State highway in Washington, United States

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 mile (4 km) east from [[Washington State Route 99 past [[Interstate 5 in Washington (I 5) and ends at [[Washington State Route 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 (Washington) from 1937 until 1964 and later [[Washington State Route 513 from 1964 until 1991.

State Route 523 (SR 523) begins at an intersection with [[Washington State Route 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. After the I 5 interchange, the road forms the northern boundary of the Jackson Park Golf Course and later continues to [[Washington State Route 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 annual average daily traffic (AADT) data collected by the Washington State Department of Transportation.

145th Street was paved by the King County government between 1934 and 1935. The Washington State Legislature first established a state maintained highway on a section of present day SR 523 in 1937, with the establishment of [[Secondary State Highway 1J (Washington) (SSH 1J), which ran from Downtown Seattle to [[Primary State Highway 1 (Washington) (PSH 1) in North Seattle, via the current 0.05 mile (0 km) long section of SR 523 from I 5 to 5th Avenue Northeast. During the 1964 highway renumbering, SSH 1J became [[Washington State Route 513 and PSH 1 became I 5; the northern terminus of SR 513 became the current SR 523 / I 5 interchange. In 1991, the northern terminus of SR 513 was moved south to its current location, Magnuson Park and SR 523 was established.
