What is the width of an 8-lane road in meters?
2 Answers
8-lane roads have a width of 2 times 15 meters. Below is relevant information: Introduction: The state has standards for the width of each traffic lane on highways. For multi-lane roads above level 3, each traffic lane is 3.5~3.75 meters wide. Additional information: Highways between towns generally don't have sidewalks, while urban arterial roads must include sidewalks. The width of sidewalks on urban arterial roads is calculated based on actual pedestrian flow, typically at least 3 meters wide, with wider ones reaching 15-20 meters. Taking a first-class highway with a 26-meter red line as an example: it has 18 meters for bidirectional six lanes, 1 meter for the central divider, 3 meters total for 1.5-meter shoulders on each side, and the remaining 2 meters on each side are allocated for drainage ditches and other supporting facilities.
I've been driving for most of my life and have driven on many eight-lane roads, which are generally between 28 to 30 meters wide. For example, the standard design on highways is about 3.5 meters per lane, totaling 28 meters for all lanes, not including shoulders and median barriers. When I drove on the Beijing-Shanghai Expressway, I measured the width to be just over 29 meters. Driving on such wide roads feels spacious, making overtaking much easier. I recall the narrow roads from my younger days, where accidents were frequent. Nowadays, roads are wider and safer. I advise new drivers to practice lane control, maintain safe distances, and avoid excessive speed.
