The Midvalley Highway involved 4.5 miles of roadway. The project included a new two-lane freeway, a new interchange at I-80, and a direct connection to SR-138 in the Tooele Valley.

The Midvalley Highway was a greenfield project. Due to the unique salty marsh ground in the area, over 1,000,000 tons of borrow material were trucked onto the project, and 220,000 cubic yards of material were brought onto the project to surcharge the structure areas. Since some areas settled as much as 30%, it was necessary mid-project to construct the two bridges, the interchange at I-80, and a cattle crossing.

The Midvalley Highway provides direct access to I-80 for those in western Tooele County and is expected to remove 15-20% of the traffic from SR-36 in the Lake Point area. That traffic reduction is equivalent to 6,000 to 8,000 vehicles per day. The traffic reduction is also expected to reduce delays southbound on SR-36 by 70%.

The project was completed during the pandemic challenges without force majeure and was delivered on time and under budget.
