I-82 Red Mountain interchange - vicinity map


Phase 1 improves the SR 224/225 intersection by eliminating two stop signs and building a roundabout. The I-82 interchange at Benton City serves most of the city's commercial activity, the Red Mountain American Viticultral Area (AVA), West Richland and rural areas of Benton County.

Phase 2 provides a new I-82 interchange and new connection to SR 224, east of Benton City. The proposed connection and interchange provide direct interstate access to and from develoopments in West Richland while improving emergency response times to the entire area.
