Work is expected to begin today on a $411,730 project to construct an uphill passing lane on eastbound U.S. Highway 101 near Blyn.
Washington State Department of Transportation officials announced the roadwork near Chicken Coop Road could be completed in late May.
Officials say the work will improve traffic flow and increase safety by providing an additional lane for safe passage of slow moving vehicles on the uphill climb.
During construction, the highway will be limited to alternating one-way traffic, officials say.
