Construction in DC and Montgomery County
Even as we head toward winter, there are developments on a couple of road construction projects. Here's what many commuters will see for the first time today:
Northbound traffic has been shifted to the newly constructed temporary road at Montrose Parkway/Randolph Road. On Thursday, the southbound traffic also will be shifted to the detour road.
Until the traffic switch is complete this week, drivers on East Jefferson Street will be detoured to Executive Boulevard and onto northbound Rockville Pike. The temporary road, which has the same number of lanes as the pike, was created to allow construction of a new interchange.
DC Bridge Project
The District Department of Transportation is scheduled to start an extensive rehabilitation project on the 9th Street and 10th Street SW Bridges over I-395.
The project, scheduled to last a year, requires closing the 9th Street Bridge. The 10th Street Bridge and the two ramp bridges from the 9th Street tunnel to I-395 will remain open during most of the construction, but some temporary closures may be necessary, DDOT says. Sometimes, the lane configurations in the 9th Street tunnel will be changed.
Among other things, the concrete bridge deck on the 9th Street Bridge will be replaced, and a new walkway and staircase will be built to Frontage Road at L'Enfant Plaza. The 10th Street Bridge's beams will be repaired. Drivers also will see new roadway lighting and a new surface on the bridges. DDOT says it also will repair the roof slab of a Water and Sewer Authority pumping station under 9th Street.
