Tulsa Zoo Train Tunnel

Owner: City of Tulsa

System: Wet Shotcrete with Air-O-Form System

Completed: 1993


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.
