Crisfield's prosperity began to decline along with the health of the Chesapeake Bay. Oyster populations declined to the point where the watermen could no longer fully support themselves on their daily catches. Some businesses began to move out of Crisfield, while others shut down. On April 1, 1976, the railroad that had brought prosperity to Crisfield was abandoned as Conrail was established. However, Maryland Route 413, a new, straight vehicular highway was built before the railroad was abandoned, along the railroad right-of-way. As large businesses in the United States grew, they passed the shrinking Crisfield by until the late 20th century. Fast-food restaurants began to slowly find business in the city, starting in the late 1990s, alongside the many seafood restaurants already in town. A large supermarket had been in city plans for a decade, though it wasn't until April 2010 that it opened for business. Crisfield has also been a target for large waterfront properties, with several large condominiums being built in the mid-2000s in the downtown area, along with other places flanking Crisfield's harbors. A "strategic revitalization plan" has been in the works since 2006 to address future growing needs and beautification of the city.
