Excavators work along a section of Mount Angeles Road near the Olympic National Park visitor center on Thursday as part of a project to improve the Race Street corridor from Olympus Avenue to Eighth Street in Port Angeles. Phase one of the project, which will require occasional lane closures and detours, will include utility upgrades and safety improvements for pedestrians, bicyclists, vehicles and transit users. Later phases of the project will extend from Eighth Street to the Port Angeles waterfront.
