Last week, the Federal Highway Administration cleared the last procedural step for construction of an interchange at I-35/80 and 100th Street in Urbandale, The Des Moines Register reports. It’s the second interchange in the area to be built after initial construction of I-35/80 in the late 1950s — an exit at 86th Street opened in 1994.
When the exit opens in 2018, it will provide some relief from the IA 141 interchange. That exit is going to get a flyover ramp (with closure of the inner loops) and two ramps will be added at Meredith Drive. However, there will still be stoplights on 141 between 35/80 and the IA 44 exit.
