What is Road?

Legal Definition
A road is a thoroughfare, route, or way on land between two places that has been paved or otherwise improved to allow travel by foot or some form of conveyance, including a motor vehicle, cart, bicycle, or horse.

Roads consist of one or two roadways (British English: carriageways), each with one or more lanes and any associated sidewalks (British English: pavement) and road verges.

Roads that are available for use by the public may be referred to as parkways, avenues, freeways, interstates, highways, or primary, secondary, and tertiary local roads.

A passage through the country for the use of the people. 3 Yeates, 421.

2. Roads are public or private. Public roads are laid out by public author-ity, or dedicated by individuals to public use. The public have the use of such roads, but the owner of the land over which they are made and the owners of land bounded on the highway, have, prima facie, a fee in such highway, ad medium filum vice, subject to the easement in favor of the public. 1 Conn. 193; 11 Conn. 60; 2 John. 357 15 John. 447. But where the boundary excludes the highway, it is, of course, excluded. 11 Pick. 193. See 13 Mass. 259. The proprietor of the soil, is therefore entitled to all the fruits which grow by its side; 16 Mass. 366, 7; and to all the mineral wealth it contains. 1 Rolle, 392, 1. 5; 4 Day, R. 328; 1 Conn'. Rep, 103; 6 Mass. R. 454; 4 Mass, R. 427; 15 Johns. Rep. 447, 583; 2 Johns. R. 357; Com. Dig. Chimin, A 2; 6 Pet. 498; 1 Sumn. 21; 10 Pet. 25; 6 Pick. 57; 6 Mass. 454; 12 Wend. 98.

3. There are public roads, such as turnpikes and railroads, which are constructed by public authority, or by corporations. These are kept in good order by the respective companies to which they belong, and persons travelling on them, with animals and vehicles, are required to pay toll. In general these companies have only a right of passage over the land, which remains the property, subject to the easement, of the owner at the time the road was made or of his heirs or assigns.

4. Private roads are, such as are used for private individuals only, and are not wanted for the public generally. Sometimes roads of this kind are wanted for the accommodation of land otherwise enclosed and without access to public roads. The soil of such roads belongs to the owner of the land over which they are made.

5. Public roads are kept in repair at the public expense, and private roads by those who use them. Vide Domain; Way. 13 Mass. 256; 1 Sumn. Rep. 21; 2 Hill. Ab. c. 7; 1 Pick. R. 122; 2 Mass.
