In this aspect, many people do not know the differences between highways and dual carriageways, so in this article we will show the more specific differences that exist between them, based on their brief definitions.
To begin with, a highway is a land communication route that connects different populations, which has been specifically designed and built for the exclusive circulation of motor vehicles at a constant speed. The highways do not cross urban sectors and have separate lanes for both directions, as well as independent entrances and exits located at intersections, junctions or distributors.
Even the highways lack crosswalks or pedestrian crossings as well as direct access to adjoining properties. In the same way, motorways do not have railroad crossings, tramways, footpaths or street crossings and they have the peculiarity of being prohibited from parking on them, except in cases in which some mechanical failure of the car forces you to stop on the right side. that consists of a paved path called shoulder.
Finally, the directions of the highways are mostly separated by a sector of land not intended for circulation or by some paved sectors in exceptional cases.
Basically, a highway is a land communication route that connects different urban populations and may lack land or land separating its two directions. However, initially these were conventional roads or streets that were later reformed and expanded according to the guidelines that characterize highways. That is why highways do not cross paths or railway or tram tracks and in the same way these roads do not cross highways at any level.
Thus, the highways lack crosswalks or pedestrian crossings as well as direct access to adjoining properties and consist of roads for each direction of traffic and are mostly separated by a road not intended for traffic. However, in some cases, they are separated by properties or land.
Additionally, highways have partial access control, that is, entrances and exits can occur at other points and not only through traffic links or distributors. Said entries and exits will be made through lanes specially designed for such purposes. Finally, given that highways cross urban sections, speed must be reduced in those sectors. For this reason, the speed of highways is usually variable.
As can be seen, there are several differences between highways and dual carriageways, which are summarized below:
|They do not cross urban sectors.||They may or may not cross urban sectors.|
|Both directions are separated by a sector of land not intended for circulation.||Both directions are separated by a paved road not intended for circulation or by a sector of land.|
|They do not have partial access control.||They have partial access control.|
|The speed of highways is usually constant.||The speed of highways is usually variable.|
