This project consisted of the construction of new overhead gantries, associated roadway reconstruction and resurfacing, and the demolition of the existing toll plazas so that Open Road Tolling (ORT) equipment could be installed on the overhead gantries. This equipment will enable the Authority to collect toll transaction data from transponders and video imaging so that conventional toll plazas are no longer needed on the expressway system. After the new toll collection equipment was in operation, we were then able to demolished the existing toll plazas and complete the associated roadway realignment and reconstruction and resurfacing.
This project required close coordination between DNCC and the installer of the ORT equipment, Trans Core, who was working in the same areas and at the same times as us. Time was of the essence and construction staging was critical to maintain the overall schedule of the project. Shop drawings were reviewed and returned within two weeks by the Engineer of Record (EOR) upon contractor submittal. A new conduit and communication system including the installation of emergency generators, fuel tanks, service points, transfer switches, fiber optic cable and splicing, etc. was constructed by DNCC so that power and communication were available for the ORT equipment at the time of TransCore’s installation. There were a total of twelve gantries fabricated and erected. Our scope of work also included 15,000 Lf of temporary concrete barrier wall, 43,000 SY of new base work and asphalt, and storm drainage work.
