Travelers can look forward to a beautiful weekend, the Capital Weather Gang says. Major road delays during the daytime are unlikely in the D.C. area. Metro, however, plans track work on four lines, including a shutdown of Orange Line train service between East Falls Church and West Falls Church.

After the weekend, high heat will make a strong comeback. Look for unusual traffic congestion Thursday through next Sunday in the Manassas area during the 150th anniversary observances for the Civil War battle.

Here are some tips to guide your travels through the weekend and next week.

Brunswick Line

MARC Train 881, normally a 6 p.m. departure from Union Station on the Brunswick Line, is canceled for Friday night because of CSX track work. Train 879, normally scheduled to leave at 5:40 p.m., will wait at Union Station an extra 20 minutes, leaving at 6 p.m. and making all stops. The track work is scheduled to continue for several weeks, but tonight’s train is the only one canceled.

Metro weekend delays

Orange Line: From 10 p.m. Friday through the train system’s midnight closing on Sunday, trains will not operate between East Falls Church and West Falls Church. Instead, Metro will provide free shuttle buses.

The two stations will remain open. The last train will leave the end of the line at Vienna at 2:05 a.m. Friday and Saturday nights and at 11:05 p.m. on Sunday. That’s 20 minutes earlier than usual.

Between Vienna and West Falls Church stations, trains will operate every 24 minutes, sharing one track while workers replace cross ties and insulators.

Traveling through the work zone will add about 30 minutes to a rider’s normal travel time.

Red Line: From 10 p.m. Friday through Sunday’s closing, trains will share a track through downtown D.C., between Dupont Circle and Judiciary Square. Workers will be doing some ceiling repairs at Farragut North, which really needs it, and replacing rail fasteners, and installing new emergency phones and communication cables.

Between 9:30 a.m. and 9 p.m. Saturday and Sunday, trains will leave the ends of the line at Shady Grove and Glenmont every 10 minutes. Every other train from Shady Grove station will end its run at Dupont Circle and turn back. Every other train from Glenmont station will terminate at Union Station.

At all other times this weekend, the trains will leave every 20 minutes from Shady Grove and Glenmont, but will encounter delays in the single-tracking zone, which could be a half hour.

The last train from Glenmont will leave at 2:26 a.m. Friday and Saturday nights and at 11:26 p.m. on Sunday. That’s 11 minutes earlier than usual.

Blue/Yellow lines: From 10 p.m. Friday through Sunday’s closing, trains will share a track between Braddock Road and Van Dorn Street and Huntington stations. Workers will be installing new rail and other equipment.

Blue Line trains will leave the ends of the line at Franconia-Springfield and Largo Town Center about every 24 minutes.

Yellow Line trains will operate between Huntington and Mount Vernon Square about every 24 minutes. They won’t go north to Fort Totten as they normally would on weekends.

Riders should add about 20 minutes to their normal travel time through the work zone.

Dulles Metrorail/Tysons Corner

Drivers in Tysons Corner can expect overnight closings of part of the intersection of Route 7 (Leesburg Pike) and Westpark Drive/Gosnell Road beginning Sunday and continuing for up to six weeks.

Cranes will be used to start building elevated spans to carry the Dulles Metrorail tracks over the intersection, near the Westpark Hotel, the Ernst and Young building and the former Business Bank building.

Through traffic can continue on Route 7, but traffic on Westpark/Gosnell will be detoured onto Route 7 following this path:

Southbound Westpark Drive traffic can turn right on westbound Route 7, then make a U-turn at Spring Hill Road and turn right on Gosnell Road. Northbound Gosnell Road traffic can turn right on eastbound Route 7, pass under Route 123, turn left on International Drive, left on Chain Bridge Road (Route 123), then take the exit ramp to Route 7 and turn right on Westpark Drive.

The closings are scheduled for 11 p.m. to 5 a.m. Sundays through Fridays for the next four to six weeks. The work is taking place near where a large yellow and blue crane has been assembled in the median of Route 7. The crane had been used to build rail bridges along the northwest side of Route 123 before it was moved several weeks ago.

Beltway/Kenilworth Avenue

Drivers will find up to three lanes on the Capital Beltway’s inner loop (I-95/I-495 South) from Sunday through Thursday nights at the Kenilworth Avenue bridge, which is undergoing a rehabilitation scheduled to be done by fall.

The phased-in lane closings will start with a single right lane closing at 8 p.m. and progress to a three-lane closure by 10 p.m. One lane will remain open to traffic.

The overnight lane closures will last several weeks while the concrete deck is removed. All lanes will reopen by 5 o’clock each morning.

Croom Station Road

The Prince George’s County Department of Public Works and Transportation plans to close the 7700 to 8100 blocks of Croom Station Road to through traffic from 7 a.m. to 5 p.m. starting Monday.

During those hours, workers will replace a storm drain pipe. This portion of the road is in a swampy area with no shoulder, so the staging area for the emergency repair must be placed in the roadway, the department said.

People who live in the 7700 block can reach their homes via Route 301. Those in the 8000 block will have access from Croom Road. Drivers who normally use Croom Station Road as a through street should stick with Route 301 during the work, which is scheduled to be done around July 25.

Beltway/Telegraph Road

Starting next Friday, the Woodrow Wilson Bridge project plans to close westbound Pershing Avenue in the Eisenhower Valley section of Alexandria. Drivers won’t be able to take Pershing Avenue to Telegraph Road North toward Duke Street.

The closing will last about two months, while workers build the new Pershing Avenue approach to Telegraph Road to align with the widened Telegraph Road bridge over the railroad tracks.

Northbound drivers will detour by taking Stovall Street to a left on Eisenhower Avenue to the traffic circle to Holland Lane to Duke Street. There will be detour signs posted.

Beltway/Silver Spring

Beginning this coming week, drivers on the Maryland side of the Capital Beltway will have another project to contend with: The State Highway Administration plans to resurface more than four miles on both the inner and outer loops between Colesville and Seminary roads. The work should be done before Thanksgiving.

Just east of the new project, workers are rehabilitating the Beltway bridge over the Northwest Branch in Silver Spring, and motorists also are experiencing congestion because of lane shifts in that area.

The new resurfacing project will include the ramps at the Georgia Avenue and Colesville Road interchanges.

Here are some details about the upcoming lane closings:

On both loops, single lane closings will occur Monday through Friday between 9 a.m. and 3 p.m. and overnight Sunday through Thursday between 8 p.m. and 10 p.m. Double lane closings can occur overnight Monday through Friday between 10 p.m. and 5 a.m.

New Hampshire Avenue

The Maryland State Highway Administration also has launched a project to widen New Hampshire at Adelphi Road, just south of the Capital Beltway in Silver Spring, and create an additional through lane at the intersection.

Watch for single lane closings on New Hampshire between 9 a.m. and 3 p.m. weekdays. There may be additional lane closures overnight, especially as the work nears completion in spring 2012.
