US 340 crossing the Potomac River just east of Harpers Ferry; the Shenandoah River joins the Potomac in the background. US 340, which runs through Virginia for about a mile after this, turns from east-west to north-south once it leaves Maryland.


Where I-270 begins, so does US 340. US 40 hops onto I-270 via US 15, with MD 144 following old US 40 through Frederick. US 340 begins multiplexed with US 15 for several miles because it starts at 40. Old 340 (Jefferson St.) flows into new 340 here from 144, and the old Jefferson Pike (MD 180) starts up again just to the north.
Oh, yeah, notes on the photos. Too much space above the I-70 shield. Fonts too bold in the 40 and 15 shields. Odd-looking exit sign. That should keep you happy.


US 15 SB where it's about to pick up US 40, and some very very strange spacing decisions.


Say goodbye to Waffle Houses and NASCAR! US 15 NB.
