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

  • On the BW Parkway, road work makes way for rail work

    Midday delays and work zones have become the new normal on the Baltimore-Washington Parkway near the Hyattsville exit. The construction will make way for Purple Line trains several years for now.
    The light rail line will run under the Baltimore-Washington Parkway on Route 410 between Riverdale Park and the proposed Beacon Heights-East Pine Station. The existing underpass is not wide enough to send four lanes of traffic and a rail line underneath the parkway. The solution: reconstruction of the bridges. 
    In late March, a temporary bridge span was pushed into place above Route 410. Last weekend, northbound traffic on the BW Parkway was shifted onto the new bridge and onto new pavement on both sides of it.
    This weekend, a temporary bridge for southbound traffic will be launched, according to Purple Line Transit Partners. Route 410 is scheduled to be closed late Saturday night into early Sunday morning. The road is expected to reopen by 5 a.m.
    Purple Line Transit Partners plans to shift southbound traffic onto the other temporary span during the final weekend of June.
    The closure of the existing bridges will allow crews to expand the width of the underpass. Once the modifications to the overpasses and abutments are finished, the temporary bridges will be deconstructed.
    Daytime lane closures are likely to continue near the worksite for some time.
    The effort to send light rail down a more than 16 mile long path between Bethesda and New Carrollton is involved and multi-faceted. The project has run into cost overruns and delays. The construction phase of the project is projected to last through 2022.
