What is the width of a two-lane road?
1 Answers
The width of a two-lane urban road is usually 6 or 7 meters. However, to save land, the lane width is often narrowed. The national standard stipulates the width of each motor vehicle lane on highways. For multi-lane highways above grade three, the width of each motor vehicle lane is 3.5~3.75 meters. Below is an introduction to China's regulations on lanes: 1. Standard lane width: A two-way four-lane road is 2*7.5 meters; a two-way six-lane road is 2*11.25 meters; a two-way eight-lane road is 2*15 meters. 2. The national standard specifies the width of each motor vehicle lane on highways. For multi-lane highways above grade three, the width of each motor vehicle lane is 3.5-3.75 meters. 3. Median strip: There is no unified standard for the central median strip, which is determined based on local conditions. A simple cement central median strip is one meter wide. If it is a central green median strip, there is no unified standard for the width. Some 'image project' roads can have a median strip width of several tens of meters.
