Streets and roads

Main articles: Streets and highways of Arlington County, Virginia and Arlington County, Virginia, street-naming system

Arlington forms part of the region's core transportation network. The county is traversed by two interstate highways, Interstate 66 in the northern part of the county and Interstate 395 in the eastern part, both with high-occupancy vehicle lanes or restrictions. In addition, the county is served by the George Washington Memorial Parkway. In total, Arlington County maintains 376 miles (605 km) of roads.^[97]
The street names in Arlington generally follow a unified countywide convention. The north-south streets are generally alphabetical, starting with one-syllable names, then two-, three- and four-syllable names. The "lowest" alphabetical street is Ball Street. The "highest" is Arizona. Many east-west streets are numbered. Route 50 divides Arlington County. Streets are generally labeled North above Route 50, and South below.
Arlington has more than 100 miles (160 km) of on-street and paved off-road bicycle trails.^[98] Off-road trails travel along the Potomac River or its tributaries, abandoned railroad beds, or major highways, including: Four Mile Run Trail that travels the length of the county; the Custis Trail, which runs the width of the county from Rosslyn; the Washington & Old Dominion Railroad Trail (W&OD Trail) that travels 45 miles (72 km) from the Shirlington neighborhood out to western Loudoun County; the Mount Vernon Trail that runs for 17 miles (27 km) along the Potomac, continuing through Alexandria to Mount Vernon. In Fall 2015, Arlington was awarded a Silver ranking by the League of American Bicyclists for its bike infrastructure.

Public transport

Arlington is home to the first suburban Washington Metro stations

40% of Virginia's transit trips begin or end in Arlington, with the vast majority originating from Washington Metro stations.^[99]
Arlington is served by the Orange, Blue, Yellow, and Silver lines of the Washington Metro. The Metro stations in Arlington are the only stations outside of Washington, D.C. where the system's original Brutalist architecture can be found.^[100]
Additionally, Arlington is served by Virginia Railway Express commuter rail, Metrobus (regional public bus), Fairfax Connector (regional public bus), Potomac and Rappahannock Transportation Commission (PRTC) (regional public bus), and a county public bus system, Arlington Transit (ART). Metroway, the first bus rapid transit (BRT) in the D.C. area, is a joint project between the City of Alexandria, Arlington County, and the Washington Metropolitan Area Transit Authority with wait times similar to those of Metro trains; it was being implemented between Alexandria and Arlington as of July 2014.^[101]

Arlington County is home to Ronald Reagan Washington National Airport, which provides domestic air services to the Washington, D.C. area.

Several hybrid taxis at Pentagon City

In 2007, the county authorized EnviroCAB, a new taxi company, to operate exclusively with a hybrid-electric fleet of 50 vehicles and also issued permits for existing companies to add 35 hybrid cabs to their fleets. As operations began in 2008, EnvironCab became the first all-hybrid taxicab fleet in the U.S. and the company not only offset the emissions generated by its fleet of hybrids, but also the equivalent emissions of 100 non-hybrid taxis in service in the metropolitan area.^[104][105] The green taxi expansion was part of a county campaign known as Fresh AIRE, or Arlington Initiative to Reduce Emissions, that aimed to cut production of greenhouse gases from county buildings and vehicles by 10 percent by 2012.^[104]
