Lane Shifts and Ramp Openings on I-380 in Black Hawk County Begin Aug. 14 #iatraffic

Posted on: August 13, 2013

NEW HAMPTON, Iowa – Aug. 13, 2013 – Work on the northbound Interstate 380 reconstruction project in Black Hawk County requires moving traffic from the two-lane, two-way pattern in the southbound lanes to a divided highway traffic pattern using both the southbound and newly reconstructed northbound lanes beginning overnight Wednesday, Aug. 14, with the change completed by 6 a.m. Thursday, Aug. 15, weather permitting, according to the Iowa Department of Transportation’s New Hampton construction office.

The lane shifts will also involve closing the inside lanes of both north- and southbound I-380.

This change in traffic patterns will also allow the reopening of northbound I-380 on- and off-ramps at Black Hawk County Road V-49 (Raymond Road) and northbound I-380 off-ramp at River Forest Road. However, the northbound I-380 on-ramp at River Forest Road will remain closed until mid-September.

Motorists are advised to find alternate travel routes, if possible, because only one lane will be open in each direction and traffic backups are still very possible, especially during peak travel times.

The entire I-380 reconstruction project is expected to be completed by mid-September, weather permitting.

The Iowa DOT reminds motorists to drive with caution, obey posted speed limit and other signs in the work area, and be aware that traffic fines for moving violations are at least double in work zones. As in all work zones, drivers should stay alert, allow ample space between vehicles and wear seat belts.

The Iowa DOT has developed a website at to provide ongoing information related to the I-380 revitalization project. The site includes project details, corridor facts, a project timeline, emergency detour routes, and photos of the project area and construction activities. Information about the I-380 project is also available on Facebook at
