Interstate 270 Spur

Home » Guides » Maryland » Interstate 270 Spur

Officially Interstate 270Y, the 2.10 mile route of I-270 Spur links Interstates 270 and 495 in Montgomery County. The route of I-270 takes the freeway southeast to a wye interchange, with access onto I-495 east (inner) and from I-495 west (outer). I-270 Spur provides access to I-495 south (outer) into Northern Virginia and from I-495 north (inner).

Interstate 270 Spur came into existence when Interstate 270 was designated in place of Interstate 70S in 1973. Before that transition, the spur route was the entirety of I-270. It should be noted also that a late 1970s official Virginia map showed the spur as I-470.
