The project includes widening U.S. 101 through Seaside from Avenue A through Avenue K.  Widening the road will allow us to create a center turn lane, bike lanes, and sidewalks to improve mobility for all road users. 

The project will:
  • Install new center turn lane.
  • Improve bicycle and pedestrian facilities.
  • Install two rectangular rapid flashing beacon crosswalks.
  • Install new curb ramps to ADA standards.
  • Upgrade traffic signs.
  • Improve drainage.
  • Replace pavement and install new striping.​
When in construction the work will require brief lane closures with flagging.
