State Route 531 (SR 531) is a short state highway in Snohomish County, in the U.S. state of Washington. It extends convert|9.88|mi|km|2 from Wenberg State Park in the community of Lake Goodwin, east to SR 9 in southeast Arlington. SR 531 intersects Interstate 5 (I-5) and passes the Arlington Airport. The route serves as a connector from I-5 to SR 9, Smokey Point and Wenberg State Park.cite map |publisher=Google Maps |title=State Route 531 Overview Map |url=http://maps.google.com/maps?f=d&hl=en&geocode=14285895264413201861,48.136460,-122.281550&saddr=E+Lake+Goodwin+Rd+%4048.136460,+-122.281550&daddr=48.151636,-122.113273&mra=mi&mrsp=1,0&sz=17&doflg=ptm&sll=48.151357,-122.113026&sspn=0.00204,0.004206&ie=UTF8&ll=48.156467,-122.211227&spn=0.130547,0.269165&z=11 |year=2008 |cartography=Tele Atlas |accessdate=2008-07-23]

SR 531 was approved by the Washington State Legislature in 1991 along its current route. Since then, construction projects arranged by the Washington State Department of Transportation (WSDOT) have turned this small road into an arterial street.cite web |url=http://apps.leg.wa.gov/RCW/default.aspx?cite=47.17.757 |title=RCW 47.17.757 |accessdate = 2008-05-09| |author=Washington State Legislature] Even though SR 531 was approved by the Washington State Legislature and WSDOT in 1991, no signs went up until the law that made SR 531 took effect on April 1, 1992.

Route description

State Route 531 runs about convert|9.88|mi|km|2 from Wenberg State Park to State Route 9, south of Arlington. The route links the communities of Lake Goodwin, North Lakewood, also known as Lakewood, Smokey Point, and Edgecomb, and passes four schools in the Lakewood School District and one, Weston High School, in the Arlington School District. The road intersects four major arteries: Forty-Five Road, Interstate 5, Smokey Point Boulevard (formerly known as U.S. Route 99), and 67th Avenue before ending at SR 9. [cite map |publisher=Rand McNally |title=The Road Atlas |year=2008 |page=108 |section=D7 |isbn=0528939610] WSDOT has found that about 35,000 motorists utilize the road daily at the I-5 interchange based on average annual daily traffic (AADT) data.cite web |url=http://www.wsdot.wa.gov/mapsdata/tdo/PDF_and_ZIP_Files/Annual_Traffic_Report_2007.pdf |title=Washington Annual Average Daily Traffic Data |author=Washington State Department of Transportation |year=2007 |accessdate=2008-08-26]

Lake Goodwin to Smokey Point

Starting at Wenberg State Park, the route runs north along East Lake Goodwin Road until it intersects Lakewood Road. From there, SR 531 travels east along Lakewood Road around Lake Ki before reaching Forty-Five Road. Here, Lakewood Road becomes the main artery of North Lakewood and Smokey Point, 172nd Street. Continuing east, SR 531 intersects 11th Avenue.

At the intersection with 11th Avenue, SR 531 becomes the northern boundary of the Lakewood High School campus, the only high school in the Lakewood area. SR 531 continues east from 11th Avenue to 16th Drive. Soon thereafter, the road intersects 19th Drive, which connects the southeastern section of North Lakewood with SR 531. Continuing east across a double track, the highway intersects 27th Avenue, which connects the road with Lakewood Crossing, a shopping center in Lakewood. SR 531 then continues east to the interchange with I-5.

mokey Point to Edgecomb

After leaving the interchange with I-5 and North Lakewood, SR 531 goes east to Smokey Point Boulevard (formerly U.S. Route 99) in Smokey Point. The road then continues going east, passing Weston High School and Arlington Municipal Airport, before intersecting 67th Avenue, a major road from Marysville to Arlington. From 67th Avenue, SR 531 goes east to a suburban community known as Edgecomb. The road curves northeast and then southeast while on a hill. SR 531 then goes east past the Arlington Gun Range and Gleneagle (a large housing area) before ending at an intersection with SR 9.

The first road is East Lake Goodwin Road, which is part of SR 531 from the western end at Wenberg State Park to an intersection with Lakewood Road.

The third and final road is 172nd Street, which is part of SR 531 from the intersection with Forty-Five Road to the east end of SR 531 at an intersection with SR&nbspl9.

History

The whole route of the highway from East Lake Goodwin Road to current SR 9 has been known to exist earlier than 1911.cite map |publisher=United States Geological Survey |title=Topography map of Mount Vernon and Vincity |url=http://content.wsulibs.wsu.edu/cgi-bin/pview.exe?CISOROOT=/maps&CISOPTR=447&CISORESTMP=/qbuild/buildplate11.html&CISOVIEWTMP=/qbuild/buildplate12.html&CISOROWS=2&CISOCOLS=5&CISOCLICK=title:subjec:creato:date:type |edition=January 1911 |year=1911 |scale=1:125,000 |accessdate=2008-09-12] The route from East Lake Goodwin Road south to Wenberg State Park was not opened until after the park opened. Also, 172nd Street NE once extended from current SR 9 to the banks of the South Fork Stillaguamish River, which has since been removed.

SR 531 became a state highway in 1991, and the highway designation took effect on April 1, 1992. In 2006, WSDOT announced it would complete three more projects over about five years to improve SR 531. The first, to improve the bridge and interchange between I-5 and SR 531, began immediately. [cite web |url=http://www.wsdot.wa.gov/Projects/SR531/SmokeyPt/ |title=I-5/SR 531 Interchange Improvements |accessdate=2008-05-10 |author=Washington State Department of Transportation] It was partly finished in June 2006 and will be completed after a loop ramp is added in 2011. In August 2007, WSDOT completed a project to add sidewalks along SR 531 to the adjacent schools of the Lakewood School District. [cite web |url=http://www.wsdot.wa.gov/Projects/SR531/LakewoodSchoolsSidewalks/ |title=SR 531 Lakewood Schools Sidewalks | accessdate=2008-05-10 |author=Washington State Department of Transportation] The third project, adding the loop ramp, will start in 2009 and end in 2011.
