Dearborn River High Bridge
Posted December 19, 2017, by Nathan Holth (webmaster [at] historicbridges [dot] org)

Yet another UNIQUE RARE HIGHLY SIGNIFICANT historic truss bridge damaged by a idiot truck driver (35 ton truck over 7 ton bridge) who again proves that some humans have significantly less intelligence than an earthworm with its brain removed... with earthworms, the brain is important for movement: if the brain of the earthworm is removed, the earthworm will move continuously... much like a truck driver ignorant of weight limit signs.
