Innovation Implementation: FHWA Announces New Every Day Counts Innovations

Eleven game-changing technologies and practices are on the round-three roster of Every Day Counts, the Federal Highway Administration initiative to accelerate mainstream use of innovations that can benefit the nation’s transportation system.

Over the next two years, FHWA will work with transportation agencies and their partners to deploy the EDC-3 innovations. They range from efficient electronic tools and easy-to-build bridges to time-saving planning techniques and congestion-cutting work zones.

"These are market-ready innovations that can help the transportation community shorten project delivery, enhance roadway safety and improve environmental sustainability," said FHWA Acting Administrator Gregory Nadeau. "The EDC-3 innovations align with our focus on efficiency—saving time, money and lives—through technology and collaboration."

Six of the innovations focus on shortening project delivery, while five enhance mobility, safety, quality and environmental sustainability. Details on the complete EDC-3 innovation roster is on the Every Day Counts website.

Arizona Holds ABC Innovation Exchange

The Arizona Council for Transportation Innovation hosted the third in its Innovation Exchange Campaign series on new technologies and processes. About 75 transportation professionals participated in the August 19 event, at which industry representatives gave presentations on accelerated bridge construction techniques and alternatives to traditionally build bridges and box culverts. The next innovation exchange is scheduled for September.

Colorado Opens Innovative Intersection

An August 15 ribbon-cutting marked the completion of the Colorado Department of Transportation’s first continuous-flow intersection, also known as a displaced left-turn intersection, at the U.S. 160/U.S. 550 west intersection in Durango. The busy intersection, which serves as the gateway to Mesa Verde National Park, experienced lengthy backups and delays in the past. The CFI reduces congestion and increases safety at high-traffic intersections. Other innovations on the $6.7 million project included a high-intensity activated crosswalk, or HAWK, pedestrian signal and raised curbed medians and islands for pedestrians.

Michigan Showcases Slide-In Bridge Technology

A Michigan Department of Transportation and FHWA showcase offered participants the opportunity to watch slide-in bridge technology in progress at two project sites on U.S. 131 and M-50 in Grand Rapids. Representatives of state transportation departments, universities, local infrastructure agencies, contractors and consulting firms attended the August 14 event. Project principals discussed the real-time opportunities generated by the use of slide-in construction. "The bridge slide showcase was a good opportunity to gain more information that will help us use this technique in the future," said Adam Price, transportation project specialist with the Tennessee Department of Transportation.

Missouri Demonstrates 3-D Stringless Paving

The Missouri Department of Transportation hosted a workshop and field demonstration on three-dimensional engineered models for stringless paving. The August 13 and 14 event in St. Louis showcased the benefits of 3-D stringless technology in constructing portland cement concrete pavements for more than 75 construction professionals. It featured a demonstration of stringless paving with construction of interchange ramps at Route 364 and Page Avenue in St. Louis.

Montana Replaces Bridges on Weekends

Accelerated bridge construction techniques and three weekend road closures were used to replace three bridges on U.S. 12 east of Townsend, Montana. The final weekend closure was August 2. Techniques used for the replacements included completing the drilled shaft foundation before the 6 p.m. Friday closure and using prefabricated bridge caps and beams. The contractor completed the first replacement by 5 a.m. Monday, the second replacement by 5 p.m. Sunday and the third by 1 p.m. Sunday, earning a $54,400 incentive for finishing the bridge replacements ahead of schedule.

Nevada to Use Design-Build on Project NEON

The Nevada Department of Transportation Board of Directors has switched from a public-private partnership to the design-build method to deliver the biggest project in Nevada history. The board made the decision August 18 after reviewing the alternatives with input from Nevada DOT and FHWA staff and consultants. Project NEON would widen I-15 in downtown Las Vegas, reconstruct two interchanges and expand the high-occupancy vehicle network. The P3 process added four bridge replacements, expanded the HOV limits and introduced active traffic management to the I-15 corridor. Those items will be added to the D-B contract.

Rhode Island Moves Bridges With SPMTs

The Rhode Island Department of Transportation is using accelerated bridge construction on its project to rehabilitate the I-95 Barton Corner Bridge project in Warwick. The two halves of the bridge were built on land next to the overpass. In one phase of the project, self-propelled modular transporters were used to remove and replace the existing northbound bridge overnight. In two weeks, the old southbound bridge will be removed and the new bridge will be moved into place using SPMTs. It’s the first time the Rhode Island DOT has used SPMTs.
