Cone Zone: Updates on D.C.-area work zones

  • Lane reductions for storm water diversion

    Aga writes us about a work zone on her daily commute that "often blocks two lanes" near the Bladensburg Road and Mount Olivet Road intersection, adding that it "has been going on for few months now and it does not seem to end."
    Never-ending work is a common lament, on and off the highways. In the case of this project, the ultimate completion date remains on the distant horizon but the most impact lane closures in the near term could be mostly in Aga's rear-view mirror. 
    Most of the lane reductions that drivers have encountered this year on Mount Olivet Road, Bladensburg Road and Rhode Island Avenue are just a small, visible component of a massive underground project that we've detailed in this blog in recent months — DC Water's Northeast Boundary Tunnel project. 
    Construction of the miles-long storm water tunnel from near Robert F. Kennedy Stadium to Bloomingdale is well underway. By 2023, DC Water looks forward to a 98 percent reduction in sewage overflow into the Anacostia and Potomac rivers when the entirety of the tunnel system is put into service. 
    The work zone on Mount Olivet Road is for the construction of dewatering wells that actually lower the water table to prepare for the underground arrival of the tunnel boring machine, according to the utility company. 
    Traffic has been shifted slightly south near the work site for a few months. 
    The active lane closures within the 250-foot work zone are scheduled to take place Monday through Friday from 7 a.m. to 7 p.m. Drivers are asked not to tail-gate and to drive distraction-free to keep the workers safe.
