Since its construction, the bridge has made significant impacts on both sides of the bay; among them has been the growth of Eastern Shore communities. When the bridge opened in 1952, and again when the second span was added in 1973, the Eastern Shore was given easier access to Baltimore and Washington, causing areas in southern Queen Anne's County to develop as bedroom communities. This extension of the Baltimore–Washington suburbs has led Queen Anne's County to be listed as part of the Baltimore–Washington Metropolitan Area. The bridge has also given easier access to Ocean City from the Western Shore, which has caused Ocean City to grow from a small town to one that is said to become the second largest city in Maryland during the summer.
