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:

Rockville Pike
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.

I'm not sure where the description of the detours related to the Rockville Pike project came from, but they don't make sense to me...

East Jefferson St. and Executive Blvd. are actually the same road (name change at Montrose Rd.) and they are parallel to Rockville Pike, so how/where is there a detour from one to the other?

I'm trying to figure that out, too.

By my understanding of the following page, it sounds like they will be closing Montrose between Jefferson/Exec and 355. So if you are traveling S on Jefferson to get to 355 at Montrose, they are going to make you keep going on Exec to Old G-town. I could be wrong, who knows.

On a side note: Executive, E Jefferson, Rollins, Twinbrook, Nebel and Parklawn are going to get more congested. Great.
