I-82 - South Union Gap Interchange Improvements


Fall 2015

  • This project is funded by the 2015 Connecting Washington Transportation Revenue Package.
  • Construction is scheduled to begin spring 2019.


Why is WSDOT Improving this interchange?
The existing interchange provides partial access to south Union Gap. Eastbound drivers on I-82 are currently unable to access south Union Gap and drivers in south Union Gap are unable to access westbound I-82. 

The End Result
Two additional ramps will be constructed at the South Union Gap interchange to provide the missing westbound on-ramp from south Union Gap to I-82 and the eastbound off-ramp from I-82 to north Union Gap. The reconstructed interchange will accomodate a direct connection to the proposed east-west Beltway Connector, and reduce the number of vehicles using the Valley Mall Boulevard interchange. Improved connections to I-82 will promote economic growth and development for the cities of Union Gap and Yakima.

Project Benefits

  • Economic Vitality. Local community and business leaders targeted improving this interchange and the Valley Mall Blvd interchange as top priorities for economic growth and vitality. Improved freeway access will open up new areas for development and ease congestion for the existing areas.
  • Safety. Improving capacity for the interchanges and providing more efficient connections to the local road system will improve traffic flow, lessen conflicts, and improve safety for this busy area.

What is the project timeline?
Construction is scheduled to begin spring of 2019.
