I found the bridge interesting because its a rare bridge designed by Turner. Although he invented the Turner truss, his real accomplishment was the development of the reinforced concrete slab in lieu of t-beams and such. I noted on this bridge the unusually wide cantilevered deck beyond the arch ribs, and I suspect this may be because Turner would have been comfortable doing strange things with reinforced concrete.
