State Route 48 (SR-48) is a highway completely within Salt Lake County in northern Utah that connects the Bingham Canyon Mine with I-15 and US-89. The route is laid on the entirety of the New Bingham Highway and portions of 7800 South, Redwood Road, and 7200 South. When the route was formed in 1927, it passed through the center of Midvale on Center Street. However, it was moved north onto 7200 South in 1965 to serve an exit of I-15.
