A modern Autobahn divided highway with two lanes per direction has lanes 3.75 m (12.3 ft) wide with an additional clearance of 0.50 m (20 in) on each side; with three lanes per direction this becomes 3.75 m (12.3 ft) for the rightmost lane and 3.5 m (11 ft) for the other lanes. Urban access roads and roads in low-density areas may have lanes as ...
In mountainous terrain, a left shoulder of 4 feet (1.2 m) and a right shoulder of 8 feet (2.4 m) are acceptable, except where there are at least four lanes in each direction, in which case both shoulders are to be at least 8 feet (2.4 m) wide. In places with higher truck traffic, over 250 directional design hour volume, wider shoulders should ...
A median strip, central reservation, roadway median, or traffic median is the reserved area that separates opposing lanes of traffic on divided roadways such as divided highways, dual carriageways, freeways, and motorways. The term also applies to divided roadways other than highways, including some major streets in urban or suburban areas.
Traffic on the minor road wishing to turn left or continue straight must turn right onto the major road, then, a short distance away, use a U-turn (or crossover) lane in the median before either going straight or making a right turn when they intersect the other half of the minor road. Super two, super two-lane highway, or wide two lane
Tolls: Express lanes use a “dynamically priced toll,” which means that the toll price shifts depending on how much traffic is on the road. The minimum toll is 50 cents at each toll point, and ...
In a lane diet, the width of a car lane is decreased to reduce vehicle speeds and accidents [3] and provide space for other use. [4] Typically vehicular travel lane widths are narrowed to no more than 2.8 metres (9.1 ft), [5] and left turn (in countries where cars travel on the right-hand side of the road) storage lanes between 2.7 and 3.0 metres (9 and 10 ft).

The Michigan Department of Transportation will review new traffic data and could alter some of what it has put forward for the I-375 replacement.
A wide outside through lane (WOTL) is a WOL that is intended for use by through traffic. Conversely, a narrow lane is a lane that is too narrow to be safely shared side by side by a bicycle and a motor vehicle. When the outside lane of a roadway is a narrow lane, it is sometimes referred as a narrow outside lane (NOL), narrow curb lane (NCL) or ...
