  This project constructed a bypass for southbound SR 28 traffic to the west of the Grant Road intersection.  It also widened eastbound Grant Road to allow a triple left turn from southbound SR 28.

Complete September 2013

Construction began Sept. 6, 2011 and was complete Sept. 13, 2013.

Construction of the new concrete intersection at Grant Rd. and SR 28 began May 5 and opened to traffic on May 23.  (Watch a 2-1/2 minute time lapse movie of the 18 days of construction to build it.) Repaving of the asphalt bridge approaches and completion of the bicycle and pedestrian facilities continued into Sept.

This I-1 Highway Capital-Mobility Improvement project is located on SR 28 in Douglas County.

Why is WSDOT constructing this interchange improvement?

In 1997, the comprehensive Wenatchee Area Transportation Study (WATS) identified the need for more study of the congested SR 28/285 interchange area.  Increased traffic volumes and delays were, even then, causing the Grant Road intersection to exceed its capacity.  The Washington State Department of Transportation, Douglas County and the City of East Wenatchee sponsored the SR 28/285 Interchange Area Improvement Study to evaluate the community‚Äôs transportation needs and develop a specific plan.

That study was completed in December of 2002.  The recommended long term solution is a Single Point Urban Interchange (SPUI) at the intersection of SR 28/285 and Grant Road.  This underpass-type interchange would bring all ramps to a single signalized intersection above the highway.

In October of 2003, a value engineering team, comprised of members from WSDOT, Douglas County, the City of East Wenatchee, and the Wenatchee Valley Transportation Council reviewed the proposed design and looked for ways to refine it and reduce impacts to the local businesses and the traveling public.  The team recommended a plan to construct a SR 28 bypass for southbound traffic immediately, with construction of the SPUI as traffic volume increases in the future.

The End Result
This project constructed a two-lane, one-way bypass for southbound SR 28 traffic, from the off-ramp on the east side of the SR 285 Senator George Sellar Bridge connecting to SR 28 south of 3rd Street SE.  The original ramp for southbound SR 28 traffic to Grant Road was removed and that traffic now gets to Grant Road from the bypass by turning left between Fred Meyer and Hobby Lobby.  A third left turn lane from SR 28 to Grant Road and a third eastbound lane up Grant Road was also built. 

This is one of three projects in south Wenatchee designed to improve mobility and reduce collisions.  For more information on the three projects click here. (PDF) 

Project Benefits

  • Safety:  Reduces lane weaving movements from the intersection of SR 28 and Grant Road.
  • Congestion:  By removing southbound SR 28 traffic from the Grant Road intersection and placing it onto the bypass, traffic through the intersection is reduced.  By adding the third left turn lane up Grant Road, the signal has been optimized to move more traffic.
  • Environment:  The project alignment was developed to stay as far away from the Columbia River shoreline as feasible.  Walls were constructed to minimize impacts to native vegetation and sensitive natural areas. The new permanent storm water detention and treatment facilities were constructed to blend with the natural topography and landscape.
