The weekend and beyond

Travelers will encounter snow on Saturday, and it will be cold all weekend. Stay in touch with the Capital Weather Gang for the latest on that and check our winter driving tips. The forecast led to postponement of the Chain Bridge closing, but you will find that some other road and transit work might affect your plans for the weekend and the coming week.

Metrorail weekend delays
Red Line riders between Medical Center and Grosvenor should add at least 20 minutes to their travel time from 8 p.m. Friday through the midnight closing Sunday while Metro workers make tunnel repairs and replace rail fasteners that stabilize tracks. Every other train traveling toward Shady Grove will terminate at Friendship Heights and head back toward Glenmont.

Beltway detour in Tysons
If you're out late Friday night, watch for Beltway congestion in Tysons Corner. The exit ramp from the Beltway's outer loop to southbound Chain Bridge Road (Route 123) will close from midnight to 5 a.m. Saturday for work on the Dulles Metrorail project.

Meanwhile, drivers on eastbound I-66 will encounter lane closures near the Dulles Connector Road (Route 267) interchange Friday night and Saturday morning. See more details and a detour map in this posting.

Chain Bridge closing postponed
The forecast for the weekend led to postponement of the planned closing. It's probably going to be too cold for the concrete work and painting on the bridge deck that necessitated the plan for two weekend closings.

So here's the new schedule, weather permitting. Chain Bridge will be closed:
-- From 8 p.m. Feb. 5 to 5 a.m. Feb. 8.
-- From 8 p.m. Feb. 12 to 5 a.m. Feb. 15.

I-66 ramp fix postponed
Cold and wet weather this week forced the Virginia Department of Transportation to postpone its plan to reconfigure the ramps that lead from eastbound Interstate 66 to the inner loop of the Beltway.

The overnight work -- which should ease a major chokepoint for commuters -- is now scheduled for Tuesday night through Friday morning. See previous posting for details.

Overnight work on Anacostia Freeway
As part of the 11th Street Bridge Project, the District Department of Transportation is scheduled to do overnight work this coming week that will require closing one direction of the Anacostia Freeway (DC-295/I-295) at a time on successive nights next week.

On Wednesday, from midnight to 5 a.m., the entire southbound freeway between Pennsylvania Avenue and Howard Road will be closed for 40-minute intervals. The right lane will be closed at 7:30 p.m. Tuesday.

TuesdayThursday from midnight to 5 a.m., the entire northbound freeway between the 11th Street bridges and Pennsylvania Avenue will be closed to traffic for 40-minute intervals. In addition, the right lane will be closed starting at 7:30 p.m. Monday.

Alternative routes:
-- Northbound traffic can use the 11th Street or South Capitol Street bridges to access I-395 North, then go eastbound on New York Avenue to return to I-295.
-- Southbound traffic can take westbound New York Avenue to the Third Street Tunnel, to return to I-295 south of the closure.

Eastern Avenue bridge over Kenilworth Avenue
The District Department of Transportation is scheduled to close the old bridge over Kenilworth Avenue NE (DC-295) on Monday for complete reconstruction. Highway drivers notice the dings in the underside of the bridge where trucks have hit it. The new bridge will have higher clearances.

The bridge closing will last through mid-October. DDOT says it was able to decrease the length of the project from two years to less than a year by adopting construction methods that include pre-casting several large elements before delivering them to the site. See more details and a map in this posting.

Silver Spring traffic signal upgrade
Next week, Maryland's State Highway Administration plans to start a $1 million reconstruction of the traffic signals along Georgia Avenue in downtown Silver Spring.

The program, scheduled for completion in summer 2011, will upgrade signals between East West Highway and Wayne Avenue. In addition to rebuilding the signals and installing pedestrian countdowns, the work includes upgrading the sidewalk ramps and the nearby street lighting.

During the reconstruction, drivers will encounter daytime, single-lane closures on weekdays during off-peak hours. (Some of these intersections are major commuter routes, with lots of rush-hour congestion.) Daytime lane closures are also possible on weekends.

Dolley Madison ramp
Construction will close the exit ramp from the eastbound Dulles Connector Road onto Dolley Madison Boulevard overnight next week.

The ramp will be closed from 11 p.m. until 5 a.m. for five days beginning Monday. The closing is required to allow construction of one of the many piers that will support the elevated tracks. Drivers will be directed to use the exit ramp to southbound Route 123, and to use the traffic signal to access the northbound lanes.
