To improve traffic flow and reduce congestion, UDOT is adding a southbound lane to I-15 between S.R. 201 and 12300 South and expanding 7200 South, west of the freeway. The I-15 Southbound project will use $180 million dollars in state funds, which accounts for the environmental study, design and construction. Work will include:
- Adding a lane to southbound I-15 between S.R. 201 and 12300 South in Salt Lake County.
- Widening 7200 South to three lanes in each direction from I-15 to Bingham Junction Boulevard in Midvale.
- Modifying the I-15 interchange at I-215 to improve traffic flow.
