The recommended width for a windrow on low to medium traffic streets being 4-8 feet is based on the need to effectively manage snow and ice removal while ensuring safety and accessibility. In winter operations, the goal of forming a windrow is to contain snow and ice in a way that allows for safer driving conditions. A windrow width of 4-8 feet balances the need to keep adequate space for vehicle passage while ensuring that enough salt can be effectively applied to melt ice and provide traction. This width allows for efficient use of materials and minimizes the potential for ice build-up, which can occur if the windrow is too narrow, or excess spreading on the road if it’s too wide.

Choosing this width helps to manage road conditions for average traffic volumes while also accommodating any potential needs for emergency access. It's important to recognize that the width must be suitable for the type of street and expected traffic, thus ensuring both safety and effective maintenance practices.
