Thanks to a couple of readers for passing on the First Street Tunnel Community Update from DC Water:
“DC Water is diligently working towards making the First Street Tunnel operational by late September 2016. Construction is behind schedule due to the excavation of the frozen ground taking longer than anticipated and delays in the delivery of some key custom fabricated equipment. Major remaining work includes the testing of the system, demolition of temporary works and street restoration. We apologize for the delay and appreciate your patience as we move to project completion.
