Transportation systems that put cars front and centre cause a lot of damage, we know this. But aspects of our cultural approach to getting around like, the reliance on road salt, are easily ignored. Every winter in North America we dump an unfathomable amount of salt on our roads which subsequently kills off wildlife. The costs of using road salt are high.
Cities are waking up to the damage years of salting their roads have done not only to local ecosystems but also to their budgets. Using road salt isn’t cheap and now cities are looking to alternatives, or at the very least, strategies to reduce the amount of salt they put on roads.
Area officials found that, pound for pound, brine was far more efficient than traditional rock salt. They could protect a lane-mile of road with a solution containing under 100 pounds of salt, roughly one third the amount used by rock-salt trucks.
Last, the towns switched to live-edge plows, which have flexible blades made up of multiple, independently moving sections mounted on springs. These state-of-the-art blades are more thorough than conventional ones. And starting with brine makes the plows even more efficient, says Eric Siy, executive director of The FUND for Lake George. If live-edge snowplows are like razors that hug the curves, brine is like shaving cream.
