View larger map (pdf 627 KB)
New inside HOV lanes between Lake Washington and 108th Avenue Northeast opened in September 2014. The lanes 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 SR 520 HOV lane operates as follows:
- West of I-405: Buses and carpools travel in the inside lane, with a 3-person minimum occupancy requirement for carpools – the same occupancy requirement as before project construction.
- East of I-405: Operations remain the same. Buses and carpools travel in the outside lane, with a 2-person minimum occupancy requirement for carpools.
