 Officials from the Iowa DOT and NDOR agreed that once a new bridge between Bellevue and Plattsmouth was built, the US 34 designation would be pulled from the Plattsmouth Bridge and applied to the new bridge.Construction of the new bridge began in 2010.While earthwork farther inland could take place, no work at the river could take place between February and June because the crossing was located in the spawning zone of the rare pallid sturgeon.
