→State Route 203 (SR 203) is a Washington state highway in King and Snohomish counties. The 24.26-mile (39.04 km) route begins at an intersection with SR 202 in Fall City. The highway extends north past Carnation and Duvall to end at U.S. Route 2 (US 2) in Monroe. The roadway connects Fall City, Carnation, Duvall and Monroe, all located along the Snoqualmie River, which SR 203 roughly parallels.
The route originally was divided into four separate roads, Fall City–Carnation, Carnation–Duvall, Duvall–Monroe and Lewis Street. The first road to be paved, Lewis Street in Monroe, was completed in 1912; the roads were later combined to form Secondary State Highway 15B (SSH 15B) in 1937. SSH 15B was later renumbered to SR 203 in 1964 during the highway renumbering. The routing of SR 203 was suggested as a new freeway in the 1990s and 2000s.
Route description
State Route 203 (SR 203) begins its 24.26 miles (39.04 km) of highway at an intersection with SR 202, a primarily west–east route, in Fall City.[2][3] There, the road is named the Fall City–Carnation Road and travels northwest, paralleling the former route of the Monroe–Tanner route operated by the Chicago, Milwaukee, St. Paul and Pacific Railroad.[4] After bridging the Rutherford Slough twice, the route travels closer to the shoreline of the Snoqualmie River.[5] SR 203 runs north past Northeast Tolt Hill Road to cross the Tolt River into Carnation. Leaving Carnation, the highway becomes the Carnation–Duvall Road and intersects Carnation Farm Road before curving west to intersect Stillwater Hill Road. Eventually, the roadway continues the original northern route past the 124th Street roundabout into Duvall.[6] In Duvall, SR 203 intersects the Woodinville–Duvall Road and Cherry Valley Road before curving along the Snoqualmie River shoreline into Snohomish County. After leaving Duvall and King County, SR 203 becomes the Duvall–Monroe Road and travels north to cross the Skykomish River and enter Monroe as Lewis Street. In Monroe, the highway parallels Woods Creek and intersects Main Street near the Monroe Greyhound Lines station. After Main Street, the road crosses the BNSF Railway Everett–Spokane line and ends at an intersection with U.S. Route 2 (US 2) and Chain Lake Road.[3][5] South of the US 2 intersection, an estimated 15,000 motorists used Lewis Street daily in 2007 based on average annual daily traffic (AADT) data collected by the Washington State Department of Transportation.[7]
Despite running parallel to Interstate 5 relatively close to Seattle, the highway is rural in nature and only two lanes wide for its entire length. Failed proposals to build a bypass freeway called Interstate 605 would have changed it to a freeway.
History
SR 203 was originally four roads that linked each other and their communities, Fall City, Carnation, Duvall and Monroe, named Fall City–Carnation Road, Carnation–Duvall Road, Duvall–Monroe Road and Lewis Street, respectively; these names are still used to identify the route.[3] Lewis Street became the first portion of the highway to be paved when the City of Monroe improved it in 1912.[8] The roads paralleled the former Monroe–Tanner route of the Chicago, Milwaukee, St. Paul and Pacific Railroad.[4] All four roadways were later combined to form Secondary State Highway 15B (SSH 15B) in 1937, during the creation of the Primary and secondary highway system.[9] The Washington State Legislature renumbered and changed the system in 1964 and SSH 15B became SR 203.[10] The highway has changed very little since then.
In 1998, the Washington State Legislature ordered a $500,000 study to investigate the benefits of constructing the proposed Interstate 605 north to Everett through the Snoqualmie Valley.[11] The plan was dropped as the study found that on average only five minutes would be saved over current routes.[12] In 2002, Bellevue Square owner Kemper Freeman, Jr. made his support known for a new freeway linking Snohomish County via the Snoqualmie Valley.[13] Another $500,000 study was ordered in 2003 by the legislature, creating a new commerce corridor to link Lewis County in the south to the Canadian border in the north.[14] However the study showed that a highway existing north of I-90 was not economically feasible. Had either proposal been built, it would have essentially replaced highway 203 with an interstate highway.[15]
Recently, smaller projects arranged by the Washington State Department of Transportation (WSDOT) have helped improve traffic on SR 203. Completed in 2004, a roundabout was constructed at the NE 124th Street intersection, located south of Duvall.[16][17]
