“State DOTs are overwhelmingly focused on innovative solutions to address the transportation issues of today and tomorrow, meeting challenges involving climate change, equity, resiliency, and safety,” said Jim Tymon, Executive Director of AASHTO. “The America’s Transportation Awards program shows just how they’re doing that. Whether on foot, in a vehicle, on two wheels, or by rail or transit, state DOTs are continuing to advance a safe, multimodal transportation system.”
Eighteen projects in the Mid America Association of State Transportation Officials (MAASTO) region were nominated by eight states for this year’s competition. The following two projects in the Midwest Contractor area were winners of the regional America’s Transportation Awards.
“I-74 over the Mississippi River is an important east-west link in the nation’s transportation network, carrying more than 45 percent of all traffic in the Quad Cities,” said Ahmad M. Afifeh, PE, Iowa DOT's I-74 Project Manager. “The 86-year-old bridge was narrow, lacked shoulders, and carried nearly double the amount of traffic it was built to accommodate, leading to major congestion and traffic delays. A new bridge was needed as part of a regional strategy to improve interstate travel. The growing region demanded not just any bridge, but a transformational asset that unifies the communities both symbolically and in other new, exciting ways. The new bridge brings travel on I-74 in the Quad Cities into the 21st century.”
The bridge has four lanes in each direction, a 14-foot-wide bike and pedestrian path with a scenic overlook, and connections to existing paths in Bettendorf, Iowa, and Moline, Illinois. The approximately $1-billion project includes twin river bridges, new interchanges, ramps, and local road reconfigurations.

According to Afifeh, the bridge will attract new businesses, jobs, and opportunities, along with making the Quad Cities a tourism destination. Quad Cities leaders are currently planning new developments such as rooftop restaurants, skate parks, and shopping centers near Memorial Bridge.
“This project is one of the largest investments ever by both Iowa and Illinois, and the local and regional enthusiasm for the project has been incredible,” Afifeh said. “The success of the project was accomplished through vision and perseverance, and the unprecedented collaboration of our states and communities. We are very proud of the extensive coordination, cooperation, and teamwork between the states, local municipalities and organizations, transportation and environmental agencies, bridge designers, construction management specialists, inspections staff, and the contractors to make the new bridge a reality.”
“We wanted to make sure that we were building a sustainable system well into the future. In doing so, we came up with the concept of a dual, divided system,” said Scott Schram, Iowa DOT District Engineer. “We explored that idea and found that it would help us contain that sustainable system that we were trying to achieve.”
The $1-billion project constructed four separate roadways, two in each direction, that divide through traffic on I-80 from local traffic on I-29. This unique freeway configuration created I-80 Express lanes and I-29/I-80 Local lanes, which reduced crashes, congestion, and operational challenges. The project also included color changeable message signs, pavement marking interstate shields, and static signing for better wayfinding. According to Schram, there has been increased interest in development in the Council Bluffs area since the beginning of construction.
“It [this project] really helps investments in the local community,” Schram said. “We’ve seen areas of development that have really taken off. We’ve got the Mid-America Center, which is the original draw for large events. There’s athletic facilities, hotels, restaurants, and shopping. These developments didn’t really start taking off until after these improvements were either underway or committed to financially by [Iowa] DOT.”
