Minimize environmental impact, improve safety, and reduce long-term maintenance costs as you build and maintain the vital transportation systems that move people and goods.

RWDI’s decades of experience in snow drift, fog, air quality and noise, all backed by our reliable modeling work and extensive monitoring capabilities, gives you the peace of mind to plan, design, and manage safe road systems. We work with governments and municipalities to set the guidelines on how noise, air-quality, and greenhouse gases are assessed to keep our communities healthy.
