Interstate 680, North-south highway in Santa Clara and Alameda Counties, United States
Interstate 680 stretches through Silicon Valley and East Bay regions, connecting San Jose with numerous communities through valleys and mountain passes.
The highway started as State Route 21 in 1933 before receiving Interstate designation in 1955, marking a major transportation development for Northern California.
The route serves as a vital connector between Silicon Valley technology centers and residential communities, supporting the region's economic growth.
Travelers can access multiple interchanges linking to other major highways, including connections to Interstate 880, California 237, and US Route 101.
A large American flag mural appeared on the Sunol Grade concrete hillside after September 11, 2001, remaining visible to motorists until 2010.
