The Iowa Department of Transportation is nearing completion of its I-380 widening project, with southbound traffic at the Highway 30 interchange now continuing straight onto three widened lanes. The project is part of a broader effort to rebuild and widen I-380 north and southbound lanes.
Why it matters
Pavement and bridges in the worked stretch are over 50 years old, and the rebuild addresses aging infrastructure for drivers across Iowa. Continued construction affects travelers using the corridor through the state.
The Iowa Department of Transportation projects $1.2 million in operations and maintenance savings over 20 years from the enhancements. The north segment construction is estimated to finish within the next three months, though the full scope of remaining median and roadside work is not detailed.
The players
Iowa Department of Transportation
The state agency responsible for maintaining and improving Iowa's highway network, including the I-380 widening project.
The details
Southbound lanes were rerouted to continue straight onto three widened lanes at the Highway 30 interchange, and the southbound rest stop is closed. Temporary overnight ramp closures may occur in both segments, and the northbound stretch of the north segment is not yet in its final configuration.
Timeline
Mid-December 2026: Southbound rest stop expected to reopen.
Within the next three months: North segment construction estimated to finish.
2030: Work on the segment from north of Swan Lake Road to near 120th Street expected to begin.
Home Stretch
The I-380 rebuild extends the Iowa Department of Transportation's multi-year program to replace aging pavement and bridges that are over 50 years old. Remaining segments from north of Swan Lake Road to near 120th Street are not expected to begin until 2030.
Drivers using I-380 should expect temporary overnight ramp closures in both segments and plan for the closed southbound rest stop until its expected mid-December reopening. Southbound traffic at Highway 30 now continues straight onto three lanes without crossing the highway.
The takeaway
Long-term pavement renewal on aging interstates often proceeds in staged segments, so drivers should watch for shifting lane configurations across multiple years. The Iowa Department of Transportation projects that these enhancements will reduce operations and maintenance costs over the next two decades.
What happens next
Southbound rest stop is expected to reopen in mid-December 2026, and north segment construction is estimated to finish within the next three months.
