Southeastern Virginia is comprised of seven cities, each of which is waterfront, and many of which are separated by large bodies of water.  The Hampton Roads Bridge Tunnel was constructed in the mid 1950's to connect Norfolk and Virginia Beach with Newport News and Hampton without obstructing marine traffic.  The Virginia Department of Transportation launched one of the largest infrastructure projects in North America to expand the Hampton Roads Bridge Tunnel.  Chief Engineer Ryan Banas joins Infrastructure Junkies to explain this incredible feat of infrastructure expansion, and in the process, tells our audience exactly how this bridge goes under water.
