It begins at an intersection with SR 149 in Strong and runs east for 18.51 miles (29.79 km) to U.S. Route 201A (US 201A) and SR 8 in Anson.

SR 234 heads due east on Norton Hill Road, passing to the south of Porter Lake and crossing into New Vineyard, where it becomes Lake Street and intersect SR 27 (New Vineyard Road).

SR 234 turns north onto SR 27 and the two routes run concurrently for two miles (3.2 km) before SR 234 turns east again onto Anson Valley Road towards the town of Anson in Somerset County.

In Anson, SR 234 briefly runs along the southern bank of the Carrabassett River before terminating in North Anson at US 201A / SR 8 near their intersection with SR 16 and the confluence of the Carrabassett and Kennebec rivers.

However, state route logs[1] do not show this concurrency.
