Builders often use concrete for primary and secondary walkways. Primary walkways are the most frequently used, such as the main entry walk to a house. Walkways are widest for the most prominent locations. Secondary walkways are used less often and are narrower.
Walkways that are 4 1/2 to 5 feet wide are safe and convenient; two people can walk side by side. Secondary paths can narrow to 3 feet. This is suitable for infrequent use such as back yards and utilities.
Accessible walkways should be a minimum 6 feet wide; the preferred width is 6 1/2 feet. This permits wheelchairs to pass and allows for snow storage without blocking the way. Check local regulations for specifications for walkway widths, especially for accessibility issues.
