The U.S. 30/67 corridor through Clinton will have a new traffic signal by late summer.
The city plans to add a traffic signal to the intersection of Harrison Drive and the highway due to recent changes in surrounding roads that have increased the potential for an accident to occur.
According to city engineer Jason Craft, drivers headed to business on the south side of the highway previously used a gravel path along the Union Pacific railway that runs below the highway. However, the UP closed access to drivers, which it has the authority to do, moving the vehicular traffic to use Harrison Drive. The amount of truck traffic passing through the intersection has increased also, making the need for a signal greater.
“With the limited sight, limited gaps in traffic, it’s really not safe to make a left hand turn there at all, but especially from the south,” Craft said.
The city received Urban-State Traffic Engineering Program funds from the Iowa Department of Transportation to complete the project. The city will be responsible for funding $90,000 while the state will pitch in $110,000. The city will bond for its portion of the project.
In order to secure the funding, the city submitted engineering documents to the state. While Craft said not many accidents have occurred at the intersection, the city would like to take a proactive approach to improving safety rather than a reactive one.
“We see the potential for accidents based on increased traffic volume and changes to that intersection,” Craft said.
The project will go out for bid in April and likely be complete by late summer.
Once the signal is in place, the city will then coordinate all signals from the intersection of U.S. 67 to South 14th Street in order to improve the traffic flow along the highway.
“It will improve the efficiency and safety not only at that intersection, but in the entire corridor,” Craft said.
