Constructions for the Route 40 corridor project starts today

The project to update the Route 40 corridor is starting today in Ballard and Northgate.

The Seattle Department of Transportation’s (SDOT) Route 40 Transit Plus Multimodal Corridor Project is getting underway with preliminary work on NW Market St and 22nd Ave NW and 20th Ave NW and NW Leary Way. Crews are also going to start work on the Northgate portion at N 105th St and N Northgate Way and Aurora Ave N.

In Ballard, the project plans include improving sidewalks, curb ramps, and pedestrian crossings.

In Northgate, construction includes upgrading sidewalks, ADA-compliant curb ramps, and bus stop improvements. Eastbound lane restrictions are expected to begin July 1 during daytime hours on N 105th St/N Northgate Way.

SDOT says to expect the following during construction in these areas and throughout the rest of the project corridor:

What you can expect:

  • Temporary lane reductions
  • Temporary driveway closures
  • Temporary bus stop closures
  • Temporary parking restrictions
  • Temporary sidewalk detours
  • Temporary storage of construction supplies in the street  
  • Bus stop relocations
  • Drainage work: This involves digging trenches to help manage water flow.
  • Signal Pole Foundation Excavation: This work involves digging for the pole foundations prior to when we order custom signal poles which takes a while to build and to make sure we know there are no underground obstructions  
  • Trenching for conduit: This involves digging trenches to lay down pipes or cables underground.
  • Sidewalk curb bulb out: This involves making the curbs stick outward for safety or accessibility.
  • Mill and fill overlay: This is when the top layer of the road gets removed and replaced with new asphalt
