they temporary bridge was quickly built by locals and volunteers in Northeastern Tennessee for crossing the river bed after the real bridge was destroyed during flooding from Hurricane Helene

three flatbed trailers placed parallel, because they are easy to install and remove, and the load rating of a semi trailer is a known quantity!

because locals still need supplies, whether it be food, building materials, or what have you, and when there’s only one way in and out of town, they have to do all they can to keep it open.

This is similar to using railroad car beds like I posted in years past
