SR-111 in

Interstate 215 in the city of

Route description
From SR-111 in Magna, the highway (known as 3500 South) runs due east with between one and four general-purpose lanes in each direction until its junction with Redwood Road (
SR-68), where it veers to the northeast before again straightening out to the east. Other than the west end, this portion is entirely within
West Valley City. The route passes through the former towns (now neighborhoods) of Hunter and Granger as well as West Valley City's modern downtown area near I-215 (which overlaps with historic Granger). The intersection with Bangerter Highway (
SR-154) was the first
continuous flow intersection built in Utah. At the intersection with 2700 West just west of I-215, the route crosses
