Following a nearly year-long construction effort, DC Water has completed repairs on a nine foot diameter, 140-year old sewer tunnel on 22nd Street Northwest. Construction was done in two phases, with the second phase completed one month ahead of schedule and under budget.
The work zone in the area of 22nd and Q streets is being demobilized. All northbound lanes are now open, and southbound lanes will be reopened later today prior to the evening rush hour.
The tunnel section is part of the Northwest Boundary Trunk Sewer, built in the 1800’s. Last year, an inspection revealed a large void in the soil above measuring 13 feet long and 10 feet wide and the tunnel in danger of collapse, necessitating the long-term closure of a section of 22nd Street.
Ahead of schedule and under budget in Washington D.C.? I'm impressed. Put those guys in charge of the city. It is a sewer, after all.
The Wombat has Rule 5 Sunday: Overall Beauty up more or less on time and under budget.
Thanks Fritz, but no way I can afford the maintenance.
