SR 503 begins concurrent to SR 500 at an intersection with Fourth Plain Boulevard in Orchards. The two highways travel north on the four-lane 117th Avenue through Orchards until SR 500 turns east onto Padden Parkway, while SR 503 continues north into rural Clark County, passing Prairie High School. The roadway bypasses Brush Prairie on its west side and crosses the Chelatchie Prairie Railroad, before it turns northeast onto 122nd Avenue.{{cite map |publisher=Washington State Department of Transportation |title=2011 Washington State Rail System |date=January 2012 |url=http://wsdot.wa.gov/NR/rdonlyres/FDBE2AB4-E504-4AC5-9E30-6A2CC4FAAD34/0/2011Ownership.pdf |format=PDF |access-date=February 8, 2013}} SR 503 enters Battle Ground as 10th Avenue and intersects the eastern terminus of SR 502 west of Battle Ground High School.{{cite web |date=December 31, 1992 |title=SR 502: Junction SR 503 |publisher=Washington State Department of Transportation |url=http://www.wsdot.wa.gov/mapsdata/tools/InterchangeViewer/pdf/SR502/502X007.pdf |access-date=February 8, 2013}} The highway crosses the East Fork Lewis River and leaves Battle Ground to pass Lewisville Park, listed on the National Register of Historic Places and located in Lewisville.{{cite web |date=June 6, 1986 |title=National Register of Historic Places: Weekly List of Actions |publisher=United States Department of the Interior, National Park Service |url=http://www.nps.gov/nr/listings/Weekly_Register_List_1986.pdf |archive-url=https://web.archive.org/web/20090514080559/http://www.nps.gov/nr/listings/Weekly_Register_List_1986.pdf |url-status=dead |archive-date=May 14, 2009 |page=70 |access-date=February 8, 2013}} SR 503 continues heading northeast into a heavily forested region of the Cascades foothills, toward Fargher Lake and Amboy.{{google maps |title=State Route 503 |url=https://maps.google.com/maps?saddr=NE+117th+Ave&daddr=45.9507715,-122.3662139+to:Lewis+River+Rd&hl=en&ll=45.779975,-122.634888&spn=0.512394,1.352692&sll=45.782595,-122.647845&sspn=0.512368,1.352692&geocode=FaDTuAIdS_-x-A%3BFTMnvQId-9a0-CnTfbyYFjKUVDG43W3DE9TyxQ%3BFbh1vAIdZxav-A&mra=dpe&mrsp=1&sz=10&via=1&t=m&z=10 |access-date=February 8, 2013}}

Every year, the Washington State Department of Transportation (WSDOT) conducts a series of surveys on its highways in the state to measure traffic volume. This is expressed in terms of annual average daily traffic (AADT), which is a measure of traffic volume for any average day of the year. In 2011, WSDOT calculated that the busiest section of the highway was the SR 500 concurrency in Orchards, serving 34,000 vehicles, while the least busiest section was at the western terminus of SR 503 Spur east of Yale, serving 720 vehicles.{{cite web |author=Staff |year=2011 |title=2011 Annual Traffic Report |publisher=Washington State Department of Transportation |url=http://www.wsdot.wa.gov/mapsdata/travel/pdf/Annual_Traffic_Report_2011.pdf |pages=185–187 |access-date=February 8, 2013 |archive-date=June 13, 2013 |archive-url=https://web.archive.org/web/20130613043942/http://www.wsdot.wa.gov/mapsdata/travel/pdf/Annual_Traffic_Report_2011.pdf |url-status=dead }} SR 503 between Orchards and Battle Ground is designated as part of the National Highway System,{{cite map |publisher=Federal Highway Administration |title=National Highway System: Portland, OR--WA |url=https://www.fhwa.dot.gov/planning/national_highway_system/nhs_maps/oregon/portland_or.pdf |date=October 1, 2012 |access-date=February 8, 2013}} which includes roadways important to the national economy, defense, and mobility.{{cite web |title=What is the National Highway System? |url=https://www.fhwa.dot.gov/planning/national_highway_system/ |publisher=Federal Highway Administration |date=September 26, 2012 |access-date=February 8, 2013}}
