SR 520 - Eastside Project Design

Key features of the Eastside Transit and HOV Project

The Eastside Transit and HOV Project improved SR 520's 2.3-mile segment 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 improvements for the Eastside corridor include:

  • An inside transit/HOV lane through all but a small segment of the corridor near I-405.
  • Median transit stops at Evergreen Point Road and 92nd Avenue Northeast. The ADA-accessible stops allow buses to move more efficiently and safely into and out of the transit stations.
  • Wider, safer shoulders that allow disabled vehicles to park fully out of the highway's traffic lanes.
  • Direct-access ramps at 108th Avenue Northeast for carpools and transit.
  • The first leg of a regional bicycle and pedestrian path that eventually will extend between Seattle and Redmond.
  • Landscaped, community-connecting lids over the highway at Evergreen Point Road, 84th Avenue Northeast (pdf 4.5mb) and 92nd Avenue Northeast.
  • A new, improved Bellevue Way overpass (pdf 725kb).
