Telegraph Road/Beltway ramp

The ramp from the Capital Beltway’s inner loop (Interstate-95/495 South) to southbound Telegraph Road is scheduled to close from 9 a.m. to noon Friday. Workers who are part of the Woodrow Wilson Bridge project are rebuilding the interchange.

The ramp closing is likely to have a significant impact on local traffic, and drivers should find alternative routes if possible Friday morning. Motorists are advised to seek alternate routes to avoid delays.

For motorists who can’t avoid the area, these detours for southbound Telegraph Road will be in place:

Drivers on the inner loop’s THROUGH lanes will continue on the inner loop to the exit for South Van Dorn Street, then return on the outer loop to the exit for southbound Telegraph Road.

Drivers on the inner loop’s LOCAL lanes will take the exit for Pershing Avenue, then go right on Stovall Street, right on Eisenhower Avenue and right on Mill Road to southbound Telegraph Road.

The ramp is scheduled to close again on Wednesday and Thursday between 9:30 a.m. and 1:30 p.m.

Metro weekend delays

The maintenance delays this weekend are on all lines but the Green Line.

Red Line: From 9:30 p.m. Friday through the rail system’s midnight closing Sunday, trains will share a track between Grosvenor and Twinbrook. Crews continue to work on platform rehabilitation projects at the White Flint and Twinbrook stations.

From 10 p.m. Friday through the Sunday closing, trains will share a track between Takoma and Forest Glen. Workers are upgrading the train control rooms.

Through the weekend, trains will leave the ends of the line at Shady Grove and Glenmont about every 24 minutes. Between 9 a.m. and 9 p.m. Saturday and Sunday, service will be more frequent in the middle of the line. Trains should arrive at the platforms between Grosvenor and Takoma about every 12 minutes.

Orange/Blue lines: From 10 p.m. Friday through the Sunday closing, trains will share a track between Eastern Market and Stadium-Armory . Workers will be replacing rail fasteners.

All trains will leave the ends of the lines about every 20 minutes.

Yellow Line: From 10 p.m. Friday through Sunday’s closing, trains will share a track between Pentagon City and L’Enfant Plaza. Workers will be replacing rail fasteners and installing communications cable, which will eventually improve cellphone service in the underground stations and the tunnels.

The line will operate trains about every 20 minutes between Huntington and Mount Vernon Square.

Humpback Bridge paving

On Saturday, the George Washington Parkway ramps to and from Interstate 395 near the Humpback Bridge are scheduled to be paved. Crews will work first on from southbound I- 395 to the northbound parkway. Then they will move on to the ramp from the southbound parkway to southbound I- 395.

It will take about four hours to do each ramp, and during that time, the ramp will be shut completely.

Bay Bridge travel

A summertime reminder about the hours when drivers are likely to encounter the least congestion on the Chesapeake Bay Bridge to the Eastern Shore:

Thursday before 2 p.m., Friday before 10 a.m. and after 10 p.m., Saturday before 7 a.m. and after 5 p.m., Sunday before 11 a.m. and after 10 p.m.

Fairfax Parkway interchange

Drivers using the eastern side of the Fairfax County Parkway will have to wait a little longer to get the full benefit of the new interchange at Boudinot Drive near Interstate 95.

The Virginia Department of Transportation partially opened it up this week, so that cars from Boudinot Drive and from Fullerton Road in Newington could reach the parkway’s northbound lanes.

But the ramp from the southbound parkway to Boudinot Drive and I-95 will not open for several more weeks. Project managers discovered that they need to stabilize a retaining wall before opening that section of the new ramp, VDOT spokesman Mike Salmon said.

This interchange is known as Phase IV of the Fairfax County Parkway project and is being built with money from the federal stimulus program.

Fairfax street closing

Poplar Tree Road between Braddock Ridge Drive and Sully Park Drive in Centreville will remain closed to traffic for a little over two months, the Fairfax County Department of Transportation says.

Work is beginning on a project that will widen that portion of Poplar Tree Road to a four-lane divided roadway. While construction will take about a year, the county plans to reopen the road to traffic by Sept. 2.

Anacostia Drive closing

To accommodate work on the District’s 11th Street Bridge, the National Park Service plans to close Anacostia Drive SE between Good Hope Road and Nicholson Street from 8 p.m. to 6 a.m. each night Sunday through Friday.

Intercounty Connector signs

On Tuesday night, the Maryland State Highway Administration plans to start lane and ramp closings on southbound Interstate 95 at the Powder Mill Road interchange (exit 29). Workers will be installing overhead sign structures for a future section of the Intercounty Connector.

Tuesday through Thursday nights, the right lane on southbound I-95 will be closed before exit 29 beginning at 7 o’clock. The two right lanes will be closed beginning at 11 p.m., and the ramp from southbound I-95 to eastbound Powder Mill Road will be closed between 11 p.m. and 5 a.m.

Drivers heading for eastbound Powder Mill from southbound I-95 will be detoured by continuing on southbound I-95 to the park and ride lot at the Capital Beltway interchange, then onto northbound I-95 up to Powder Mill Road.

The highway administration recommends drivers on southbound I-95 consider alternative routes, including the Baltimore-Washington Parkway or Route 29 (Columbia Pike) to avoid delays.
