[edit] Route description

SR 900 begins at the intersection with Ryan Way at I-5 exit 157, near the southeast corner of Boeing Field. It heads south on Martin Luther King Jr. Way (formerly Empire Way), with ramps to and from I-5, before splitting from the alignment of I-5 and heading east into Renton (with a short section in Seattle). It heads into downtown Renton on Sunset Boulevard. At State Route 167, a one-way pair begins, with eastbound SR 900 on Third Street and westbound SR 900 on Second Street. At State Route 515, SR 900 heads northeast on Houser Way (eastbound) and Bronson Way (westbound), and after a block SR 900 east turns north on Mill Avenue to rejoin the westbound side on Bronson Way.

Just before Bronson Way crosses under I-405, SR 900 turns north along the west-side frontage road, Sunset Boulevard. Sunset crosses to the east side of I-405 and then turns east, taking SR 900 between the slopes of Cougar Mountain and Squak Mountain to its end at I-90 in Issaquah (though the name changes to Renton-Issaquah Road). Lake Sammamish State Park lies right across I-90 from the end of SR 900.

[edit] History

Before April 1, 1992, SR 900 continued west (compass north) along Martin Luther King, Jr. Way and Rainier Avenue to end at I-90 exit 3. The west end of SR 900 is now milepost 5.93 due to this truncation; the east end is milepost 21.64.
Before the Lake Washington Floating Bridge was built across Lake Washington in 1940, SR 900 was one of the major roads east from Seattle, taking US 10 and Primary State Highway 2 around the south side of the lake. It had been established by the legislature as a State Highway in 1909,[1] and PSH 2 was completed for through traffic in 1915 (the last section being east of SR 900, through Snoqualmie Pass).[2] The opening of the bridge in 1940 moved US 10/PSH 2 to the direct route, and the old alignment became Alternate US 10 and PSH 2 RE (for Renton). In 1955,[3] Alternate US 10 was dropped, and it became SR 900 in 1964.
