Project news

• Here are the traffic revisions for Sept. 11 - Oct. 11: Westbound travelers on I-82 will not be able to access the south Union Gap off ramp (Exit 38). The I-82 Valley Mall Boulevard exit will remain open at all times as an alternate route. Northbound travelers on US 97 will be able to access south Union Gap. Northbound travelers on US 97 will follow detour signs to reconnect to westbound I-82.

Project description
This project will complete the interchange by constructing a westbound on-ramp and eastbound off-ramp between I-82 and Main Street to provide full access to Union Gap.

Delivery Method: Design - Build

I-82 / South Union Gap Interchange — Construct Ramps
Commercial and retail businesses continue moving into southern Yakima and Union Gap, resulting in additional traffic and increased congestion. Currently, the South Union Gap interchange lacks full connections to I-82 and US 97. The existing interchange provides a westbound off-ramp to I-82, which forces motorists to use the Valley Mall Boulevard interchange and increases congestion in the Valley Mall area. This project will complete the interchange by constructing a westbound on-ramp to I-82 and an eastbound off-ramp to provide full access to Union Gap.

Needs & benefits

This project will improve access to and from I-82 and Union Gap, provide efficient connections to local roads, improve traffic flow, and ease congestion in the area. WSDOT's new interchange ramps will link to Union Gap's Main Street and provide access to Union Gap's future Regional Beltway Connector project.

Construction impacts
During construction, the existing South Union Gap interchange ramps will remain open with minor delays to traffic. WSDOT will maintain access to businesses and residences throughout construction.
