SR 512 begins at a partial cloverleaf interchange with I-5 in Lakewood, a suburb of Tacoma in the Seattle metropolitan area. The interchange only uses three cloverleaf ramps, with turns from southbound I-5 to eastbound SR 512 allowed via a traffic signal; beyond the interchange, the highway continues west to an intersection with South Tacoma Way.{{cite web |date=July 22, 2015 |title=SR 5 – Exit 127: SR 512/South Tacoma Way |url=https://www.wsdot.wa.gov/mapsdata/tools/InterchangeViewer/pdf/SR005/005X127.pdf |work=Interchange Viewer |publisher=Washington State Department of Transportation |access-date=November 28, 2018 |archive-date=February 12, 2017 |archive-url=https://web.archive.org/web/20170212131021/https://www.wsdot.wa.gov/mapsdata/tools/InterchangeViewer/pdf/SR005/005X127.pdf |url-status=live }} The six-lane freeway travels southeast along the north side of Joint Base Lewis–McChord and intersects Steele Street before it enters the suburban Parkland area.
