Cintra, with Ferrovial Agromán as the main constructor, has improved Interstate 77 in northern Charlotte, North Carolina, by adding electronic-tolled Managed 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.
The I-77 Express Lanes run adjacent to the existing general-purpose free lanes, separated by plastic delineators (see https://www.ferrovial.com/en/business/projects/i-77-express-lanes/). Delineators’ main purpose is to prevent toll violators to enter or exit the toll lane without crossing a toll gantry.
The Concession Agreement (CA) requirements establish the replacement of all damaged or missing delineation posts/reflectors. They shall be free of functional defects and visible to the traveling public. Current delineators, as part of the routine maintenance, will have to be cleaned to accomplish the reflectivity requirements in the CA.
Sprayed cleaning solutions have been tested, but the dirt does not come out as it depends on the type of dirt they present (e.g. oil-related dirt, very difficult to eliminate). Maintenance must be performed with rolling closures from 9 pm to 6 am.
