State Route 35 (SR 35) runs the course of western Maine, from Kennebunk to Bethel. It passes through Oxford, Cumberland and York, Cumberland, and Oxford counties. It is known in its lower sections for both its unusually windy course as well as its notoriously poor paving, as a result of winter frost heaves. Its northern section leads to the famous ski resort, Sunday River. The route crosses the Presumpscot River and a well-preserved section of the Cumberland and Oxford Canal approximately one mile (1.6 km) west of U.S. Route 302 (US 302) in North Windham.
