Thomas Viaduct, Baltimore Maryland - Second day with the Mavic Mini
The Thomas Viaduct spans the Patapsco River and Patapsco Valley between Relay, Maryland and Elkridge, Maryland, USA. It was commissioned by the Baltimore and Ohio Railroad (B&O); built between July 4, 1833, and July 4, 1835; and named for Philip E. Thomas, the company's first president.
At its completion, the Thomas Viaduct was the largest railroad bridge in the United States and the country's first multi-span masonry railroad bridge to be built on a curve. It remains the world's oldest multiple arched stone railroad bridge. In 1964, it was designated as a National Historic Landmark. In 2010, the Viaduct was designated as a National Historic Civil Engineering Landmark by the American Society of Civil Engineers.
The viaduct is now owned and operated by CSX Transportation and still in use today, making it one of the oldest railroad bridges still in service.

THOMAS VIADUCT DRONE
Opened in 1835, the Thomas Viaduct was the first multiple-arch, stone railroad viaduct in the United States. The viaduct is composed of eight arches each with a clear span of about 58 feet. The viaduct has an overall length of 614 feet and a height of about 60 feet above the Patapsco River. The viaduct was constructed for the Baltimore and Ohio Railroad and is named in honor Philip E. Thomas, who served from 1827 to 1836 as the first president of the B&O. The viaduct was designed by civil engineer Benjamin Henry Latrobe, Jr. who held the position of assistant engineer of the B&O. In the early 1830s, the Baltimore and Ohio Railroad began planning what would become the first rail line into the Nation's capital. The route from Baltimore to Washington D.C. required crossing the Patapsco River and surrounding plain at Elkridge and Relay, Maryland, with a structure of sufficient elevation and strength to avoid potential damage from flooding of the river. Further, the crossing required a curved railway alignment with a radius of about 1273 feet and an arc of 4.5 degrees, substantially complicating the design and construction of the viaduct.
In order to accommodate the curved alignment without skew arches, Latrobe adopted piers that were trapezoidal in plan. The width of the piers on the outside of the curve is greater than the width along the inside of the curve, and the lateral sides of the piers follow radial lines. Construction of the viaduct under difficult site conditions was undertaken by builder John McCartney with supervision by Caspar Wever, chief of construction for the B&O. A monument in the shape of an obelisk was erected at the east end of the viaduct, commemorating the directors of the B&O, and the designers and builders of the viaduct. During its construction the viaduct became known as Latrobe's Folly as many expected it would never be able to support its own weight of 63,000 tons of granite. However, upon its successful completion in 1835, the American Railroad Journal recognized its engineering significance by declaring it a university for the design and construction of railroad bridges. The uniqueness of Latrobe's design is noted in the 1888 edition of Mahan's Treatise on Civil Engineering as one of the few existing bridge structures with a curved axis. The strength of Latrobe's design would be demonstrated in 1866 when the viaduct survived a major flood of the Patapsco River, which essentially destroyed the nearby Patterson Viaduct, an earlier B&O stone arch bridge designed and built by Wever and McCartney.
Throughout its history, the Thomas Viaduct has provided a critical rail link to Washington D.C. As part of the only rail line into the capital during the Civil War, the viaduct was heavily guarded by Union troops. Also provided shelter for excaped slaves for the underground railroad. The Thomas Viaduct continues to carry freight trains of substantially greater weight than those for which it was originally designed, as well as passenger trains between Baltimore and Washington.

“These people saved the world” – The Story of Loudon Park National Cemetery
“These people saved the world. They saved the WORLD.” – Shawn Graham, public affairs specialist, National Cemetery Administration.
Loudon Park National Cemetery, originally a military cemetery located within the private Loudon Park Cemetery, is located in southwest Baltimore, Md. It was one of the 14 original national cemeteries established under the National Cemetery Act of July 17, 1862.
Loudon Park National Cemetery was established in 1862 with most of the original interments coming from Baltimore hospitals, as well as the Relay House and Elkridge Landing. The Relay House was a popular hotel for B&O passengers in the 19th century. Located on the mainline route, Union regiments occupied the town of Relay beginning in May 1861. The Relay House became the headquarters for Union officers and enlisted men stationed in the area to protect the railroad from Confederate saboteurs. Elkridge Landing was another important Maryland transportation center at risk of enemy occupation or destruction during the war. Not only was Elkridge Landing a deep-water port in use since the Colonial period, but the Annapolis & Elkridge Railroad ran through it as a vital link to the B&O, iron mines and furnaces.
The cemetery is bounded by an iron fence with formal cast-iron gates at the entrance; a two-story folk Victorian lodge was built in the 1890s. Loudon Park National Cemetery was placed on the National Register of Historic Places in 1996.
