I-380 Widening and Improvement Project in Johnson County

planned

The project involves improvements on I-380 from the Swisher and Shueyville exit south to Swan Lake Road in North Liberty. The scope includes widening the highway from four to six lanes, replacing pavement, widening shoulders, and reconfiguring ramps and interchange access. During construction, two lanes of traffic in each direction will remain open, with ramps at the exit closing for up to four months.
