Sweetware River Bridge
This bridge was built in 1929 by Pacific Iron & Steel Co of Los Angeles. It is a three span, Parker Truss bridge - only 22 feet wide (virtually a one way bridge for large trucks) and 460 feet long.
It is one of the remaining three truss bridges and the only Parker Truss bridge in San Diego County. It is included in the National Register of Historic Places. It is the only bridge in San Diego County that used a type of construction, popular in the early 1900’s, in which the parts were bolted together before construction, then put into place by relatively unskilled labor.
It is unique because the upper members of the bridge form an arch rather than being straight.
