Travelers in the D.C. region are in for a typical July weekend, the Capital Weather Gang says: hazy, hot and humid, with some storms wandering around.

Those conditions are just right for summer getaways, but those sticking around, Cirque du Soleil is at Verizon Center for the weekend, the Hip-Hop Theater Festival continues through Saturday, which is also the date for the Lake Arbor Jazz Festival and the Bastille Day party at Bistrot du Coin in Dupont Circle.

See our Going Out Guide for a complete roundup of weekend entertainment.

Getting there is usually less entertaining, but ignorance is not bliss when it comes to road and transit delays, so here’s my roundup of the obstacles that could lie in your path.

Beltway paving

Drivers on the Capital Beltway in the Alexandria area will encounter weekend lane closings for paving in the LOCAL section of the inner loop, the Wilson Bridge project says, but project managers hope to have the LOCAL lanes completely open by 5 a.m. Monday.

The goal had been to get this done by last weekend, but the recent bad weather slowed progress. So until Monday morning, the inner loop’s LOCAL section will continue to be a single lane between the Telegraph Road interchange and the Cameron Run bridge. Both of the inner loop’s THRU lanes are open.

Meanwhile, work continues on the outer loop lanes between the Springfield interchange and the bridge.The outer loop’s LOCAL segment will remain a single lane through this month while paving is underway. The THRU lanes are open.

Metro weekend delays

The disruptions for Metro’s rail maintenance program will affect all lines from 10 p.m. Friday though the rail system’s midnight closing Sunday.

Orange Line: Trains will share a track between East Falls Church and West Falls Church. Expect minor delays, Metro says.

Blue Line: Free shuttle buses will replace trains between Braddock Road and Pentagon City. The stations at Reagan National Airport and Crystal City will be closed.

Trains will operate between Franconia-Springfield and Braddock Road and between Pentagon City and Largo Town Center at their regular weekend times. Riders using the buses through the work zone should add about half an hour to normal travel times, Metro says.

Yellow Line: As with the Blue Line, buses replace trains between Braddock Road and Pentagon City. Yellow Line trains will operate between Huntington and Braddock Road and between Pentagon City and Mount Vernon Square at regular weekend intervals, Metro says.

Red Line: Trains will share a track between Takoma and Forest Glen. They will leave the ends of the line about every 20 minutes. Add 15 minutes to get through the work zone.

Between 9:30 a.m. and 6 p.m. Saturday and Sunday, more trains will operate between Shady Grove and NoMa-Gallaudet, so trains in that zone should arrive at platforms about every 10 minutes.

Green Line: Trains will share a track between Fort Totten and Prince George’s Plaza. They are scheduled to operate every 16 minutes, but add about 10 minutes to get through the work zone.

New York Avenue Bridge

New York Avenue NE between Penn Street and Florida Avenue will be closed from 10 p.m. Friday through 1 p.m. Saturday for work on the long-term reconstruction of the bridge over the railroad and Metro tracks.

Westbound traffic will be redirected at Penn Street to Sixth Street and Florida Avenue and then back onto New York Avenue. Eastbound traffic will be redirected at Florida Avenue to Sixth Street and Penn Street and then back to New York Avenue.

Rhode Island Avenue or H Street NE are potential alternatives for drivers who want to avoid the traffic congestion.

Overnight 14th St. Bridge closing

The right lane of the northbound 14th Street Bridge will be closed from 8 p.m. Friday through noon Saturday for work on one of the bridge piers. The closing will start on the Virginia side, 200 feet before the operator’s tower.

Drivers coming up the ramp from the northbound George Washington Parkway will need to merge left almost immediately.

BW Parkway

Resurfacing and repairs will continue on the Baltimore-Washington Parkway between the D.C. line and the Annapolis Road (Route 450 interchange till about mid-August.

From 7:30 p.m. to 5:30 a.m. Friday through Sunday nights, expect to find the ramp closed from the northbound parkway to Route 202. Flaggers will allow emergency vehicle access to Prince George’s Hospital.

From 7:30 p.m. to 5:30 a.m. Sunday through Thursday nights, expect single lane closings on both sides of the parkway.

Graffiti removal

NASA will be removing graffiti from the bridge over the Baltimore-Washington Parkway near the Goddard Space Center on Saturday. One lane of the northbound parkway will be closed from about 6 to 11 a.m. and a southbound lane will then be closed till about 4 p.m.

I-95 roadblocks

From 5 to 8 a.m. Sunday, drivers may encounter rolling roadblocks and slow traffic on both sides of Interstate 95 between Exits 150 and 148 in the Dumfries/Triangle area of Prince William County.

Dominion Virginia Power will be using a helicopter to remove four aerial marker balls attached to overhead utility lines over I-95.

C&O Canal

Repairs continue on the retaining wall for the C&O Canal towpath, and that requires periodic closures of all parking areas across from the Old Angler’s Inn on MacArthur Boulevard, the National Park Service says.

Vehicles generally are prohibited from 5 a.m. to 5 p.m. daily in the upper lot and the lower drop-off lot.

Limited parking is available after 5 p.m. Alternative parking is available at Carderock, which is two miles east, and at Great Falls, 2.2 miles west. The project is scheduled to be done this fall.

Route 355 paving

Resurfacing continues at the intersection of Route 355 (North Frederick Road) and Route 27 (Ridge Road) in Germantown. Northbound Route 355 will be closed between Henderson Corner Road and Route 27 from 8 p.m. Friday to 5 a.m. Monday.

I-66 lane closings

Westbound I-66 between Route 267 and Route 7 is scheduled to close again from 11 p.m. Friday to 5 a.m. Saturday. The Dulles Metrorail project has been working on the Silver Line bridge that crosses the highway.

17th Street levee

Work will continue on the levee on both sides of 17th Street just south of Constitution Avenue NW for about 60 days, the National Park Service says. The southbound lanes of 17th Street have been closed to traffic. The northbound lanes have been converted to handle one lane of traffic in each direction. The levee project should be done in late 2012.

Manassas bridge

There’s a new traffic pattern at Nokesville and Wellington roads in Manassas, where the Virginia Department of Transportation is building a bridge over Wellington Road and the railroad tracks.

With the new pattern, northbound traffic on Nokesville Road goes over the bridge. Traffic heading to Wellington Road from northbound Nokesville Road turns right onto the new Wellington Road Connector just before crossing the bridge. Traffic heading to northbound Nokesville from Wellington Road turns onto the new connector just east of the bridge.
