From the Monument:
The concrete arch bridge before you was designed by the
Washington Water Power Co. in 1929. Grant Smith and
Company of Spokane finished construction of the bridge
the following year at a total cost of $22,948.00.
The bridge replaced a wooden structure which provided
both railroad and motor vehicle access to the island
during the construction of the dam and powerhouse.
Contrasting its graceful arch design against the
ruggedness of the river's gorge, the bridge is not only
beautiful but also functional and durable. It continues
to serve as the only access to the island for the
maintenance and operation of the Post Falls
Hydroelectric Development.
