Description 

The first bridge to carry Mission Avenue traffic across the Spokane was swept away by the great flood of 1894 and was not soon replaced. Rebuilding the Mission Avenue crossing vs building a new bridge for Olive Street was the subject of heated civic debate which the city council finally resolved in favor of the Olive Street proposal in 1897. The Mission Avenue case was shelved for over decade. A resolution directing the city engineer, J.C.Ralston, to prepare plans for a reinforced concrete bridge at Mission Avenue was passed by the council on July 15, 1908. The authorized budget was $116,000.

Ralston produced plans for a five arch closed spandrel concrete bridge with a length in excess of 300 feet. Construction of the bridge was completed in the spring of 1909. The final expenditure for the project was $104,580 nearly $12,000 under budget
