The invention provides a road snowmelt system. The road snowmelt system is characterized in that a well floor is arranged in a road sewage well or a rainwater well, a drain pipe is communicated on theside wall of the well, a well lid is arranged at the position of the wellhead, a heat conducting plate is arranged above the well floor parallelly, the heat conducting plate and the well floor are fixedly connected through multiple uprights therebetween, multiple heat conducting rods are fixedly mounted on the heat conducting plate, other ends of the heat conducting rods extend below the wellheadand are fixedly connected with one ends of horizontal radiation rods laid under the floor, multiple longitudinal radiation rods are evenly arranged on the horizontal radiation rods at intervals, thehorizontal radiation rods and the longitudinal radiation rods intersect to form a net structure, and the heat conducting plate, the heat conducting rods, the horizontal radiation rods and the longitudinal radiation rods are heat conducting materials. By the arrangement, problems that road snow usually cannot be cleared timely in the prior art resulting in the fact that lots of inconvenience is brought to daily life are solved.
