The date of the construction of the first viaduct on Peoria Street has been lost to time. The TP&W railroad was constructed through Washington in the 1850s. The original viaduct construction, as seen below, was over a dirt road and was not straight. It was made of stone and had no side rails on top.
Changes were needed with the invention of the automobile, so a new bridge was constructed for $10,000 in 1912. Except for the road below and various paint jobs, the 1912 viaduct looks the same today.
