Project Overview

Funding has been secured and all systems are go for design and construction of the new Dixie Drive interchange. The interchange will be formed by realigning Dixie Drive along the north side of the Southgate Golf Course and will connect to I-15 at the south end of the Dixie Center. It will be connected to the Bluff Street Interchange through a system of one-way collector/distributor roads. The designs for the new interchange and the arterial roads leading to and from the interchange are completed and construction began May 1, 2010..

This much needed project will dramatically improve the travel from Dixie Drive to I-15 and will also provide great benefits to the Dixie Convention Center in terms of accessibility and convenience. With the fast-growth predicted for the St. George, this project is also designed to relieve the congestion at the Bluff Street interchange as well as the Bloomington interchange.

The project is slated for completion by July 2012.
