Unfortunately, sometimes people just look at the modernized railing and assume that they are looking at a replacement span. It's a shame that many of these arches have lost their original and sometimes very ornate railings.
As shown in photos, this bridge is still in place.
Was it replaced? If it is now "beam" then it may have, can anyone confirm?
I went to look at this bridge (6-17-2008) and found it to be a "Beam" bridge at this time. The Facts Design information list it as "Arch" on this site. That is no longer true.
