State Route 523 (SR 523, named 145th Street) is a short Washington state highway located on the city limits of Seattle, Shoreline and Lake Forest Park in King County. The road itself runs 2.45 miles (3.94 km) east from SR 99 past Interstate 5 (I-5) and ends at SR 522; the highway was first established in 1991, but the roadway from I-5 to 5th Avenue Northeast was once the northern section of Secondary State Highway 1J from 1937 until 1964 and later SR 513 from 1964 until 1991.
State Route 523 (SR 523) begins at an intersection with SR 99 and North 145th Street at the northern Seattle and southern Shoreline city limits; at the SR 99 intersection, the highway is named 145th Street. From its western terminus, the roadway travels east to 1st Avenue NE, where SR 523 becomes Northeast 145th Street, which the road keeps until its eastern terminus. The highway travels 0.20 miles (0.32 km) east to interchange with Interstate 5 (I-5), where the northbound ramps are accessed through nearby 5th Avenue Northeast. After the I-5 interchange, the road forms the northern boundary of the Jackson Park Golf Course and later continues to SR 522 at the northern Seattle, southern Shoreline and western Lake Forest Park city limits. The SR 523 / I-5 interchange was used by an estimated 28,000 motorists daily based on average annual daily traffic (AADT) data collected by the Washington State Department of Transportation.
