Concrete Walkway Average Costs. The cost of a concrete walkway is largely determined by the type of concrete poured. 1  A plain concrete walkway costs $4 to $6 per square foot. 2  Adding a single color or simple finish to the concrete raises the price to $6 to $10 per square foot. If itâs necessary to first remove existing concrete, costs will rise by approximately $2 to $6 per square foot (if hiring a pro; DIY removal is cheaper). 2  Although weâre accustomed to seeing concrete as the drab stuff of sidewalks, it actually has robust decorative potential.
