AMES, Iowa – Nov. 12, 2025 – Learn about proposed improvements to I-380 in Johnson County south of, and including, the 120th Avenue interchange in Swisher and Shueyville.
Changes include:
- Pavement replacement.
- Widening from four to six lanes.
- Increasing paved shoulder widths.
- Reconfiguration of ramps and interchange access.
During construction two lanes of traffic in each direction will be maintained on I-380. However, lanes and shoulders will be narrowed and shifted into temporary configurations to facilitate these improvements. Ramps at the 120th interchange will close for up to four months during construction, which is is expected to start spring of 2030 and end fall of 2032.
