Maybe they wanted a bridge with higher elevation in case the lake filled up during high water events. Its also worth noting that the new bridge was a realignment for the highway too so it may have afforded a better curve for the highway. It was not unheard of for bridges in this period of rapid development of highways to have a short service life as highways were realigned to allow for safer and higher speeds.
