The minimum clear width for single wheelchair passage shall be 32 inches (815 mm) at a point for a maximum length of 24 inches and 36 inches (915 mm) continuously.
In U.S. English, the word sidewalk refers to a paved footpath alongside a street or a road. The sidewalk is usually raised above the level of the road. The curb is a stone or concrete edging between the road and the sidewalk.
While site constraints often determine the width of your front walkway, ideally a front path should be no less than 4 feet wide at its narrowest and no wider than 6 feet. At 4 feet, two people can walk abreast.

Do Sidewalks Need Rebar? Most sidewalks don't need to be reinforced with rebar. Rebar is a steel bar used to reinforce the strength of concrete used to withstand heavy weight. General use sidewalks don't benefit from the addition of rebar.
How strong is 2 inches of concrete? A common bag of concrete, for example, may have a compression strength of 4,000 psi, based on a thickness of 2 inches after it has set for 28 days. Other concrete may have a compression strength of only 550 psi.
Whether you pour concrete for a walkway or patio, a strong gravel base is required to prevent the concrete from cracking and shifting. Gravel is especially important in clay soil because it doesn't drain well, which results in water pooling under the concrete slab and slowly eroding the soil as it finally drains.
QUIKRETE® Concrete Mix is a good general-purpose mix for sidewalk and slab work. Sidewalks should be at least 4″ in thickness. Simple slabs for small foundations, bases, etc., normally 4″ to 6″ thick, depending on the load they must bear. Slope the walk away from buildings to provide proper drainage.
No, you do not need rebar for a 4-inch slab of concrete on grade. A 4-inch-thick slab cast on the ground and in permanent contact with it will float and rebar is not required. Rebar is recommended on concrete measuring 5 – 6 inches thick.
How to calculate concrete:
- Determine how thick you want the concrete.
- Measure the length and width that you'd like to cover.
- Multiply the length by the width to determine square footage.
- Convert the thickness from inches to feet.
- Multiply the thickness in feet by the square footage to determine cubic feet.
On average, it will take 90 40lb bags, 60 60lb bags, or 45 80lb bags to fill one cubic yard of concrete.
When it comes to concrete, you can't avoid cracks entirely, but wire mesh reinforcement will help hold the material together when they do occur. Also, it will help evenly distribute the weight of cars on your driveway. The added strength of steel is especially crucial if your subgrade isn't up to par.
