The width of a single travel lane can vary from 10'-12'. The faster the traffic is intended to travel, the wider the lane needs to be. Therefore, city streets with a speed limit of 25-30 mph should have 10' lanes, while highways should have 12' lanes. In addition, you may have a median, a shoulder, a bike lane, or a parking lane that would increase the road width.
