The Interstate Highway standards for the U.S. Interstate Highway System uses a 12-foot standard for lane width.
width of car door
on average about 6 feet.
An "average" traffic lane is 11-12 feet wide, so an "average" 4 lane street would be 44-48 feet wide. I have found most cities to differ in this, so it's almost impossible to find an "average"
The average dimension for the width of a car seems to come in at 6'. I measured several cars and mini vans and that was what I came up with. I also found an ad for the Nissan X TRA (an SUV) that said it was about the size of an average car and the width they gave as average was 6'. I found a math question at http://www.learnersonline.com/weekly/archive2K/week11/index.htm which gave the average car width at 6'.

The average width of a rural two-lane road is typically between 20 to 24 feet. This width allows for two lanes of traffic, one in each direction, with enough room for vehicles to safely pass each other.
The average width of a road lane originates from a combination of safety standards, historical practices, and engineering guidelines. It is typically determined based on factors such as traffic volume, vehicle size, speed limits, and available space for roadway design. Standard lane width in the US is 12 feet, but can vary depending on the specific context or jurisdiction.
The set standard lane width for dual carriageways and motorways is 3.65 metres. The set standard width for hard shoulders is 3.3 metres.
