent routes
The majority of State Route 100 is concurrent with other routes:
The only part of State Route 100 that does not run along another route is between US 302 and State Route 26 in northern Portland, where it is alone on a small piece of Allen Avenue.
Alternate route
State Route 100A is a 5.2-mile (8.4 km) alternate of Maine State Route 100 running between the towns of Winslow and Benton.
Route 100A's alignment was formerly part of Maine State Route 32, before Route 32 was truncated in 1954 to end at Route 137 Business, near its intersection with US-201/Route 100 just south of Route 100A's current terminus. The old alignment, which connected to Route 100 at both ends, was redesignated as Route 100A (as a bypass of Route 100's alignment in Winslow and Benton). As such, Route 100A is a former alignment of Route 32, and not of its parent, Route 100.
