SR 520 - Eastside Project Design

View of the improved Eastside corridor
The improved Eastside corridor stretches from Evergreen Point Road in Medina to 108th Avenue Northeast in Bellevue.


Key features of the Eastside Transit and HOV Project

The Eastside Transit and HOV Project completed and improved the 2.3-mile HOV system from Evergreen Point Road in Medina to 108th Avenue Northeast in Bellevue.

The reconstructed corridor, expanded to six lanes, now has two general-purpose lanes and one transit/HOV lane in each direction.

Key features include:

  • A transit/HOV lane through all but a small segment of the Eastside corridor near I-405.
  • Median transit stops at Evergreen Point Road and 92nd Avenue NE that are ADA accessible.
  • Wider, safer shoulders.
  • Direct-access ramps at 108th Avenue NE for carpools and transit.
  • A regional bicycle and pedestrian path.
