WSDOT Travel Advisory: State Route 520 bike trail to close daily in Redmond, April 16-18 and April 22-24

REDMOND – People using the State Route 520 bike trail should plan for daily closures between West Lake Sammamish Parkway Northeast in Redmond and 148th Avenue Northeast in Redmond from April 16-18 and April 22-24.

During the closure, WSDOT maintenance crews will resurface damaged sections of the bike trail and remove protruding tree roots that caused uneven surfaces. Root guards, which can be installed without closing the trail, will be placed at a later date to mitigate further disruption and pavement bulging from wayward tree roots.

The SR 520 trail closure details (8 a.m. to 4 p.m. each day):

  • Wednesday, April 16 and Tuesday, April 22: West Lake Sammamish Parkway Northeast to Northeast 51st Street.
  • Thursday, April 17 and Wednesday, April 23: Northeast 51st Street to Northeast 40th Street.
  • Friday, April 18 and Thursday, April 24: Northeast 40th Street to 148th Avenue Northeast.

The following are detours during the respective closures:

  • Wednesday, April 16 and Tuesday, April 22: From SR 520, southbound West Lake Sammamish Parkway Northeast to westbound Tosh Road, which becomes Northeast 51st Street.
  • Thursday, April 17 and Wednesday, April 23: From SR 520, westbound Northeast 51st Street to southbound 150th Avenue Northeast to eastbound Northeast 40th Street.
  • Thursday, April 17 and Wednesday, April 23: From SR 520, westbound Northeast 40th Street to southbound 150th Avenue Northeast to westbound Northeast 36th Street to southbound 148th Avenue Northeast.

WSDOT will continue to work with its local partners and adjacent businesses to prevent further tree root intrusion to prevent further damage to the trail.
