Slick layers of ice left behind by snow plowing, renewed demands for salt and sand use. No longer concerned about protests, city public works officials used salt by the ton to ease road conditions, and also experimented with cinders and sand. Motorized salt spreaders became the primary tool in fighting snowy roads, and businesses and private citizens as well used tons of salt to keep driveways, sidewalks and access routes clear of snow and ice. However, several cities in the Great Lakes region were unable to use salt due to the extremely frigid weather that rendered salt almost ineffective. In any city, while salt works well on icy roads or minimal snowfall, it does little good against deep snow.
Parked and abandoned vehicles posed the other great problem faced by snow removal crews. Urban streets now provided parking places, which in winter months hampered snowplowing efforts. Desperately needing to clear the streets, plows ended up packing huge, compacted drifts against parked cars, forcing unwary owners to dig them out. Realizing there was a conflict, city ordinances were created, banning overnight parking for certain city areas, or posting signs marking snow plow routes, where parking would be banned when plows were in use. Many of these ordinances are still in effect throughout major cities, increasing the efficiency and thoroughness of plowing efforts.
