Interstate 280 North - Santa Clara County


Interstate 280 (Sinclair Freeway) north
The first reassurance shield for Interstate 280 north appears after the off-ramp to U.S. 101 north and south, which marks the southern terminus of Interstate 680. For the next several miles, Interstate 280 will travel due west despite being labeled as "north." The Sinclair Freeway is named in honor of Joseph Sinclair, who was in charge of California State Division of Highways (now Caltrans) District 4 from 1959 to 1964. Sinclair was involved in the development of the freeway that now bears his name, and the Sinclair Freeway was added into the Interstate Highway System in 1962.1 Photo taken 11/29/04.
If not for the loop ramp connecting Interstate 280 south with U.S. 101 north, this interchange would be a symmetrical stack. Interstate 280 begins in the city of San Jose, home to 894,943 people as of the 2000 Census. Founded on November 29, 1777, and incorporated on March 27, 1850, San Jose is the third largest city in California (behind Los Angeles and San Diego). San Jose consists of 178.2 square miles and sits at an elevation of 85 feet. Rainfall in San Jose is much less than San Francisco due to its location at the south end of the San Francisco Bay and enclosure within mountains. The average annual precipitation is 14.4 inches.
