The purpose of the Willits Bypass Project is to improve interregional traffic. An important benefit of removing traffic currently passing through the City of Willits on Route 101 will be improved air quality for the children attending schools and playing at parks located near the existing highway. In particular, diesel truck exhaust is known to have an effect on health, and diesel trucks produce even higher levels of emissions in stop and go traffic. Because children’s lungs are still developing, they are at a greater risk for developing health problems related to diesel exhaust than are adults. Relocating interregional traffic around Willits and allowing it to travel at a constant speed will reduce emissions from cars and trucks and improve air quality for all citizens of the Little Lake Valley.
