Many outdoor events are scheduled for this weekend in the D.C. area. Travelers will find the heat less intense than the past few days, but the chance of thunderstorms higher, the Capital Weather Gang says. That shouldn’t interfere with plans for the Capital Pride parade and festival in the District, the Air Force Cycling Classic in Clarendon and Crystal City or the Celebrate Fairfax festival at the Fairfax County Government Center.

Air Force Cycling Classic

On Saturday, cycling events are scheduled from 8 a.m. to noon, when the Clarendon Cup starts. See a course map. Clarendon, on the Orange Line, is the nearest Metro stop.

Sunday is the day for the Crystal Cup Men’s Pro, Women’s Elite and Amateur races, starting at 11:30 a.m. at the U. S. Air Force Memorial. See a pdf course map.

Crystal City, on the Blue Line, is the nearest Metrorail stop. Check the Metrorail maintenance schedule below for weekend service details.

Capital Pride parade

The annual Capital Pride parade starts at 5:30 p.m. Saturday at P and 22nd streets NW, goes around Dupont Circle and up New Hampshire Avenue, tuns right on R Street, then right again at 17th Street back to P Street, where it turns left, then right on 14th Street to its end at N Street. See a map. The event should wrap up about 8:30 p.m. The nearest Metro station is Dupont Circle. That’s on the Red Line, so check Metro’s weekend maintenance schedule below.

Celebrate Fairfax

The hours for the annual festival are 6 p.m. to midnight Friday, 10 a.m. to midnight Saturday and 11 a.m. to 7 p.m. Sunday. See a map of the festival grounds.

A free shuttle to the festival stops at Fair Oaks Shopping Center and on Fair Lakes Circle. See a pdf map for the shuttle system

Metro weekend delays

Maintenance work will disrupt Metrorail travel on the Blue, Orange and Red lines this weekend.

Red Line: From 9:30 p.m. Friday through the midnight closing Sunday, trains will share a track between Grosvenor and Twinbrook stations. Crews will be working on the platforms at White Flint and Twinbrook.

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

Throughout the weekend, trains will leave the ends of the line at Shady Grove and Glenmont about every 24 minutes. Service will be more frequent on the inner portion of the line, between Grosvenor and Takoma. Trains on that stretch are scheduled to arrive about every 12 minutes.

Blue/Orange lines: From 10 p.m. Friday to closing Sunday, trains will share a track between Foggy Bottom and Arlington Cemetery and between Foggy Bottom and Clarendon. Workers will be replacing rail fasteners.

Throughout the weekend, all Blue and Orange Line trains will be scheduled to leave the ends of the lines about every 20 minutes.

Beltway/Telegraph Road

The Wilson Bridge project, which is rebuilding the Telegraph Road interchange and widening the Beltway nearby, will be placing new signs this weekend before the LOCAL/THRU split on the outer loop to simplify the message motorists see as they head toward the Wilson Bridge.

The signs will tell drivers that all lanes go through to destinations beyond the construction zone after the lane split, according to an announcement from the project. The signs also will alert motorists who want the local exits that they should stay right.

This area of the Beltway is in flux, because of the construction project, and the signs are temporary, but if they work as the planners intend, they should eliminate at least some of that last-moment lane changing at the split and thereby improve traffic flow.

The new sequence of signs will first appear just after the outer loop’s Van Dorn interchange and then at regular intervals up to the split, just east of Telegraph Road.

Signs notifying travelers that all lanes go through to destinations beyond the construction area will be in black letters and symbols on yellow and orange backgrounds, the project staff said. Messaging to keep right to take local exits will be in white letters on black backgrounds.

Starting at 9 p.m. Friday, one THRU lane will be closed, leaving two LOCAL open; the ramps to the outer loop from Telegraph Road North and South will remain open. Starting at 9 p.m. Saturday, one THRU lane and one LOCAL lane will be closed, leaving only one LOCAL lane open to traffic. Traffic will be constricted to one lane until 9 a.m. Sunday, when all lanes will reopen and traffic movement will be fully restored. Project managers advise drivers to avoid the area during the work, because of the likely congestion.

Metro art at Takoma

The transit authority will dedicate new public art — a large mosaic mural by Sam Gilliam called “From a Model to a Rainbow,” at Takoma Metrorail station in a ceremony at 10 a.m. Saturday. (Takoma is on the Red Line, so be sure to check the Red Line track work schedule listed above.)

Beltway/Northwest Branch

Drivers can see “Photo Enforced” in an orange-and-black addition to the 55 mph speed limit signs near the Capital Beltway’s Northwest Branch bridge in Silver Spring. Maryland doesn’t have a start date for the camera enforcement program in this new work zone, and the the signs were supposed to remain covered until an official announcement.

Drive as though you were already on camera. Workers have been setting up the lane shifts for fast-moving traffic to flow through a tight work zone with lots of signs, barriers and barrels. The Beltway is vital to commuters, so the highway administration is planning to do the necessary bridge deck rehabilitation while maintaining eight lanes of traffic at rush hours. The project is scheduled to be done in spring 2013.

Anacostia Freeway

Drivers are encountering traffic delays as the District Department of Transportation repairs bridges along the Anacostia Freeway (Interstate 295). The work is being performed on five freeway bridges: over the Anacostia Park entrance, over Howard Road, over Suitland Parkway, over Firth Sterling Avenue and over South Capitol Street.

The repair work, which will continue through September, requires single lane closings along the freeway. The department says it will keep two lanes open in each direction.

Here’s the work schedule on the bridges.

Firth Sterling Avenue: through June 23.

Anacostia Park entrance: June 24 through July 5.

Howard Road: July 6 through July 29.

Suitland Parkway:July 30 through Aug. 25.

South Capitol Street: Aug. 26 through Sept. 30.

U.S. Open

The U.S. Open, scheduled to start with practice rounds Monday at Congressional Country Club in Potomac, could draw a quarter-million spectators. Tournament play is Thursday through next Sunday. The best way to get there will be via shuttle buses. (Travelers note that the shuttle from the Grosvenor Metro station costs $8 while the shuttles from various parking areas are free to ticket holders.) But I think I might pay the $8 for the shorter ride to the Open from Grosvenor. The parking areas are in Gaithersburg and at Dulles International Airport

See our U.S. Open travel guide here.

Beltway/Tysons Corner

Watch for multiple lane closings overnights next week on the Beltway’s inner loop at Route 123. This is where the Dulles Metrorail line is coming over the Beltway.

The three right through lanes are scheduled to close Wednesday and Thursday nights from 11 p.m. to 5 a.m. Traffic will be allowed to pass through the interchange, but drivers can expect delays. Lanes will begin to taper down near Route 7 (Leesburg Pike).

The two left lanes on both loops will be closed next Friday, June 17, from 10:30 p.m. to 7 a.m. All ramps to and from Route 123 will remain open.

Bethesda BRAC planning

Work continues near the Bethesda National Naval Medical Center to prepare for the arrival of new employees and patients from Walter Reed Army Medical Center in September that is part of the national military base realignment program.

Rehabilitation of the bridge on Cedar Lane over Rock Creek is continuing, Montgomery County transportation officials say. The bridge will be closed to vehicular traffic beginning at 7 p.m. Thursday and remain closed through Aug. 24.

Pavement patching, milling and resurfacing has begun on Battery Lane from Old Georgetown Road to Wisconsin Avenue. This project should be complete by the end of June, weather permitting.

A new sidewalk is being constructed along Jones Bridge Road. One segment has opened from Wisconsin Avenue through Gunnell Road. Construction of a sidewalk between Gunnell Road and Grier Road is scheduled to start soon.

Sidewalk construction along Wisconsin Avenue beside the medical center has been completed.
