SR 167, also known as the Valley Freeway, is an important highway for moving people and goods in the Puget Sound. It serves as an alternative to I-5, connecting south King and north Pierce counties to the cities of Seattle and Bellevue. Today’s drivers are experiencing traffic congestion up to six hours a day, affecting commerce and commuters. The largest freight distribution center in the Puget Sound Region is located along SR 167, and housing developments continue to increase. The population of the cities along the highway nearly doubled from 1970 to 2005. By the year 2030, at least 100,000 more people will probably be living along the corridor to take advantage of less expensive housing and available land.
