Minimum lane width: The minimum lane width is 12 feet (3.7 m), identical to most US and state highways. Shoulder width: The minimum width of the left paved shoulder is 4 feet (1.2 m), and of the right paved shoulder 10 feet (3.0 m). With three or more lanes in each direction, both shoulders are to be at least 10 feet (3.0 m) wide.
In the United States, the Interstate Highway standards for the Interstate Highway System use a 12 ft (3.7 m) standard lane width, while narrower lanes are used on lower classification roads. In Europe, laws and road widths vary by country; the minimum widths of lanes are generally between 2.5 to 3.25 m (8.2 to 10.7 ft). [ 13 ]
The selection of lane width affects the safety, maximum capacity, and cost, of a highway. Safety is best at a width of 3.0 to 3.1 metres (9.8 to 10.2 ft) in urban settings, where both narrow (less than 2.8 metres (9 ft 2 in)) and wide (over 3.1 metres (10 ft)) lanes have higher crash risks.

This is a list of countries (or regions) by total road network size, both paved and unpaved.Also included is additional data on road network density and the length of each country or region's controlled-access highway network (also known as a motorway, expressway, freeway, etc.), designed for high vehicular traffic.
Eastbound at Mannheim Road (exit 17), the highway splits into two express and one local lane; they are joined by two onramps from I-88 and form express lanes three lanes wide and local lanes to Mannheim Road two lanes wide. After Mannheim Road, the highway immediately narrows to three lanes in width, causing mile-long (1.6 km) backups.
