 Before U.S. Route 140 was deleted, it was where MD 140 is today.At the divergence of MD 140 and MD 97 northwest of Westminster, the two routes were swapped after the deletion of the U.S. route; MD 97 now follows US 140's old route to Pennsylvania, while MD 140 follows MD 97's original route to Taneytown and US 15.As a result, MD 140 follows the bypass of the original MD 32 between Westminster and Taneytown that was first designated as part of MD 97.
