Kansas Avenue near Coralville to close for relocation as part of the I-80/I-380 Systems Interchange Project

Posted on: September 11, 2018

CEDAR RAPIDS, Iowa – Sept. 11, 2018 – Beginning Monday, Sept. 17, Kansas Avenue, near the Interstates 80 and 380 Systems Interchange will be closed (see map) to make room for a new directional ramp from eastbound I-80, south to U.S. 218. This closure is anticipated to last up to two months, weather permitting, according to the Iowa Department of Transportation’s District 6 Office.

Additional construction activities on the Systems Interchange project include grading work on westbound I-80 to northbound I-380 and eastbound I-80 to southbound U.S. 218. Traffic will shift to a temporary shoulder pavement during construction. This fall, the Iowa DOT will begin construction of the new eastbound I-80 to northbound I-380 flyover ramp. Temporary night closures are anticipated for the existing ramp. Travelers are encouraged to be aware of and follow posted directional signs.  

Project details

The I-80/I-380 Systems Interchange Project is a comprehensive redesign that will modernize the interchange and improve mobility and safety. The Iowa DOT is replacing the existing Systems Interchange with a higher capacity design that will benefit freight trucking, public and commuter traffic, and the rural agriculture and manufacturing economy. Today, this interchange experiences excessive congestion and safety concerns. The project will reconstruct the interchange and add lanes, allowing more vehicles to travel safely and smoothly through the area.
