Project news

• The new eastbound off-ramp and westbound on-ramp opened to traffic on Aug. 22, 2020.

Project description
This project completed 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. Before this project, the South Union Gap interchange lacked full connections to I-82 and US 97. The previous interchange provided a westbound off-ramp to I-82, which forced motorists to use the Valley Mall Boulevard interchange and increased congestion in the Valley Mall area. This project completed 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 improves access to and from I-82 and Union Gap, provides efficient connections to local roads, improves traffic flow, and eases congestion in the area. WSDOT's new interchange ramps link to Union Gap's Main Street and provides access to Union Gap's future Regional Beltway Connector project.
