The Washington Monument is an obelisk on the National Mall in Washington, D.C., built to commemorate George Washington, a Founding Father of the United States, victorious commander-in-chief of the Continental Army from 1775 to 1783 in the American Revolutionary War, and the first President of the United States from 1789 to 1797. Standing east of the Reflecting Pool and the Lincoln Memorial, the monument is made of bluestone gneiss for the foundation and of granite for the construction. The outside facing consists, due to the interrupted building process, of three different kinds of white marble: in the lower third, marble from Baltimore County, Maryland, followed by a narrow zone of marble from Sheffield, Berkshire County, Massachusetts, and, in the upper part, the so-called Cockeysville Marble. Both "Maryland Marbles" came from the "lost” Irish Quarry Town of "New Texas". It is both the world's tallest predominantly stone structure and the world's tallest obelisk, standing 554 feet 7+11⁄32 inches (169.046 m) tall, according to U.S. National Geodetic Survey measurements in 2013–2014. It is the tallest monumental column in the world if all are measured above their pedestrian entrances. It was the world's tallest structure between 1884 and 1889, after which it was overtaken by the Eiffel Tower, in Paris. Previously, the tallest structure was the Cologne Cathedral.
The Patapsco River mainstem is a 39-mile (63 km) river in central Maryland that flows into the Chesapeake Bay. The river's tidal portion forms the harbor for the city of Baltimore. With its South Branch, the Patapsco forms the northern border of Howard County, Maryland. The name "Patapsco" is derived from the Algonquian pota-psk-ut, which translates to "backwater" or "tide covered with froth."
Maryland Route 45 is a state highway in the U.S. state of Maryland. Known for most of its length as York Road, the state highway runs 30.06 miles (48.38 km) from U.S. Route 1 /US 40 Truck in Baltimore north to the Pennsylvania state line in Maryland Line, where the highway continues as State Route 3001. MD 45 is the primary highway between Downtown Baltimore and Towson, the county seat of Baltimore County. North of Interstate 695 (I-695), the state highway parallels I-83 and serves the suburban communities of Lutherville, Timonium, Cockeysville, and Hunt Valley. MD 45 also connects the northern Baltimore County communities of Hereford and Parkton. The state highway is maintained by the Maryland State Highway Administration in Baltimore County and by the Baltimore City Department of Transportation in the city, where the highway also follows Greenmount Avenue.
Maryland Route 99 is a state highway in the U.S. state of Maryland. Known as Old Frederick Road, the state highway runs 7.57 miles (12.18 km) from MD 32 near West Friendship east to U.S. Route 29 in Ellicott City. MD 99 parallels the north side of Interstate 70 (I-70) through a rural and suburban area in northeastern Howard County. MD 99, which follows the original 18th-century road west from Baltimore, was constructed as part of three state highways: MD 99, the original MD 100, and MD 105. All three highways were constructed between the early 1920s and early 1930s. MD 99 originally turned south along St. Johns Lane to US 40 and MD 144; in 1956, the state highway was rerouted along part of MD 100 and all of MD 105 to downtown Ellicott City. MD 99's eastern terminus was rolled back to US 29 in two steps in the late 1970s and late 1980s.

MD 145 connects the north-central and eastern portions of Baltimore County via Jacksonville. The first section of the highway was built from Loch Raven Reservoir to Jacksonville in the early 1910s. The remainder of MD 145 east to Baldwin was completed in the mid-1920s. The state highway was extended west to Cockeysville in the early 1980s in a maintenance swap. When MD 145's bridge over Loch Raven Reservoir was replaced in 2000, the old bridge from 1922 was preserved.

Tennessee marble is a type of crystalline limestone found only in East Tennessee, in the southeastern United States. Long esteemed by architects and builders for its pinkish-gray color and the ease with which it is polished, the stone has been used in the construction of numerous notable buildings and monuments throughout the United States and Canada, including the National Gallery of Art, National Air and Space Museum, and United States Capitol in Washington, D.C., the Minnesota State Capitol Grand Central Terminal in New York, and Union Station in Toronto. Tennessee marble achieved such popularity in the late-19th century that Knoxville, the stone's primary finishing and distribution center, became known as "The Marble City."
