US Route Map

"American streets are not sober little walks closed in between houses, but national highways. The moment you set foot on one of them, you understand that it has to go on to Boston or Chicago."
—Jean-Paul Sartre

Original Maryland US Routes, 1926
Most Maryland US routes have been around from the beginning of the US highway system in 1926. Only 29 and 301 were missing from that original plan. US 29 would be added in 1934, and 301 arrived soon after completion of the Potomac River Bridge in 1940, replacing MD 3. US 219 ended at US 40 in Grantsville. The part running south of 40 to Oakland into West Virginia was MD 37.

Early Changes
In 1938, Pulaski Highway, the new US 40 was completed, replacing the two lane road which is now Route 7. Two years later, the Choptank River Bridge was opened, bringing US 213 to Cambridge and off its original inland route.

Postwar Growth
In 1949, in preparation for the Bay Bridge to be completed in 1952, US 50 took over 213's routing to Ocean City. Around 1959, US 301 was shifted east, away from Baltimore, onto US 50 across the Bay Bridge to where it is now, formerly MD 71.

The Interstates Take Over (?)
The Interstate system, was to take over almost entirely the 111 and 240 corridors, but the end for these routes didn't come immediately. US 111 was the first to go in 1963. Old US 111 was replaced by, and partially rerouted onto, I-83. The entirety of the old route designated MD 45. US 240 was next in the early seventies, to be replaced by I-270; the old route became MD 355. US 140 had not yet been replaced by an Interstate (the Baltimore County section of it would be by 1988) but it was only 120 miles long. AASHTO, the body which coordinates US and Interstate numbers, established a guideline which stated US routes should either be at least 500 miles long and/or interstate (small i). Although 140 met the latter, Maryland and Pennsylvania agreed to decommission 140 in 1979. The ruling would also mean the end of what was left of 213 between Elkton and Wye Mills after 50 took most of its length in 1949. US 50 between Washington and Annapolis was to be designated I-595, but people were used to 50, and dual signage considered a waste of money. Its is referred to as 595 only in official state and federal documents.

US 313?
Was 313 ever a US route? As far as I know, the answer is no. But it's shown as MD 313 on maps all the way back to 1933. It may have been suggested for inclusion in the original US route system, but rejected, or perhaps an alternative inland routing for 213.
