safe_image for Iconic Idaho bridge on National Register of Historic Places faces DEMOLITION
ITD (Idaho Transportation Department) plans to replace this bridge. "'Rainbow Bridge, the largest single-span concrete arch structure in Idaho, remains today as a major achievement. [It] not only reflects the leading edge of bridge engineering of its time, but also exemplifies a conscious effort to meld a modern structure with a picturesque natural setting,' the National Register of Historic Places said in 1999." "While the bridge would not be safe for traffic or pedestrians again, the ITD has proposed scenarios in which the bridge could be preserved." |
The second quote above does not make sense to me. First of all, how can a bridge that is currently carrying traffic not be safe for pedestrian use? Secondly, why would you spend money to preserve a bridge if pedestrians can't use it? I got this closeup street view to confirm that there were no weight restriction signs. Every car I know of weights a lot more than any person I know of. If the bridge could hold multiple cars in 2024, why can't it hold pedestrians as is?
Here are three of the nine proposed designs from ITD via
DailyMail.
