The week ahead for traffic, transit

There's lots of road and rail work scheduled for this short work week across the D.C. region. We're in that period when the road work is intense and tourists are in town, but Washingtonians haven't fled for vacations in great numbers, so patience is necessary. The Capital Weather Gang says temperatures generally will be hot, and there are chances of afternoon thunderstorms on Tuesday, Thursday and Friday.

Route 7 lane shift
The Dulles Metrorail project is preparing to shift the lanes of eastbound Leesburg Pike (Route 7) between Best Buy and Chain Bridge Road (Route 123) in Tysons Corner so a new station can be built in the median. The lane shifts are scheduled to begin overnight Friday. If bad weather interferes, the transition will be postponed until the following Friday night.

The lane shift, which will move the three traffic lanes about 40 feet to the right, will remain for the next three years, until the rail project's completion.

New York Avenue
The traffic pattern at New York and Florida avenues NE is scheduled to change late this week, as the District's New York Avenue reconstruction project moves into a new phase.

After the changes, traffic will flow in a circular pattern around the Wendy's restaurant at the intersection. Drivers, cyclists and pedestrians all will need to look sharp, as this will be a very different experience for them in a heavily traveled area. The change is scheduled for 9 p.m. Friday.

New Beltway bridge
The Capital Beltway's outer loop is scheduled to shift onto a new bridge over Route 123 in Tysons Corner this week, as the HOT lanes project advances another step. The Beltway traffic shift, set for Wednesday night, weather permitting, will be followed eight days later by a full weekend closing of Route 123 to demolish the old outer loop bridge.

The shift of traffic on the outer loop in Tysons Corner is scheduled to begin at 9:30 p.m. Wednesday and be done by 5 a.m. Thursday. Drivers will shift to the right as they approach the Route.123 interchange on I-495 south. Exit ramps to Route 123 north and south have been realigned. As motorists pass the Route 123 interchange, they will shift back to the current lane configuration.

Ohio Drive
The National Park Service plans to start the next phase of road reconstruction this week on Ohio Drive between the Lincoln Memorial and the Kennedy Center. This will mean changes in rush-hour and off-peak traffic patterns.

Two lanes will always be open inbound during the morning rush and two lanes outbound during the evening rush. Pedestrians and cyclists are being detoured around the east side of the Lincoln Memorial during the entire program. All the work should be done by late fall.

11th Street Bridge
On Wednesday night, watch for scheduled restriping of the pavement on and around the inbound 11th Street Bridge Project. There will be lane closures on the inbound bridge and on the ramps starting at the Anacostia Freeway.

From 8 p.m. to 5 a.m.:
-- The on-ramp from northbound I-295 to the inbound bridge toward I-395 will be reduced to one lane.
-- The on-ramp from 13th Street to the inbound bridge toward I-395 will be reduced to one lane.

From 10 p.m. to 5 a.m.:
-- The off-ramp from the inbound bridge to 12th Street/M Street Exit will be closed, with a signed detour in place.
-- The inbound bridge will be reduced to one lane.

Chain Bridge
Chain Bridge got its third lane back last week after a nearly year long rehabilitation project on the aging bridge structure. The traditional rush-hour traffic pattern has been restored. In the morning, there are two lanes for District-bound traffic. In the evening, there are two lanes for Virginia-bound traffic.

Dulles Metrorail/Magarity Road
Drivers who use Magarity Road in the McLean-Falls Church-Tysons area may encounter significant delays on some nights this week when the road closes between Olney Road and Great Falls Street between 9 p.m. and 6 a.m.

The Dulles Metrorail project is installing decking on a new bridge that will carry tracks for the new line in the median of the Dulles Connector Road across Magarity Road.

Drivers could detour by using Anderson Road, Chain Bridge Road and Great Falls Street.

Beltway/Forestville Road
The Maryland State Highway Administration is beginning the rehabilitation of a Prince George's County bridge over the Beltway. The northbound lane of Forestville Road will close between Allentown Road and the exit ramp from the Beltway's inner loop. Only southbound motorists will be able to use Forestville Road across the Beltway.

Crews might also close a single lane of the Beltway from 9 a.m. to 3 p.m. Mondays through Fridays, and from 9 p.m. to 5 a.m. Sunday through Thursday nights. Work should be done by fall 2011.

Metro weekend work
There will be no Orange Line service between the East Falls Church and West Falls Church stations again during the next two weekends. The Dulles Metrorail project will be working on the first of a series of construction programs that by 2013 will connect the new rail line to the rest of the system.

Metro will operate free shuttle buses between the two stations, but riders should add at least half an hour to their travel times.

The service disruptions will begin on each of the Friday nights. From 10 p.m. to the 3 a.m. closing this Friday and June 11, trains will share a track between East Falls Church and Vienna. Riders traveling between the stations at those late-night hours should add at least 40 minutes to regular travel times.
