Project Information

SR 302 - Key Peninsula Highway to Purdy Vicinity - Safety & Congestion


Jan. 2015

  • See the Olympic Region Weekly Construction and Traffic Update report for current impacts to traffic.
  • Construction began Aug. 2014.
  • The project was awarded to Tucci & Sons, Inc. July 2014.
  • Striping changes have been incorporated into the project (see details below) in an attempt to focus drivers on the roadway and encourage them to drive the speed limit. These changes have proven to be effective in numerous traffic studies.


Why is WSDOT improving safety and congestion on SR 302 between Key Peninsula Highway and SR 16?
This section of SR 302 experiences congestion at specific locations and a high rate of collisions. 

To reduce congestion and the potential for collisions, WSDOT is developing improvements for key locations such as the 118th intersection. 

These improvements include widening portions of the road, adding left-turn pockets, widening shoulders, increasing sight distance and access consolidation. Other improvements include removing some trees and other hazards within the right of way and constructing several emergency pullouts.

Restriping work will also occur, with the goal of helping motorists drive within the speed limit and helping them focus on the road. That restriping will include widening the edge stripe to up to 8 inches to increase lane visibility for drivers. The edge stripe will be widened on the lane side so the shoulder width will not be affected.

Crews will also widen the center line stripe up to 8 inches to provide the appearance of a more narrow road.  Numerous studies have shown that the illusion of a narrower road slows drivers and helps them drive within the speed limit.

WSDOT will install more guide posts at closer spacing in the wooded areas and through curves to better delineate the road and focus drivers' attention.

WSDOT will also increase reflective lane markers to help delineate the road's center line. 

After all this work is completed, WSDOT will monitor speeds to see if additional measures are needed. 

The End Result
Specific improvements at key locations will reduce congestion and improve safety by reducing the frequency and severity of collisions.

Project Benefits
Safety - Improved sight distance along the corridor, new turn pockets to facilitate left turns, emergency pullouts at key locations, and numerous changes to striping and lane delineators to encourage drivers to stay within their lane and drive within the speed limit.

Congestion - Improved traffic flow along the corridor.

What is the project timeline?

  • Construction is expected to begin August 2014.
  • The project is expected to be complete by fall 2014.
