El Camino Real de Tierra Adentro, (English: Royal Road of the Interior Land). This royal road was also know as the Silver Route, one which was used from 1598 to 1882. This roadpath was a Spanish built road of about 1590 miles in length which traversed from Mexico City northward to Santa Fe, New Mexico and eventually as far north to San Juan Pueblo in New Mexico.

The King′s Highway was the most important road in colonial America and served as the major transportation route for the English coloniest.

Today, most of the original King′s Highway has been paved over by modern roads and highways. There are some key historical landmarks that were along the King's Highway that are preserved today and are on the National Register of Historic Places.

The Albany Post Road was officially established in 1669 when the Dutch colonists in New Amsterdam (now New York) created a post road based on trails used by the Wappinger and/or Wicopee tribes of Native Americans. In 1703, the Provincial Legislature passed a Publick Highways act and the postal road was turned into a public highway. The colonists decided to name the road Queen′s Road after Queen Anne.

Most of Albany Post Road has been renamed and updated, but a 6 mile stretch of unpaved original road still exists. This historic part of the road is called the Old Albany Post Road and it was added to the National Register of Historic Places in 1982.

Connecticut State Highway 32 (SH 32)

Originally called Mohegan Road, this roadpath was first laid out in 1670. Before this, the road was used as a Native American trail for more than a century. The original route of Mohegan Road was between New London and Norwich, Connecticut along the east side of the Thames River. In 1792, the Mohegan Road was updated and it became the first turnpike in New England and the second turnpike ever built in the United States.

The modern Route 32 dates back to the New England Interstate Routes era, which is where the road got its number. Even after Connecticut stopped using the New England Interstate Route designations, Highway 32 became a State Highway, keeping its 32 numbering.

The Boston to New York Post Road was originally mapped in 1645 by John Winthrop Junior, son of the Massachusetts Bay Colony governor and was then established in 1673.

Over time, the Boston Post Road carved out three travel routes: the upper post road, middle post road and lower post road routes. Today, these three routes of the Boston Post Road are now known as the I-95, I-91, and I-94

The oldest part of Connecticut Route 108 dates back to 1696 and was originally called the Farm Highway. It was Trumbull, Connecticut's first highway and was completed on 07 December 1696.

The modern version of Route 108 was established in 1932 and for many years the road was fairly neglected. Originally, Route 108 only went from the town of Shelton to a dead-end in Huntington village. Eventually, the road was extended in 1952 and then given three more miles in 1963.

The Forbes Road was an important trail used by colonial British forces during the French and Indian War (Seven Years′ War) in Pennsylvania. The road was named for Brigadier General John Forbes, who led the expedition to build the road. Once completed, Forbes Road was used to transport the British troops, supplies, and artillery to the French Fort Duequesne, in what is now downtown Pittsburgh, Pennsylvania.

After the Seven Years′ War, Forbes Road continued to be used and made communication and trade easier between the eastern and western parts of the Pennsylvania colony. There are several historic markers making note of Forbes Road on modern roads such as US 22, US 11, and US 522.

The Braddock Road, often associated with the historic route taken by British General Edward Braddock during the 1775 French and Indian War was a military road carved from Alexandria, Virginia towards Fort Duquesne, now known as Pittsburgh, Pennsylvania. The road was primarily based on Nemacolin′s Path, an American Indian trail widened by George Washington and subsequently used by Braddock and his army.

His route left Alexandria along the south side of the Potomac River, continued to Leesburg, Virginia, then apparently across northern Virginia on what later became the Charlestown Pike (modern Virginia State Highway 9) crossed over the Appalachian Mountains at Keys Gap and then turned north along the Shenandoah River valley to John Yesters Ferry (present day Harpers Ferry, West Virginia).

After crossing to the north side of the Potomac River, the General and his Army continued another 80 or more miles up the Potomac river valley until reaching Cumberland, Maryland. How much of their travel was done by boat, I am not sure, as the Potomac River has long been known to be navigable all the way to Cumberland, Maryland.

Then, from Cumberland, Maryland, General Braddock and his army continued on what later would become know as the National Road all the way to his destination of Fort Duquesne, Pennsylvania, located on the Ohio River.

The National Road was the very first highway built in the United States entirely through federal funds. Construction of the National Road was authorized in 1806 by Congress under President Thomas Jefferson. Congress wanted to establish a road from what was then the center of the United States in Maryland, to the westward side of the country at the time, which was Ohio.

The route of the National Road followed the path of the previous military road known as the Braddock Road, one that was carved out by George Washington and General Braddock in 1754-55. Unlike a lot of the early roads, the National Road was built to last from the start because this roadpath was paved with broken stones.

Today, the National Road is part of US Route 40.
