Home		Route 100 Termini The southern terminus of SR 100 is at US 1 and I-295 in Portland, at the corner of Forest Avenue and Park Avenue. This is looking north on Forest Avenue approaching I-295. SR 100 itself starts just behind the camera. (Douglas Kerr, 6/28/03) The first northbound shield. (Dan Bryant, 1/28/07) A closer view, included mostly for the R2 Unit postal box behind the assembly. (Dan Bryant, 5/21/07) The END, a useless multiplex shared with US 302. (Dan Bryant, 5/21/07) Facing west on Portland Street, which becomes Park Avenue & US 1 south after the intersection. (Dan Bryant, 4/7/07) Eastbound Park Avenue (US 1 north) at High Street, the northern END of SR 77. The US 302 / SR 100 terminus is in the background, a block further away. (Dan Bryant, 1/20/07) The northern terminus of SR 100 is in Bangor, at the corner of Hammond and Main Streets. With only one small exception, 100 runs concurrently with other routes for the entire stretch from Portland to Bangor. END sign on eastbound Hammond Street. US 2 continues straight on State Street.
