1st Avenue Construction Begins Next Phase on April 24


Starting at 9:00 on Tuesday, April 24, the 1st Avenue Improvements from 6th Street to 9th Street will transition into Phase 2 – Stage 1. During this stage, 6th Street will close to traffic between 1st Avenue and the driveway to the Baymont Inn & Suites. Traffic on 1st Avenue will be reduced to one lane northbound and one lane southbound near the 6th Street intersection, and both lanes will be shifted east onto temporary pavement. Phase 2 – Stage 1 should be complete by July 25.

Construction will impact Coralville Transit routes. Please visit for the latest information.

Access to businesses along 1st Avenue will be maintained for the duration of the 1st Avenue construction. During Phase 2 – Stage 1, the Baymont Inn & Suites will remain accessible using their southerly driveway at the intersection of 5th Street Place and 2nd Avenue (shared driveway with Burger King). Pedestrian access will be maintained along 1st Avenue through temporary surfacing and channelizing barriers. Drivers should expect delays and please drive carefully in work zones! 

With both northbound and southbound 1st Avenue reduced to one lane in the work zone, we are asking drivers to use both available lanes up to the point where the lane reduction occurs and then take turns merging, also referred to as zipper merging. Visit

The 1st Avenue improvements will be substantially complete this December and will feature:

  • Four through lanes and a continuous center turn lane
  • 10 foot wide sidewalks on both sides of 1st Avenue
  • Upgraded traffic signals at the E. 7th Street intersection
  • New four-leg intersection with traffic signals at 6th Street, with the fourth leg providing a future connection to E. 2nd Avenue in the Iowa  River Landing
  • New public utilities (storm sewer, sanitary sewer, and water main)
  • New roadway lighting and streetscaping
