For most of August, drivers and pedestrians can expect Dubuque Street to close temporarily at approximately 11 a.m. and 6:30 p.m., Monday through Friday, for underground work.

However, as a contingency, crews may close the road at 2 p.m. should the 11 a.m. work need to be delayed. Workers will not stop traffic more than twice per day. 

The closures will take place between Terrell Mill Park, located just north of the Mayflower Residence Hall, and Church Street. Drivers should expect delays and queuing during the closures and are encouraged to take a different route. View a map to learn where flaggers will be stopping traffic. 

A horn will be heard before the road is closed. Flaggers will be on site to stop traffic during the work for approximately 5 to 15 minutes.

Underground rock is being split to allow for the installation of deep sanitary trunk sewer under the northbound lanes of Dubuque Street. People can expect these closures through at least August 23. 
Gateway Project: Underground rock splitting

The work is being done as part of the Iowa City Gateway Project, a flood mitigation project to raise Dubuque Street while elevating and replacing the Park Road Bridge.  

Work was supposed to begin Tues. Aug. 2, 2016 but delays pushed it back to 2 p.m., Wed. Aug. 3, 2016.  

A reminder, the Gateway Project timeline is fluid and subject to change. Updates will be communicated as they become available.
