The $10.4 million contract was awarded to a joint venture that includes A. Servidone Inc. and B. Anthony Construction Corp. of Old Bridge, New Jersey who will construct an embankment, retaining walls, storm water basins and substructures for relocation of the toll plaza at Interchange 8 in East Windsor, Mercer County.

The project marks the first construction work related to the $2.5 billion widening of the Turnpike between interchanges 6 and 9 and will result in the roadway through the area having six northbound lanes and six southbound lanes.

At press time, the construction is set to begin in June with an expected project completion date scheduled for 2014.
