Chesapeake Bay Bridge (US 50/301). The William Preston Lane, Jr., Memorial Bridge (Chesapeake Bay Bridge) spans 4.3 miles across the middle of Chesapeake Bay. Opened in 1952 as a two-lane structure, the Bridge transformed access to Maryland's Eastern Shore. A three-lane parallel bridge opened in 1973. For passenger vehicles traveling east, a $6.00 toll is collected electronically in Anne Arundel County on the Western Shore (lower for E-ZPass users; higher for vehicles with 3 or more axles).
As the Susquehanna River Toll Bridge, the Hatem Memorial Bridge opened in 1940. In 1986, it was renamed for Thomas J. Hatem (1925-1985) who represented Harford County in the House of Delegates from 1955 to 1958.

Francis Scott Key Bridge (I-695).
Opened on March 23, 1977, the four-lane Francis Scott Key Bridge was named for Francis Scott Key (1780-1843), who wrote "The Star Spangled Banner" following the British attack on Baltimore, September 13, 1814. Part of the Baltimore Beltway (I-695), the Key Bridge extended 1.6 miles across Baltimore Harbor. At about 1:30 a.m. on March 26, 2024, the Key Bridge was struck by the cargo ship Dali and collapsed, killing six construction workers.

Tolls were collected electronically for both north and southbound traffic at the Key Bridge. Electronic toll-collection (known as M-TAG) began for the Key Bridge in 1999. In January 2003, M-TAG became part of the E-ZPass system. Two-axle vehicles electronically paid $6.00 each way (lower for E-ZPass users; higher for vehicles with 3 or more axles).

Governor Harry W. Nice Memorial/Senator Thomas (Mac) Middleton Bridge (US 301). The Governor Harry W. Nice Memorial Bridge (Potomac River Bridge) opened in December 1940 as the Potomac River Toll Bridge. In 1967, it was renamed for Harry W. Nice (1877-1941) who served as governor of Maryland from 1935 to 1939. In 2018, the name of Thomas M. (Mac) Middleton, a State Senator, was added to the bridge. In October 2022, a new bridge opened to replace the original one, which will be demolished.
