Pioneer Crossing Flex Lanes (Redwood Road to I-15)

UDOT is converting shoulders and the center median of Pioneer Crossing into reversible Flex Lanes, adding lanes so the Mill Pond Road-to-I-15 stretch has four lanes each direction, adding a westbound lane from Redwood Road to just west of Mountain View Corridor and a new signal at Medical Drive, and lengthening turn pockets. A new lane opened in each direction May 3, 2026; storm drain, pavement and bridge-deck work wrapped up in summer 2026. Remaining work includes 2300 West utility relocation and turn lanes (through late 2026), overnight lane and side-street closures, and Flex Lane signal activation in late 2026. UDOT says rush-hour commuters will save more than six minutes.
