Additionally, ten miles of existing conduit was proofed for fiber optic cable installation, including man hole rehabilitation. Over 120,000 feet of fiber optic trunk line cable, as well as drop cables and power service, was installed to 59 cabinets, which all included battery backup systems. World Fiber installed 52 new structures for tolling equipment and overhead signage, and horizontal extension arms were attached to the 35 gantry structures for tolling equipment installation. Vertical extension arms were installed on structures for CCTV installations. Ten variable message signs were installed for tolling rate displays. A 5.8 GHz wireless radio system was installed for system redundancy. The Ethernet communications network included multiple VLANs, including Layer 2 and 3 switch installations.
