Route 490, also known as Stephenville Access Road and Katarina Roxon Way, is a 18.7-kilometre-long (11.6 mi) north–south highway on the western coast of Newfoundland in the Canadian province of Newfoundland and Labrador.

This is the only example of a road concurrency in the entire province of Newfoundland and Labrador.

They head north along the coastline to have an intersection with a local road leading to Mattis Point before crossing a bridge over an inlet to enter the town of Stephenville Crossing.

Route 490 now leaves town and winds its way northwest through rural hilly terrain for several kilometres to enter the Stephenville town limits and pass by the site of the former Ernest Harmon Air Force Base.

The highway now passes through wooded areas for a few kilometres before making a sharp right turn at an intersection with Minnesota Drive.
