Introduction of Double Lane Bridge

Double Lane Bridge refers to a lane composed of two lanes in opposite directions (a lane is a belt-shaped section of a highway for a variety of vehicles to be arranged longitudinally and drive safely and comfortably). Double Lane Bridge include two-way four-lane, two-way six-lane, two-way eight-lane, of which two-way eight-lane is the most common.

In some cities, due to road reconstruction and expansion, the former two-way lanes have been changed to one-way roads to increase the capacity of the roads for co-vehicles and transportation.

In my country, the secondary and tertiary roads basically adopt two-lane roads. For the secondary roads in the plains and hilly areas, when the mixed traffic volume is large and it is difficult to separate the slow lanes, the lanes can be divided into fast and slow lanes. , But still a two-lane.
