The Scoville Bridge 

In the arid south west of the United States more than anywhere else, the growth of a city was dependent upon water. Pasadena was founded where it was exactly to take advantage of a reliable water supply, the Arroyo Seco ("Dry Gulch" in English). It was a reliable source of water in a rather dry environment.

However the Arroyo Seco was also problem, it was deep in a steep sided canyon. This meant that Pasadena was physically isolated from its western neighbors. Travelers would have to make long detours passable crossing north or south of Pasadena.

This was finally changed by James Scoville. He had been the Vice President of the Elgin Watch Co., President of the Prairie State Bank, and a trustee of what would later be known as California Institute of Technology. He built a pleasure garden on the bluff above the Arroyo Seco which went down the slope of the canyon walls to the stream itself. There he built a small dam and pump house. The top of the dam served as the eastern abutment of a wooden bridge, the first connect Pasadena to the western side of the Arroyo. Scoville Bridge was still in service when the much larger and grander Colorado Blvd. Bridge was built above it.
