Easton Parkway was constructed as a western bypass of Easton in the 1960s. MD 33 was moved from Washington Street to the part of the bypass north of present MD 33 when that section of Easton Parkway opened in 1965. MD 322, which was assigned to the southern part of Easton Parkway, replaced MD 33 on Bay Street between Easton Parkway and Washington Street, the latter of which became a northern extension of MD 565. In 1978, MD 322 was assigned to all of Easton Parkway and MD 33 assumed its present eastern terminus. The Knapps Narrows drawbridge was replaced by a new drawbridge in 1998. The 1934 drawbridge was transferred to the entrance of the Chesapeake Bay Maritime Museum in Saint Michaels.
