Road work and special events may delay your travels this week. Here is a look at some of the activities that may slow you down.

U.S. Open traffic

The U.S. Open, scheduled to start with practice rounds Monday at Congressional Country Club in Potomac, could draw a quarter of a million spectators. Tournament play is Thursday through 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.

Here is a look at the parking and transportation options, along with a list of banned items.

Beltway/Telegraph Road

New signs may help drivers on the Capital Beltway’s outer loop identify where they want to be before they reach the split for the LOCAL and THRU lanes as they approach the Woodrow Wilson Bridge in Virginia.

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

This area of the Beltway just west of the bridge is in flux because of the construction project, and the signs are temporary. But if they work as the planners on the Woodrow Wilson Bridge project intend, they should eliminate at least some of that last-moment lane changes 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.

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.

Beltway/Tysons Corner

Watch for multiple lane closings overnights this 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 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 near Route 7 (Leesburg Pike).

The two left lanes on both loops will be closed Friday 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 and Closing 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 have 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 — from Wisconsin Avenue through Gunnell Road — has opened. 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.
