State Route 900 Mileposts 20.09 to 21.64 
 SR 900/SE 78th St Vic to I-90 Vic - Widening and HOV
This section of SR 900 in Issaquah is severely congested due to heavy traffic volumes and major commercial development in the surrounding area. During morning and afternoon peak periods traffic backs up onto the I-90 off ramp and nearby city streets. Buses serving the Newport Park and Ride lot are trapped in this congestion. This section of SR 900 also contains a high accident location. Two culverts have been identified as barriers to fish passage. To increase roadway capacity and improve traffic operations. SR 900 will be widened by one lane in each direction from SE 78th Street to I-90. HOV lanes will be constructed between the Park and Ride lot and I-90. Traffic signal improvements, including bus priority, will be provided. Two bridges will be widened and fish passage will be restored to two culverts.
