Route 239 begins in
Lockston at an intersection with
Route 230 (Bonavista Peninsula Highway/Discovery Trail) and it immediately passes south through the community. The highway leaves Lockston and winds its way south along the coastline to have an intersection with a local road leading to
Trinity before passing through
Goose Cove and
Dunfield. Route 239 winds its way more inland through hilly terrain for several kilometres, where it passes through
Trouty, before coming to a fork in the road, with a local road leading to Old Bonaventure (
Route 239-15), and Route 239 continues south to
New Bonaventure, where the highway comes to a dead end at the town's harbour. ==Major intersections==
