The $73 million deal involves building a new back office system for Orange County Transportation Authority and Riverside County Transportation Commission near Los Angeles.
Vinci Highways will provide and operate the system and a customer service centre for the 91 Express Lanes, a 29km link connecting Anaheim and Corona. The firm won the deal through its subsidiary Cofiroute USA.
TollPlus, a company in which Vinci acquired a strategic stake in 2016, will provide a modern back office system with new features.
The firm says that this will allow transaction management and improve financial performance. It will be able to handle more than 150,000 accounts and 37 million trips per year.
