Since the State Environmental Study (SES) was released in March 2018, UDOT has hired a Designer-Contractor team, Oak Hills Constructors, to help with the design effort. Together, UDOT and Oak Hills Constructors have been reviewing and refining designs at interchanges, cross-streets, frontage roads, and other areas to look for ways to optimize the SES concept design and further reduce impacts and costs where feasible. More in-depth investigation has also taken place to locate utilities; adjust elevations, curves, and widths; and determine optimal designs for interchanges and other features. This process, known as Progressive Design-Build , allows for public input, contractor expertise and cost to be assessed and incorporated into the project design earlier than other delivery methods. This will help the project team design and build the right project for the area.
The project team shared the updated design with the public at an in-person open house and online in May 2019. You can view the open house materials here and drawings of the interchanges and bridges below.
