20th Street SE Corridor Improvement Project
(US 2 Trestle to S. Lake Stevens Rd.)
and SR9/20th St SE Project
10/1/09 Update:
Beginning Thursday night, October 8: 94th Dr. SE will be closed at 20th St. SE during construction of the north side of the corridor. The closure will last close to three months. Work includes lowering 94th Dr. SE at 20th St. SE approximately three feet, building several retaining walls, and storm drainage.
Left turns from 20th St SE onto SR9 will be prohibited through May 2010. Detour routes will be posted.
Ongoing Traffic Impacts
Single lane closures and intermittent lane shifts are in effect on 20th Street SE to allow Snohomish County Public Works and various utility companies to work on a corridor improvement/road widening project between the SR 2 trestle and 106th Avenue SE.
Lane shifts will be allowed between 7:00 a.m. – 5:00 p.m.
Lane closures will be allowed between 9:00 a.m. and 3:00 p.m.
Drivers can expect bumpy roads and periodic delays of up to 15 minutes through the construction area and are advised to use alternate routes when possible. We apologize for the inconvenience as we work to remodel and improve 20th Street SE.
| Project Description
Vehicle and bicycle lanes, sidewalks and bus "pull-outs" are being added to 20th Street SE. New traffic signals will also be installed at several intersections. HOV lanes are planned between Cavalero Road and 91st Ave SE for westbound traffic during the morning commute. These changes are designed to improve traffic safety and travel time.
Snohomish County has also partnered with Community Transit to reduce traffic congestion. Learn about the incentive for trying a bus or vanpool at . . . Curb the Congestion

State Route 9 Snohomish County is managing the Washington State Department of Transportation's project to improve SR9 between 20th St SE and S. Lake Stevens Road. For more information about WSDOT's SR9 corridor improvement projects, visit the WSDOT project page |
