UDOT project teams use innovative solutions to reduce the inconvenience and traffic delay caused by road construction.
Examples of innovation in construction methods, phasing or delivery can be seen in several UDOT projects that recently received awards from the Utah Chapter of the American Concrete Pavement Association. The annual event provides a forum for transportation professionals to keep up with news about the concrete pavement industry.
Projects were chosen based on innovation and how team members worked to minimize inconvenience to road users while maintaining schedule, scope and budget. The judging committee looks for “innovative, unique projects with challenges,” says Mitzi McIntyre, Executive Director of the Utah Chapter.
The team from the 3500 South widening and BRT addition project show off a national award.
The awards were presented at ACPA’s Concrete Workshop in Salt Lake City. Here’s a list of the winning projects along with a few of the innovative solutions that were employed:
3500 South, Bangerter Highway to 2700 West widening – This busy travel and business corridor was widened from two to three lanes in each direction with a dedicated center-running BRT lane for the Utah Transit Authority. A moveable concrete barrier was used to maintain traffic flow through the construction zone – a first for a UDOT urban/non-freeway project. Work was completed 8 months ahead of schedule.
The 3500 South project won Gold in the National Excellence in Concrete Paving Awards.
I-15 EXPRESSLink – This Design-Build project added an Express Lane, rebuilt general purpose lanes, replaced bridges and added ramp improvements between Salt Lake and Davis Counties.
To limit travel delay, traffic was shifted to one side of the freeway
New concrete on the EXPRESSLink, better known at UDOT as the Beck Street project.
while the other side was constructed, and a movable barrier was used to keep three lanes of traffic moving in the peak direction. EXPRESSLink was completed three months ahead of schedule.
Riverdale Road widening – A five lane roadway was expanded into a seven lane arterial that connects four cities with I-15 and I-84. More than 47,000 vehicles travel this busy corridor daily to access freeways and a business district.
Project success hinged on keeping business owners informed and keeping the project on schedule. To accommodate busy winter road use, a construction hiatus took place between mid December and January 1. Even with the break, the project was completed 24 days ahead of schedule.
Bangerter Highway CFI at4700 South and 5400 South – Two innovative intersections were added to help traffic flow more efficiently.
To minimize construction impacts, crews worked in confined areas and reconfigured traffic control several times a day to not impede peak traffic flow. Precast concrete panels were used in some locations to avoid long lane closures.

I-80 Airport ramp Concrete pavement restoration – Most work was completed at night to limit inconvenience to road users. Access to the airport was maintained at all hours. The project was completed in 32 days, eight days ahead of schedule.
Syracuse Road widening – The original project scope called for using asphalt pavement. Using CMGC, an innovative contracting and delivery approach, UDOT determined that using Portland cement concrete pavement would not only provide longer design life, but also save over $1 million.
