Interstate 5 North - Vancouver to Woodland

Interstate 5

The city of Vancouver was settled in 1825 when the Hudson's Bay company moved its northwest headquarters from Astoria, the town's name honors George Vancouver, a British ship captain who had visited the region in the late 1700s. Under the Hudson's Bay Company, Fort Vancouver was the center of fur trading in the Pacific Northwest. It became part of the Oregon Territory when the U.S. border was extended to the 49th parallel in 1849, and was officially incorporated as the city of Vancouver in 1857 (City of Vancouver, n.d.).

A three phase project aimed to relieve traffic congestion along the I-5 corridor between the Main Street interchange in Vancouver and the I-205 junction was completed in October 2006. Finished at that time was the $44.4 million third project widening Interstate 5 to three general travel lanes plus an auxiliary lane in each direction along a two mile stretch between NE 99th Street and NE 134th Street. Associated work also replaced the NE 129th Street overpass as well as the Salmon Creek/NE 117th Street bridges (WSDOT, 2008).

The first project built the NE 99th Street interchange and widened the associated section of I-5 in 1996. The second project expanded 2.3 miles of I-5 from 39th Street in Vancouver north to NE 99th Street. That construction wrapped up in early November 2002 (WSDOT, 2008).
