UCAR Boulder Tunnel
UCAR (University Corporation for Atmospheric Research) manages NCAR (National Center for Atmospheric Research) on behalf of the National Science Foundation.
SUMMIT has been engaged to strengthen the tunnel using state-of-the-art carbon fiber reinforcement. After installing the carbon fiber, we added additional concrete to the top of the tunnel to provide a proper slope. We then added more carbon fiber along with a new waterproofing system. This will allow heavy machinery to travel over the top of the tunnel for years to come.
