Primary routes are our first priority for plowing and applying materials.
Primary routes are the major streets that run throughout the city. Two plow trucks are assigned to each of our five primary routes. Secondary routes are the streets around schools and hospitals, most RTD bus routes, collector streets and streets requiring special attention in snowy conditions. Plowing of these routes begins at the same time as plowing of primary routes, however, there is one truck assigned to each of these routes. To minimize environmental impact, the city uses alternative deicing and traction materials.
