Our next mystery bridge takes us back to Marion County, Iowa and precisely to this bridge. Located on the north side of Red Rock Lake just east of Hwy. 14, one finds this unique structure. From a bird’s eye perspective, the bridge is low enough that it may be considered a pontoon bridge. But it does seem weird that the roadway is low enough that it is on the same level as the water level of Red Rock Lake, making it prone to flooding. Yet looks can be deceiving. Have a look at the following pictures of the bridge when up close….
Judging by these angles, one can see that the bridge and road have not been used for a long time. These are the remnants of the old Hwy. 14 Bridge and highway, all of which are either partially or completely inundated by the waters of Red Rock Lake.
Here are some facts we do know about these remains. There were at least two bridges that carried the old highway (but guesses are three or four): this one and the Des Moines River crossing. Both of which were built in the 1940s replacing earlier structures that were most likely steel truss bridges. But this happened before plans for Red Rock Lake were revealed in the 1950s, sentencing this highway and the bridges, together with a dozen other bridges and at least six towns located along the Des Moines River to be inundated. While the removal and relocation of some structures in the area were successful, other streets and some places like this one were left to be covered in water. The new Highway 14 Bridge was opened in 1965 and featured three bridges, the longest one is over a mile long, making it the longest bridge in the state. Once the bridges were opened and the Red Rock Dam, located 10 miles east of there was completed, all of the obsolete Hwy. 14 and its bridges were left to be taken over by water. Today, once can access this bridge and the highway remains on the north end by foot only as well as fish from the bridge- a piece of history to be reminded of what the region looked like before Red Rock Lake was created.
What is missing about this bridge and old highway is the history: namely what the bridges and road looked like before they were inundated. Furthermore, information is needed about their construction history and the truss bridges that existed prior to their replacement in the 1940s. Photos and any information are welcomed.
