State Route 503 ( SRÃ, 503 ) is a 54.11 km (state-of-the-art) state road that serves Clark and Cowlitz areas in Washington state. The highway moves north from a short concurrency with SR 500 at Orchards via Battle Ground, east terminal SR 502, and community in rural Clark County before crossing the Lewis River at Yale Bridge. SR 503 cuts the spur route and turns west to align the Lewis River down into Woodland, where the highway ends at an intersection with Interstate 5 (I-5). This highway is part of the Lewis River Road, which was signed as State Road 15, from 1909 to 1919. The current route of SR 503 is divided between Highway 1 S (SSH 1) from Woodland to Battle Ground and SSH 1U from Battle Ground to the Garden in 1937, combined to form SR 503 during the re-establishment of the 1964 highway. The spur route, founded in 1991, traveled northeast to the Gifford Pinchot National Forest along Lake Yale, serving the Cougar community.

Route description
SR 503 starts simultaneously with the SR 500 at the intersection with Fourth Plain Boulevard on Orchards. These two highways travel north on Avenue 117 Avenue through Orchards to SR 500 heading east to Padden Parkway, while SR 503 continues north to the Clark County countryside, past the Prairie High School. The highway runs past Brush Prairie on its western side and crosses the Prairie Chelatchie Train, before turning northeast onto 122nd Avenue. SR 503 enters the Battle Ground as 10th Avenue and cuts the east end of SR 502 in the west Battle Ground High School. The highway crosses the East Fork of the Lewis River and leaves the Battle Ground to pass Lewisville Park, registered at the National Register of Historic Places and located in Lewisville. SR 503 continues to head northeast into the heavily wooded area at the foot of the Cascades, towards Fargher Lake and Amboy.
SR 503 turns east into the Fargher Lake Highway at Rock Creek and enters Amboy by following Chelatchie Creek towards Yale Lake. The highway runs north and crosses the Lewis River to Cowlitz County on the 532-foot (162 m) Yale Bridge. The one-track warren truss bridge, listed on the National Register of Historic Places, is located downstream from the Yale Dam on Yale Lake and upstream of Merwin Lake. SR 503 continues into Cowlitz County and turn west to Lewis River Road at the intersection with a spur route leading east to Skamania County. The highway moves southwest in the valley of the Lewis River and passes through the Yale and Ariel communities. SR 503 enters Woodland and turns south toward Goerig Street before ending at a diamond junction with the I-5 near the Lewis and Columbia River encounters.
Every year, the Washington State Department of Transport (WSDOT) conducts a series of highway surveys in the state to measure traffic volume. This is expressed in the average annual daily traffic (AADT), which is a measure of the volume of traffic for each day on average in a year. In 2011, WSDOT calculated that the busiest section on the highway was the SR-500 concurrency at Orchards, serving 34,000 vehicles, while the busiest part was in the west terminal SR 503 Ã, Spur east of Yale, serving 720 vehicles. SR 503 between Orchards and Battle Ground is defined as part of the National Highway System, which includes an important highway for national economy, defense and mobility.

History
SR 503 follows the State Road 15 route, established in 1909 as the Lewis River Road, travels east from Woodland to the county Skamania line at the Columbia National Forest. The Lewis River Road was removed from the state highway system in 1919 and transferred to Cowlitz County for maintenance. Clark and Cowlitz County contracted the Portland Bridge and Iron Company to build a bridge over the Lewis River in 1917 and the bridge was opened for traffic in September 1920 at a cost of $ 15,000. After the completion of Merwin Dam dam in 1931 causing water levels in the Lewis River to rise, the two districts completed a one-track warren truss bridge named Yale Bridge over the Lewis River the following year to serve the remote Yale and Yacolt communities.
During the construction of the primary and secondary state roads in 1937, State Road 15 was added back to the state highway system as part of SSH 1S, which took 57.60 miles (92.70 km) from Primary State Highway 1 (PSH 1 ) and the US. Route 99 (USÃ, 99) to SSH 1U at Battle Ground and turn west to end at PSH 1 and 99 north US Mount Vista. PSH 1U, also established in 1937, traveled 8.56 miles (13.78 km) south of SSH 1S at Battle Ground to SSH 8A in Orchards. The Yale Bridge was managed by Clark and Cowlitz County until the 1940s and had a wooden approximation range replaced by steel in 1958 under the care of the Department of Highways.
SR 503 was established in 1964 determination of road number and codified in 1970 as a substitute of SSH 1U and part of SSH 1S between Battle Ground and Woodland, while the remaining SSH 1S between Mount Vista and Battle Ground became SR 502. The highway in the river valley Lewis, between Woodland and Yale Bridge, was closed after the eruption of Mt. Helens on May 18, 1980 and reopened after the Yale Bridge was placed on the National Register of Historic Places in July 1982. The SR 503 propulsion route was added to the state highway system in 1991 as part of the original Lewis River Road between Yale and the Skamania county line at Gifford Pinchot National Forest. Between Orchards and Amboy, SR 503 is designated as "Lewisville Highway", serving the historic Lewisville Park.
Spur routes
SRÃ, 503 Spur, known locally as Lewis River Road, embarked on a 8.42 mile (13.55 km) route at the crossing with SR 503 east of Yale and north of Yale Bridge. The highway moves northeast along Lake Yale through the Cowlitz County Forest area, past Yale Park and the Cougar community. SRÃ, 503 Spur veered east at Beaver Bay Park and ended shortly thereafter at Forest Route 90 in Skamania County south of Mt. Helens National Volcanic Monument and Gifford Pinchot National Forest. The Lewis River Road was part of State Road, 15 from 1909 to 1919 and re-established in 1991 as a spur route from SR 503. WSDOT conducted a series of surveys to measure traffic volume in terms of AADT and calculated that 650 to 1,300 vehicles per day using spur route in 2011.
