Major nearby streets include Military Road and Connecticut Avenue. To reach the campus from Military Road, turn South on 32nd street or Nevada. From Connecticut, take Military or Nebraska to Nevada. Connecticut Avenue connects to the Capital Beltway (I-495) to the north of EPL and runs to K St. in downtown Washington to the south.

From Washington Area Airports

All three Washington area airports are reasonable choices for travel to EPL by taxi or SuperShuttle.

Reagan National Airport (DCA) is approximately nine miles and 30 minutes from EPL; Dulles International Airport (IAD) is approximately 25 miles and 40 minutes; and Baltimore-Washington International (BWI) is approximately 36 miles and 50 minutes away.

Travel times are heavily dependent on traffic conditions. DCA is the only airport directly serviced by the Metro (Yellow and Blue Lines).

Via Public Transportation

EPL is approximately 1.5 miles from three Metro stations on the Red Line: Van Ness-UDC (at the intersection of Connecticut Ave. and Van Ness), Tenleytown-AU (at the intersection of Wisconsin Ave. and Albemarle), and Friendship Heights (at the intersection of Wisconsin Ave. and Western Ave.). Taxis are usually available on Connecticut Ave.

Buses are accessible from any of these Metro stations. From the Van Ness-UDC Metro, exit toward the "northbound buses" and take any "L" bus from the stop right outside the escalator. Exit the bus at Nebraska Ave. in front of Marvelous Market. Walk south to 36th St. and proceed down the hill. Turn right onto Nevada Ave. and left onto 32nd Street. Turn right at Carnegie's driveway.

If arriving at the Friendship Heights Metro, exit at the Military Road/Western Ave. Exit and board the E4 (Military Road-Crosstown line) bus on Western Ave. Take the bus to the intersection of 30th St. and Military Rd. Walk west on Military to 32nd St., and then south one block to campus.

Alternatively, take the Metro to Tenleytown and exit at the 40th Street (West) exit. Walk straight ahead and then turn left onto Abelmare St. in front of Whole Foods. Cross the street and proceed to the M4 bus stop near Wilson High School. Exit the bus at Military Road and 32nd St. Walk down the 32nd St. hill to campus.
