Hopkinton, NH Bridge Collapse, Nov 1993

TWO DIE IN COLLAPSE OF BRIDGE.

Hopkinton, N.H. (AP) - A temporary bridge collapsed onto a New Hampshire highway Wednesday, killing two workers but missing traffic below.
The single-lane temporary bridge, about 90 to 100 feet long, was built to carry traffic while an adjacent highway bridge was resurfaced this summer, said Leon Kenison, chief New Hampshire state highway engineer.
The permanent bridge, about 10 miles northwest of Concord, was reopened about three weeks ago. The temporary bridge's deck was removed Tuesday and four workers were taking down steel beams Wednesday, Kenison said.
"They had removed some ... but the last one they removed caused the whole configuration to go unstable, and over it went," Kenison said.
The structure fell about 20 feet onto a busy local road.
"There is an awful lot of traffic," on Sugar Hill Road below the span in West Hopkinton, said Police Chief Ira Migdal.
The injured man and a fourth worker who was not harmed both jumped clear as the structure fell, police said.
