Coast makes it very difficult to establish routes through the area. State Route 1, California's Pacific Coast Highway, was originally planned to continue up the coast through the region. In 1984, admitting that such construction was not feasible, Caltrans re-routed the northern segment of Highway 1 from Rockport to Leggett and renumbered the portion that was built from Ferndale to Fernbridge as State Route 211. Without any major highways or county thoroughfares in the area, the secluded communities within the Lost Coast are only accessible by land via small mountain roads. Mattole Road runs south from Ferndale to Petrolia, while Shelter Cove Rd. and Briceland Thorn Rd. form the main route connecting Shelter Cove with US 101 to the east. Shelter Cove Airport in Shelter Cove is a small public airport with only one runway, making it possible to fly in when weather permits. Communities right on the coast are also accessible by boat.
