Road construction and usage can serve as a significant source of mortality for wildlife. [5] [6] Roads can affect animal movements either by acting as a barrier or allowing easier movement. [7] [6] [8] [9] Habitat fragmentation caused by road expansion can impact the movement and migration of species, as well as breeding and genetic structure.

Road construction requires the creation of an engineered continuous right-of-way or roadbed, overcoming geographic obstacles and having grades low enough to permit vehicle or foot travel, [38]: 15 and ...
A two-lane bypass road is currently under construction around the city of Rivne. The first phase is a built-from-scratch 6 km road section linking the N-25 and T-18-32 highways. The project aims to relieve heavy transit traffic in the city centre [24] and includes a 280-metre-long overpass above a ravine. [25]
Roads also may be classified based on their pavement material types. For instance, the Long-Term Pavement Performance database includes more than 30 types of pavement types for roads in the US and Canada. [2] [4] [5] However, a more generic classification of roads based on material type is as follows. [5] [6] Concrete roads; Asphalt roads ...

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 ...
E: These are main roads which go through multiple villages and small towns and are built similarly to B roads. A few of them can also be 4 lane dual-carriageways. F: The small village roads which normally only serve 1 or a few villages. These can be 2 lane roads but also a few of them are 1 lane but wide enough for 2 cars to pass
