Why is WSDOT
enhancing the Eastside transit and HOV system?
SR 520 is a busy regional corridor that connects key Eastside communities, including Bellevue, Kirkland and Redmond. Population and employment have steadily grown in these communities over the past several years, leading to increased traffic and transit demand.
This rise in congestion – and a roadway designed for the 1960s – has led to frustrating commutes and unreliable transit travel times.
The End Result
The Eastside Transit and HOV Project will complete and improve the 8.8-mile HOV system from Evergreen Point Road to the SR 202 interchange.
The improved six-lane corridor will include two general-purpose lanes and one transit/HOV lane in each direction.
New inside HOV lanes west of 108th Avenue Northeast will align with new median transit stops and direct-access ramps for carpools and buses. The existing outside HOV lanes east of I-405 will remain in place until traffic patterns and transportation planning efforts show a change is needed.
The Eastside Transit and HOV Project will provide transit service and mobility improvements along with environmental and community enhancements.
Planned Eastside transit service and mobility improvements:
- Regional bicycle and pedestrian path.
- Direct-access ramp to 108th Avenue NE for carpools and transit.
- Wider, safer shoulders.
- A transit/HOV lane through the entire Eastside corridor.
- Improvement of the Evergreen Point Road Park and Ride.
- Median transit stops at Evergreen Point Road and 92nd Avenue NE.
Environmental and community enhancements
- Fish habitat improvements.
- Noise reduction techniques.
- Stormwater treatment and detention facilities between Evergreen Point Road and 108th Avenue NE.
- New lids at Evergreen Point Road, 84th Avenue NE and 92nd Avenue NE.
