Drilling work will block lanes and trail near SR 520

Publish Date

Sound Transit’s design team is preparing for construction of the light rail extension into downtown Redmond. Drill rig crews will be working at various locations along the alignments for the next several weeks. Some of the work will require lane or trail closures. Geotechnical exploration helps the design team determine how to build the structures that will support the light rail system. Work is scheduled to minimize traffic disruptions.

Upcoming drilling areas

  • Eastbound SR 520 in shoulders, bus lanes, and ramps between NE 40th Street and West Lake Sammamish Parkway at various times day and night.
  • NE 60th Street east of SR 520 to 156th Avenue NE in the bike lanes from 9 a.m. to 3 p.m.
  • Intersection of 154th Avenue NE and NE 59th Street with flaggers alternating traffic from 9 a.m. to 3 p.m.
  • Redmond Central Connector Trail between 164th Avenue NE and 170th Avenue NE. Trail users will be detoured around the closure via NE 76th Street around the clock for up to four weeks.
