Plateau Transportation Facility

3402 228th Ave SE
Sammamish, WA 98075

The Plateau Transportation Facility on the Sammamish plateau was built to solve the issue of plateau-bound buses driving the miles to and from the main bus facility in downtown Issaquah each day rather than starting from and returning to a closer plateau location. Eliminating those few miles each day saves travel time and gas.
