US 340 Spur: Appeared in Maryland route logs from 1965-70 as a 0.09 spur from US 340 to Sandy Hook Rd. It was a horseshoe shaped road leaving US 340 just east of the Potomac River bridge, curling up and around down to Sandy Hook Rd (old US 340) which passes under the bridge.
The road itself goes back to atleast 1955 (aerials) and possibly to the bridge construct around 1950.
In 1971, the route logs changed the designation to MD 340. Today the roadway is abandoned. I imagine it was fairly tricky to access to/from US 340.
