How wide is a lane in a lane mile?

Answer 1

A typical lane width is considered to be 12ft but does vary depending on the type of road and the location as some municipalities may vary.

While the U.S. Department of Transportation maintains a breakdown of statistics for the lane widths of Interstate & arterial roads that deviate from the 12ft standard, most highway departments simply measure a Lane Mile as a single lane running for 5280ft, regardless of the width. Obviously if you are calculating to precise measurements, such as the number of square feet, you would either need to do some averaging, or have an extremely large supply of very rugged tape measures.

Answer 2

The width of traffic lanes vary between nine and fifteen feet. The interstate highway system's lanes are standardized at 12 feet.

Answer 3

A standard lane width in a lane mile is typically about 12 feet wide. This width allows for one standard-sized vehicle to safely occupy the lane without encroaching into adjacent lanes.

Answer 4
