Upcoming Traffic Revisions for the Columbia St 2-Way Transit Corridor Project on April 4

SDOT is advising travelers that Columbia Street will be reduced to one travel lane between 2nd and 3rd Avenues on Wednesday, April 4, between 9 a.m. and 3 p.m. as work on the Columbia St 2-way Transit Corridor Project continues.

This work is in partnership with King County Metro in preparation to convert Columbia St from a 1-way street to a 2-way transit pathway. This work includes complete street reconstruction to accommodate buses, new signal poles, and curb line changes. This work is weather-dependent and subject to change.

From 9 a.m. to 3 p.m. on April 4 travelers can expect:

  • Columbia St will be reduced to one travel lane between 1st and 2nd Avenues
  • Westbound Columbia St traffic will be rerouted between 2nd and 3rd Avenues
  • Signed detours will be in place
  • One traffic lane will be maintained around the work zone
  • Local access will be maintained
  • Temporary pedestrian detours between 1st and 2nd Avenues
  • There will No Parking or Loading Zones in the work zone during construction
  • Vehicles travelling on Columbia Street may experience delays near the work zone
  • Construction-related noise, dust, vibration, and concrete odor
