[4] The tunnel consists of a single bore, 895 meters (2,909 feet) in length, with a six-percent roadway grade outward from the center towards each exit.
Forced transverse ventilation is potentially provided by three automatic high-speed Westinghouse Sturtevant blower fans located in a tower at the north entrance.
Pumps located under the road surface counter accumulation of water by draining it back into the ship channel.

Nevertheless, HCTRA's involvement will include plans to improve the operations of both facilities, as well as much-needed repairs and upgrades.
