As I-80 enters the Iowa City area, the speed limit drops to . On the edge of Coralville is an interchange with US 218 and Iowa 27. This interchange is also the beginning of I-380, which heads north along US 218 and Iowa 27 towards Cedar Rapids and Waterloo. The I-80 / I-380 interchange was identified as the most likely location in Iowa for a semi-trailer truck to overturn. According to the American Transportation Research Institute, 30 trucks rolled over at the interchange during the 8-year study period. The Iowa DOT has plans to replace the cloverleaf interchange with a turbine interchange, but the project would not take place until around 2025.
