Map showing interstate ramp closure


If you are traveling on First Avenue in Coralville and want to head west on Interstate 80 at the 242 exit beginning April 2, be aware of a detour that will add extra time to your trip, according to the Iowa Department of Transportation.

The westbound I-80 on-ramp will close for reconstruction and traffic will be detoured east on I-80 to Dubuque Street/exit 244. From there, a left turn will route traffic onto I-80 heading west.

The detour is expected to be in place until mid-June.

Also on April 2, the fully completed eastbound I-80 off ramp to First Avenue will open to traffic.

The Iowa DOT is reconstructing the interchange at I-80 exit 242 and First Avenue with a diverging diamond interchange. Major construction began in March 2023, and reduces First Avenue to one lane in each direction over I-80.

As of February, the project was 60% complete and on track for completion by the end of 2024, according to the Iowa DOT.
