   A heated sidewalk in Holland, Michigan Installation of a geothermal snowmelt system on a street in Reykjavík, Iceland.. A snowmelt system prevents the build-up of snow and ice on cycleways, walkways, patios and roadways, or more economically, only a portion of the area such as a pair of 2-foot (0.61 m)-wide tire tracks on a driveway or a 3-foot (0.91 m) center portion of a sidewalk, etc.
