π‘ Nebraska bridge heats itself to fight snow βοΈ
A Nebraska bridge is now using special concrete to melt snow and ice instead of relying on salt. The 150-foot Roca Spur Bridge, located near Lincoln, first used conductive concrete in 2002. It features 52 conductive concrete slabs, with testing shown in December 2015. This system cuts down on chemical use and can be cheaper to operate than traditional de-icing. Researchers plan to use this technology only where ice problems are frequent.
