Golden Gate bridge history. The Golden Gate Bridge is a suspension bridge spanning the Golden Gate, the opening of the San Francisco Bay into the Pacific Ocean. As part of both U.S. Route 101 and California State Route 1, the structure links the city of San Francisco, on the northern tip of the San Francisco Peninsula, to Marin County. It is one of the most internationally recognized symbols of San Francisco, California, and of the United States. It has been declared one of the modern Wonders of the World by the American Society of Civil Engineers. The . 1. Find the solution(s): 2. Solve and graph the inequalities: 3.
