Unforeseen issues delay reopening of 11th Avenue North/Industrial Road intersection

A series of significant challenges are hindering construction of the 11th Avenue North intersection, resulting in the continued closure of Industrial Road and Sugar Street. These unforeseen issues, combined with colder temperatures, could delay completion of the project until late winter/early spring. The city will continue to provide updates so the traveling public can stay informed.
The project was on schedule for completion in November until an underground boring drill hit a 6-inch diameter abandoned steel pipe about 9 feet under the Union Pacific Railroad (UPRR) tracks. UPRR was unaware that the pipe was under the tracks. Additional rock excavation is necessary to cut-out the steel pipe section before boring can continue.
Once the pipe issue is resolved, the contractor plans to work 24-7 to finish boring activities, but at best the work would be completed in mid-December. As a result, freezing weather could delay the asphalt overlay within the UPRR track area until weather is warmer. Asphalt must be placed when temperatures are well above freezing to set up properly.
Crews have had ongoing challenges boring water and stormwater pipes under five UPRR tracks due to severely deteriorated existing infrastructure and more than anticipated rock under the road surface. Previous surveys indicated rock was present 10 feet below the roadway but in reality, crews encountered rock less than 3 feet beneath the surface.  
“We are extremely disappointed to have to extend our construction schedule to deal with these issues. The city knows motorists are anxious for us to finish this project. We, too, want traffic flowing through the intersection again, and are doing our very best to accelerate the schedule,” said Michael Fuss, Public Works Director.
The cost of the project was originally estimated at $2 million. The additional coordination with UPRR, rock excavation, and pipe boring have increased the total cost of the project by approximately $250,000-$300,000. The city has been able to offset most of the extra cost through a $200,000 railroad safety grant through ITD Rail Safety Program.
Project updates will be posted on the city’s project webpage at If you have questions, please call 465-2221 or email
