Irvine-based toll road operator Cofiroute USA got a $2.8 million contract to work on toll collectors on four bridges that cross the Delaware River, connecting Pennsylvania and Southern New Jersey.

The three-year contract was awarded by the Delaware River Port Authority, a Camden, N.J.-based agency that owns and operates the bridges. The bridges carried about 96 million vehicles last year.

Cofiroute is expected to provide training and management services, and will work alongside LAZ Parking, a Hartford, Conn.-based company that manages about 1,650 parking lots in the U.S. LAZ will manage hiring, training and accounting for the toll collectors.

Cofiroute and LAZ are subsidiaries of Paris-based Vinci Group, which focuses on construction and management of public infrastructure and amenities globally. Vinci had about $50 billion in revenues last year. It employs about 192,000 workers in roughly 100 countries.

Cofiroute has 100 employees overall, including 65 in Orange County. It serves as the operator of the 91 Express Lanes owned by the Orange County Transportation Authority, a 10-mile stretch on the Riverside Freeway that runs from the Costa Mesa (55) Freeway to the Riverside County border. Cofiroute recently got a five-year contract valued at $60 million to provide management services for the Express Lanes once an expansion is completed in 2017.
