Interstate Highway 5 in Washington State is a 276.62 mile stretch of highway that runs South to North in the Western section of the state. In Washington State, it is often referred to as "I-5."  It is the main route between Portland, Oregon and Vancouver, British Columbia in Canada.

I-5's Southern most part in Washington State is in Vancouver and its northern most part is the border with Canada at Blaine, WA.  I-5 is a six lane highway.

Major cities along the I-5 include Bellingham, Blaine, Centralia, Chehalis, Everett, Kelso, Mount Vernon, Olympia, Renton, Seattle, Shoreline, Tacoma, Tumwater and Vancouver.

Proceeding North from Portland, Interstate-5 takes a driver on a bridge over the Columbia River to enter Washington State.  The Interstate is a very interesting one to travel with drivers passing through rural towns, forested land,  urban sprawl, major cities such as Olympia, Seattle and Everett and stunning views of Mount Rainier, Mount St. Helens, the Puget Sound, the Capitol Dome and the iconic Space Needle in Seattle along the way.

The most densely driven sections of Interstate-5 are from Seattle to Tacoma with a lot of commuter traffic traveling from the communities of Tukwila, Des Moines and Federal Way.
