Maintenance Challenge for Road Delineators on Express Lanes and Highways

Ennomotive, the leading open innovation platform for engineering challenges, just launched a competition to find an efficient solution to improve the cleaning and replacement process of road delineators in highways.

 Cintra, with Ferrovial Agroman as the main constructor, has improved Interstate 77 in northern Charlotte, North Carolina, by adding electronic-tolled express lanes along 26 miles of the highway. Once construction is finished, I-77 Mobility Partners (I-77 MP), a consortium led by Cintra, will be responsible for the operation and maintenance of the project.

I-77 Express runs adjacent to the existing general-purpose free lanes, separated by plastic delineators, whose main purpose is to prevent toll violators from entering or exiting the toll lane without crossing a toll gantry.

As established in the Concession Agreement, delineators must be cleaned to meet the reflectivity requirements and be replaced when damaged or missing. Consequently, Cintra is looking for solutions to reduce the maintenance cost of the delineators while complying with the contract requirements.

This online competition is open worldwide to any professional, company, or tech center from different industries and technical backgrounds that wants to propose a solution for this challenge.

Ennomotive offers a 15,000 € prizes to be shared among the best ideas for this competition. Interested participants should sign up at and submit their solution before April 6.
