Millard E. Tydings Memorial Bridge

Millard E. Tydings Memorial Bridge is a major cantilever bridge that carries Interstate 95 and the John F. Kennedy Memorial Highway across the Susquehanna River in northeastern Maryland. It connects the towns of Havre de Grace in Harford County and Perryville in Cecil County, serving as a critical link in the East Coast transportation corridor. The bridge is named for longtime United States Senator Millard Tydings and is owned and operated by the Maryland Transportation Authority.

History

The bridge's construction was driven by the post-war expansion of the Interstate Highway System and the need to replace the aging, two-lane Havre de Grace Bridge. Planning accelerated following the passage of the Federal-Aid Highway Act of 1956, which provided federal funding for projects like the John F. Kennedy Memorial Highway. The structure was dedicated to Millard Tydings, a prominent Democratic senator from Maryland who served from 1927 to 1951 and was a key figure in New Deal legislation and military affairs. Its opening in 1963 completed a vital segment of Interstate 95 between Baltimore and Wilmington, Delaware.

Design and construction

Engineered as a steel cantilever bridge, the structure has a main span of and a total length of . The design was executed by the Maryland State Roads Commission, with the superstructure fabricated and erected by the American Bridge Company. Construction began in 1960 and involved innovative techniques for the era, including the use of large prefabricated sections. The bridge's piers are founded deep in the bedrock of the Susquehanna River, and its deck was designed to accommodate the future widening of Interstate 95, which was later realized.

Tolls and operations

The bridge is a key revenue-generating facility for the Maryland Transportation Authority, collecting tolls for northbound traffic only. It originally utilized a barrier toll plaza on the Perryville side, but this was reconfigured to all-electronic tolling (E-ZPass and Video Tolling) in 2020 as part of a system-wide modernization. Revenue supports the maintenance of this bridge and other authority assets like the Fort McHenry Tunnel and the Chesapeake Bay Bridge. The toll rate is set by the authority's board and is consistent with other major crossings in the state.

Incidents and closures

The bridge has experienced several significant incidents requiring full or partial closures. A major collision and fire involving multiple tractor-trailers in 1986 caused extensive damage to the deck, leading to a prolonged closure for repairs. In 1996, a fatal accident involving a tanker truck carrying hazardous materials prompted a large-scale emergency response and a lengthy shutdown. Routine inspections have also led to temporary lane restrictions, such as those for steel fatigue checks conducted by the Federal Highway Administration. Severe weather events, including Hurricane Isabel in 2003, have also necessitated precautionary closures due to high winds.

Cultural significance

As the most visible crossing of the Susquehanna River in Maryland, the bridge is a regional landmark and a symbol of interstate connectivity. It is frequently featured in media coverage of traffic conditions on the Northeast Corridor by outlets like WJZ-TV and the *Baltimore Sun*. The structure also holds a place in transportation history, representing the engineering ambitions of the mid-20th century and the political legacy of Millard Tydings. Its presence has influenced economic development in both Cecil County and Harford County, facilitating commuter patterns and commercial freight movement.
