A conversion was also recently completed on First Avenue, between Bradford Drive and Highway 6.
The lane reconfiguration will allow for additional improvements like replacing traffic signals and adding paving for bike lanes. Along Mormon Trek, the new lanes would also add a northbound to eastbound right turn lane at the Benton Street intersection and new sidewalk ramps.
The Iowa Department of Transportation will help with the development of the project through Traffic Safety Improvement Program funding.
Research suggests significant safety benefits can be achieved through four-lane to three-lane conversion projects, including reduced crashes. The City selected Mormon Trek Boulevard for conversion as the volume of traffic does not necessitate the current number of lanes. The roadway also has several side street intersections, making it a good candidate for conversion. Pictured below are common crashes that occur on four-lane, two-way traffic roads.
The City hosted public meetings for the Mormon Trek project in June 2016. After those meetings, time was spent developing the design, and construction began in August 2018.
