Maryland Route 189 (MD 189) is a state highway in the U.S. state of Maryland. Known as Falls Road, the highway runs from MD 190 in Potomac to Great Falls Road and Maryland Avenue in Rockville. MD 189 connects Rockville with Potomac and the Great Falls of the Potomac River in southwestern Montgomery County. The highway was constructed from Rockville to Potomac by the early 1920s and extended toward Great Falls in the early 1930s. MD 189 was expanded to a divided highway around its newly-constructed interchange with Interstate 270 (I-270) in the late 1980s. The highway was truncated at both ends in the late 1990s. Route description MD 189 begins at an intersection with MD 190 (River Road) in the village center of Potomac. Falls Road continues south as a county highway to MacArthur Boulevard and the entrance to the Chesapeake and Ohio Canal National Historical Park, which includes the Great Falls of the Potomac.

Chesapeake And Ohio Canal National Historical Park
The Chesapeake and Ohio Canal National Historical Park is located in the District of Columbia and the state of Maryland. The park was established in 1961 as a National Monument by President Dwight D. Eisenhower to preserve the neglected remains of the Chesapeake and Ohio Canal and many of its original structures. The canal and towpath trail extends along the Potomac River from Georgetown, Washington, D.C., to Cumberland, Maryland, a distance of . In 2013, the path was designated as the first section of U.S. Bicycle Route 50. The Chesapeake and Ohio Canal Construction on the Chesapeake and Ohio Canal (also known as "the Grand Old Ditch" or the "C&O Canal") began in 1828 and ended in 1850 when the canal reached Cumberland, far short of its intended destination of Pittsburgh, Pennsylvania. Occasionally there was talk of extending the 184.5-mile canal: for example, an 1874 proposal to dig an 8.4-mile tunnel through the Allegheny Mountains, and there was a tunnel built to connect with ...

Single-point Urban Interchange
A single-point urban interchange (SPUI, or ), also called a single-point interchange (SPI) or single-point diamond interchange (SPDI), is a type of highway interchange. The design was created in order to help move large volumes of traffic through limited amounts of space safely and efficiently. Description A SPUI is similar in form to a diamond interchange but has the advantage of allowing opposing left turns to proceed simultaneously by compressing the two intersections of a diamond into one single intersection over or under the free-flowing road. The term "single-point" refers to the fact that all through traffic on the arterial street, as well as the traffic turning left onto or off the interchange, can be controlled from a single set of traffic signals. Due to the space efficiency of SPUIs relative to the volume of traffic they can handle, the interchange design is being used extensively in the reconstruction of existing freeways as well as constructing new freeways, p ...

C&O Canal Scenic Byway
The Maryland Scenic Byways system consists of nineteen byways that pass through scenic and historic areas across the U.S. state of Maryland, with four of them designated as National Scenic Byways and two of them designated as All-American Roads. The byways pass through a variety of surroundings, such as the mountains of Western Maryland, the rolling countryside in the northern part of the state, urban sites in the Baltimore and Washington, D.C. areas, small towns and wildlife areas along the Chesapeake Bay, and beaches along the Atlantic Ocean. The byways also serve historical sites ranging from colonial settlement, the War of 1812, and the American Civil War, along with byways that follow the historic routes of the National Road, the Chesapeake and Ohio Canal, and the Underground Railroad. Historic National Road The Historic National Road Scenic Byway travels from Keysers Ridge to Baltimore along the historic route of the National Road, a road that connected Baltimore to V ...

The western portion of MD 28 is a rural highway connecting several villages in southern Frederick County and western Montgomery County. By contrast, the eastern portion of the state highway is a major east–west commuter route, particularly within Gaithersburg and Rockville. MD 28 was an original 1927 Maryland state highway. The state highway originally extended north and east through Olney to Ashton, but the highway was rolled back to Norbeck in the 1940s. MD 28 was extended east to its present eastern terminus in the early 1980s. The original western terminus was in Tuscarora, but the state highway was extended to Point of Rocks around 1970. In addition to being expanded to a multi-lane divided highway in central Montgomery County beginning in the 1970s, MD 28 was relocated in downtown Roc ...

Macadam
Macadam is a type of road construction, pioneered by Scottish engineer John Loudon McAdam around 1820, in which crushed stone is placed in shallow, convex layers and compacted thoroughly. A binding layer of stone dust (crushed stone from the original material) may form; it may also, after rolling, be covered with a cement or bituminous binder to keep dust and stones together. The method simplified what had been considered state-of-the-art at that point. Predecessors Pierre-Marie-Jérôme Trésaguet Pierre-Marie-Jérôme Trésaguet is sometimes considered the first person to bring post-Roman science to road building. A Frenchman from an engineering family, he worked paving roads in Paris from 1757 to 1764. As chief engineer of road construction of Limoges, he had opportunity to develop a better and cheaper method of road construction. In 1775, Tresaguet became engineer-general and presented his answer for road improvement in France, which soon became standard practice there. ...
