Union Pacific replaces 110-year-old, 170-ft-long, double track bridge with a 203-ft-long double track bridge with a through plate girder span... in two days, in Denison Iowa over the East Boyer River
Multiple cranes, including a towering 650-ton crane, assisted in the demolition and heavy lifting. The new main span was slid over into place by heavy-duty jacks and rollers.
cool
ReplyDeletecan you imagine how long it would take the state to replace this exact same bridge on an interstate highway? five years at least.
