Updated October 24, 11:45 am:
E. 7th Street is now open between 1st Avenue and Quarry Road. This provides secondary access to the Iowa River Landing.

Updated October 15, 2019, 1:45 pm:

The following changes were made to traffic control on E. 9th Street to aid traffic flow and reduce traffic delays during construction:

  1. Re-opened the second westbound lane from 1st Avenue back to Ponseti Way to separate the westbound right and thru/left turn lanes. 
  2. Modified the 1st Avenue & E. 9th Street traffic signal to run the eastbound (Kum & Go side) and westbound (Iowa River Landing side) movements separate from each other. This allows westbound drivers exiting the Iowa River Landing to have a free-flow left turn onto southbound 1st Avenue.
  3. Increased the amount of green light time given to the westbound E. 9th Street movement exiting the Iowa River Landing. This will be monitored closely to avoid 1st Avenue backups into the I-80 ramps.
  4. Work is underway to pave the missing section of E. 7th Street so E. 7th Street can fully re-open between 1st Avenue and Quarry Road for the first time since June 2017. The E. 7th Street connection was expected to be available before starting the E. 9th Street project, but the wet September and early October stalled progress.  

The Engineering, Streets, and Police Departments will continue to monitor traffic in the afternoon and early evening.  

Beginning Monday morning, October 14, 2019, work will begin on the E. 9th Street Improvements between 1st Avenue and Quarry Road with the installation of traffic control devices. Construction activity will begin on Tuesday, October 15.   

About the Project
This project will enhance the E. 9th Street corridor with the addition of landscaped center medians, new north-south crosswalks, curb bump outs to establish parallel parking areas and shorten crosswalk distances, completion of the brick paver streetscape along the south side of E. 9th Street, and conversion of the E. 9th Street & E. 2nd Avenue intersection into a four-leg roundabout. The project will be constructed in two phases. 

Construction Phases
Phase 1 construction will run from October 14 to November 22, 2019. Work includes: 

  • New raised center medians west of E. 2nd Avenue
  • Portions of new north-south crosswalks along E. 9th Street
  • New driveway access for the east side of Xtream Arena that will be shared with the Johnson County Historical Society Museum and the Antique Car Museum of Iowa

During Phase 1, E. 9th Street will be reduced to one lane in each direction with no on-street parking allowed.  Traffic will run head-to-head on the north half of E. 9th Street between Ponseti Way and Quarry Road.  A new STOP sign will be installed on westbound E. 9th Street at Ponseti Way to make the eastbound left turn and through movements free-flow to minimize the chance of traffic backing up into 1st Avenue. 

Phase 1 construction is to be complete by November 22, 2019, and then all lanes will be open until April 1, 2020, when Phase 2 construction begins.  Phase 2 will complete the roundabout at E. 9th Street & E. 2nd Avenue and all remaining work along E. 9th Street by July 22, 2020.
