Mountains to Sound Greenway
|
Across America, many interstate highways are the province of strip malls, billboards and spreading urban development. But people in the Pacific Northwest wanted a different future for the road over Snoqualmie Pass. In 1990, they created a plan for the Mountains to Sound Greenway to keep an accessible landscape of forests, wildlife habitat and open spaces as breathing room for people, and a place of incomparable beauty, history and outdoor recreation for their children and grandchildren. The Greenway stretches along 100 miles of Interstate 90 in Washington State from the waterfront in Seattle to the edge of desert grasslands in Central Washington. Today, most of the landscape not already developed along I-90 is in public ownership and protected as the Mountains to Sound Greenway and designated as a National Scenic Byway. The Greenway includes historic towns and over 750,000 acres of foothills, working farms and forests, spectacular alpine scenery, wildlife habitat, campgrounds, trails, lakes and rivers right in our backyard. The Mountains to Sound Greenway Trust is the nonprofit organization that helped to protect these lands and preserve them for the public's benefit. We carry that work forward by encouraging public land acquisition along I-90 and through environmental stewardship and educational activities. We unite hikers, corporate executives, government leaders, environmentalists and community advocates who share a vision of careful planning for growth balanced by preservation of forested open spaces, clean air and water, for ourselves and for future generations. |
