Context: Court Manor (built as Mooreland Hall) is an early Greek Revival plantation house and estate in Rockingham County, Virginia, located 4 mi south of the town of New Market.  With its stately manor house and prime location in the heart of the Shenandoah Valley, Court Manor has long been regarded as "one of the finest estates in the Valley of Virginia."  The estate is situated on U.S. Route 11, which follows the route of the historic Great Wagon Road, a colonial thoroughfare connecting Philadelphia, Pennsylvania to Savannah, Georgia.  The estate's landholdings include some 2000 acre of land, extending from the base of the Massanutten Mountain Ridge to about one-half mile (0.5 mi ) west of U.S. Route 11.  The manor house (circa 1800), with its impressive Greek Revival portico, can be easily seen from the tree-lined stretch of U.S. Route 11 that passes through the heart of the estate. Cooke's Wagon Road or Cooke's Road was the first wagon road between the Rio Grande and the Colorado River to San Diego, through the Mexican provinces of Nuevo México, Chihuahua, Sonora and Alta California, established by Philip St. George Cooke and the Mormon Battalion, from October 19, 1846 to January 29, 1847 during the Mexican American War.  It became the first of the wagon routes between New Mexico and California that with subsequent modifications before and during the California Gold Rush eventually became known as the Southern Trail or Southern Emigrant Trail. Wagon Mound is a village in Mora County, New Mexico, United States.  It is named after and located at the foot of a butte called Wagon Mound, which was a landmark for covered wagon trains and traders going up and down the Santa Fe Trail and is now Wagon Mound National Historic Landmark.  The shape of the mound is said to resemble a Conestoga wagon.  As of the 2000 census, the village population was 369.  It was also called Santa Clara for many years.  The village, with brightly painted houses and several stores and shops, is located on the plains of northeastern New Mexico.  Interstate 25, which skirts the west side of town, gives a view of the majority of the town.  Wagon Mound is not growing rapidly, but it has seen new construction along I-25, with new buildings on the northeast side of town as well. The Elliott Cutoff was a covered wagon road that branched off the Oregon Trail at the Malheur River where present-day Vale, Oregon, U.S. is today.  The first portion of the road was originally known as the Meek Cutoff after Stephen Meek, a former trapper who led over 1,000 emigrants into the Harney Basin in 1845.  There were considerable difficulties for the 1845 train and after reaching a hill known as Wagontire, the people left Meek and split into groups.  They turned north at the Deschutes River and finally returned to the traditional Oregon Trail near The Dalles, Oregon. Leaving of Pecos was originally a camping place along the west bank of the Pecos River, on the wagon road called the Lower Emigrant Road, Military Road or San Antonio-El Paso Road in Texas.  It was located 38 miles north of the Lancaster Crossing of the Pecos, and 16 miles east of the first crossing of Escondido Creek.  It was also located a mile north of where the wagon road had its junction with a cutoff to the north to the wagon road called the Upper Emigrant Road between Fredricksburg, Texas and Comanche Springs, now Fort Stockton, Texas, where it joined the Lower Emigrant Road.  It was later a stopping place on the route of San Antonio - El Paso Mail and the San Antonio-San Diego Mail Line. The covered wagon was long the dominant form of transport in pre-industrial America.  With roots in the heavy Conestoga wagon developed for the rough, undeveloped roads and paths of the colonial East, the covered wagon spread west with American migration.  Heavily relied upon along such travel routes as the Great Wagon Road and the Santa Fe and Oregon Trails, it carried settlers seeking land, gold, and new futures ever further west. The Carolina Road or the "Old Carolina Road" are names for various sections of the Great Wagon Road and other routes in colonial America.  "The 'Old Carolina Road', extending from Lancaster, Pennsylvania to the Yadkin Valley, was one of the most heavily traveled roads in eighteenth century America."  Parts of the 180 mile long Journey Through Hallowed Ground National Heritage Area scenic byway follows the Old Carolina Road through Pennsylvania, Maryland and Virginia. The Meek Cutoff was a covered wagon road that branched off the Oregon Trail in northeastern Oregon.  The road is named for frontiersman Stephen Meek, who was hired to lead the first wagon train along it in 1845.  The journey was a particularly hard one, and many of the pioneers lost their lives. The Great Wagon Road was an improved trail through the Great Appalachian Valley from Pennsylvania to North Carolina, and from there to Georgia in colonial America. The transport infrastructure of Greater Manchester is built up of numerous transport modes and forms an integral part of the structure of Greater Manchester and North West England – the most populated region outside of South East England which had approximately 301 million annual passenger journeys using either buses, planes, trains or trams in 2014.  Its position as a national city of commerce, education and cultural importance means the city has one of the largest and most thorough transport infrastructures which is heavily relied upon by its 2.7 million inhabitants in the Greater Manchester conurbation and further afield in the North West region.  Public transport comes under the jurisdiction of Transport for Greater Manchester.
