Instead of demolishing it and building new, repurposing the original structure provided environmental benefits to the local community including less pollution and disturbance of the site. Site improvements included underground utilities, below-grade Chambermaxx® systems, a swimming pool, jointed plain concrete pavement, and pervious concrete.
Then a single bridge carrying two-way traffic, the structure was expanded in 1958 when a second twin bridge was built directly adjacent to the original structure. With the twin bridge structure, each bridge was opened to one-way traffic–northbound traffic being run over the 1917 structure and southbound over the 1958 structure.
