Oldest Bridges in The US
1. The Frankford Avenue Bridge, Pennsylvania
Built in 1697, the Frankford Avenue Bridge over Pennypack Creek in Philadelphia is considered the oldest continuously used roadway bridge in the United States. Originally constructed by the British, its three beautiful stone arches have been strengthened and widened over the centuries to accommodate modern traffic.
This bridge not only serves as a vital passageway but also as a reminder of colonial engineering and early American development. Its historical significance has been recognized with a National Historic Civil Engineering Landmark designation.
The bridge’s enduring nature speaks to the lasting impact of well-thought-out design and construction.
2. The High Bridge, New York
The High Bridge across the Harlem River, completed in 1848, is New York City’s oldest standing bridge. Originally part of the Croton Aqueduct system, it was designed as a stone and steel arch structure to carry water to the city.
Following a period of disuse and subsequent renovation, it now serves as a pedestrian walkway offering scenic views of the river and surrounding areas. Its transformation from a crucial component of the city’s early water supply system to a cherished public space exemplifies adaptive reuse.
The High Bridge stands as a testament to New York’s rich history and its evolution over the centuries.
3. The Piscataqua River Bridge, New Hampshire
Connecting New Hampshire to Maine, the Piscataqua River Bridge, also known as the John Paul Jones Memorial Bridge, was completed in 1828. This timber pile structure represented a significant achievement in early 19th-century bridge construction. Although it has undergone numerous renovations to support modern vehicles, the bridge maintains its historic charm and significance.
It’s a symbol of the engineering feats that were possible even in the early days of the United States, connecting not just two states but also the people who live within them. This bridge illustrates the importance of transportation and communication in the growth of the country.
4. The Old Blenheim Bridge, New York
Before its destruction by a flood in 2011, the Old Blenheim Bridge was an iconic symbol of 19th-century American engineering. Built in 1855, it was the longest single-span wooden covered bridge in the world, stretching 210 feet across Schoharie Creek. Its design showcased the ingenuity of American wood construction techniques of the time, offering both functionality and aesthetic appeal.
Even though it no longer stands, the bridge’s legacy continues to inspire modern engineers and historians alike. Efforts to rebuild the bridge have been undertaken, highlighting the community’s desire to preserve and celebrate their historical landmarks.
5. The Humpback Bridge, Virginia
Tucked away in the lush landscapes of Virginia, the Humpback Bridge offers a picturesque view into the past. Constructed in 1857, this is the oldest of Virginia’s remaining covered bridges and is distinctive for its humpback design—a unique feature that gives the bridge its name. Originally built to facilitate the transport of goods and people across Dunlap Creek, it now serves as a scenic spot hidden away from the hustle and bustle of modern life.
The bridge’s enduring beauty and craftsmanship attract visitors from all over, making it a beloved historical site and a testament to the longevity of traditional construction methods.
6. The Bollman Truss Railroad Bridge, Maryland
Situated in Savage, Maryland, the Bollman Truss Railroad Bridge is an important relic of the industrial age and a significant piece of civil engineering history. Constructed in 1869, it is the only surviving example of a revolutionary design in metal bridge technology—the Bollman truss. This design was crucial in the development of iron railroad bridges in the United States, showcasing the shift from wood to iron in bridge construction.
Today, it stands as a testament to the innovative engineering spirit of the 19th century, providing insight into the evolutionary stages of bridge building.
7. The Smithfield Street Bridge, Pennsylvania
The Smithfield Street Bridge in Pittsburgh is a prime example of the beauty and enduring nature of wrought iron construction. Completed in 1883, it is the oldest steel bridge in the United States and an iconic symbol of Pittsburgh’s industrial past. Its innovative use of lenticular trusses has made it a subject of study for engineering students and professionals alike.
The bridge’s elegant design and historical significance have earned it a place as a National Historic Civil Engineering Landmark. It continues to serve as a vital transportation link, embodying the city’s rich history and its transition into modernity.
8. The Covington-Cincinnati Suspension Bridge, Kentucky/Ohio
Connecting Kentucky and Ohio across the Ohio River, the Covington-Cincinnati Suspension Bridge, more commonly known as the Roebling Suspension Bridge, predates the famous Brooklyn Bridge and was completed in 1866. Designed by John A. Roebling, it served as a prototype for his later work on the Brooklyn Bridge.
Its striking architecture and engineering innovations set a precedent for future suspension bridges, making it a pivotal structure in the history of American bridge construction. This bridge not just facilitates cross-river traffic but also stands as a landmark achievement in the realm of civil engineering.
9. The Longfellow Bridge, Massachusetts
Linking Boston to Cambridge over the Charles River, the Longfellow Bridge is a combination of utility and artistry. Completed in 1907, it is renowned for its distinctive Beaux-Arts style, earning it the nickname “The Salt and Pepper Bridge” due to its uniquely designed towers.
Beyond its aesthetic appeal, the bridge has served as a critical artery for both vehicular and public transit, specifically the Massachusetts Bay Transportation Authority’s Red Line. Its enduring presence over the Charles River speaks to the blend of functionality and design that characterizes the best of American infrastructure.
