Tulsa Zoo Train Tunnel
Owner: City of Tulsa
System: Wet Shotcrete with Air-O-Form System
CSC does not typically get opportunities to get involved in new construction. In this case the Tulsa Zoo wanted to create a tunnel for their train to go through. We used an Air-O-Form system (basically a balloon that stayed inflated through the course of the job) and reinforcing steel was set. A wet shotcrete process was used to apply concrete to create the tunnel that is still in place today.
