Where to park and how to get to the U.S. Open

The U.S. Open golf tournament, which began Monday with practice rounds at Congressional Country Club in Bethesda, could draw 250,000 spectators. Traffic will be at its worst during tournament play through Sunday, and the best way to get there will be via shuttle buses.

Parking: Montgomery County Fairgrounds and Crown Farm

The fairgrounds is the preferred option for spectators traveling southbound on Interstate 270. Spectators traveling northbound on I-270 should park at Crown Farm, on Fields Road, south of Sam Eig Highway.

Shuttles will run continuously from 6 a.m. to 9 p.m. each day of the tournament, with transportation expected to take 25 minutes.

Drop-off area: The Norwood School

There will be no general parking or parking for spectators with disabilities in the immediate vicinity of Congressional Country Club.

The passenger, taxi and limousine drop-off location is across the street, at the Norwood School on Bradley Boulevard. The school also has been designated for bicycle parking.

Metro: Shuttle from Grosvenor

Spectators taking Metro can reserve a spot in advance on a shuttle from the Red Line’s Grosvenor-Strathmore Station by going to www.tms-llc.com.

Daily shuttle passes, good for unlimited trips, are $8. A weekly shuttle pass is $35, which will provide unlimited shuttle service through Sunday. Children 12 and younger do not need shuttle passes.

Parking: Dulles International Airport

Shuttle buses from the parking area at Dulles will use the Route 267 access road. A pass, which was available by calling the championship office before June 10, will be required to use this parking option at Dulles.

Towing: Vehicles parked illegally will be ticketed. But vehicles parked illegally along shuttle bus routes will be towed. Motorists can call 301-279-8000 to locate their towed vehicle.
