A smart friend told me on the phone today that the Army Corps of Engineers can rebuild a bridge within 48 hours.
Did ya see the traffic in Medford Square this morning / afternoon with the bridge situation?
Moving a 122.5 m Arch bridge in 7 hours
Bridges are structures built to span physical obstacles, in order to
provide a direct passage throughout such obstacle. Some time ago the
U.S. navy faced the need to build a bridge in order to connect its
existing base in Manama - Bahrain with new expansion properties located
on the other side of the Sheikh Khalifa bin Salman Causeway. Initially
this seems an ordinary building task; however, an in situ building would
have meant to interrupt the causeway and nearby traffic for several
days. Thus, it was decided to build the bridge at other location and
then move it into place.
Initially the Army Corps planned to close the causeway some 48 hours in
order to allow enough time to prepare the road for the move by removing
the curb and median and then subsequently moving the bridge into place.
However, Bahrain authorities said that the closure time should be
limited to 7 hours.
In order to move the massive bridge, self propelled mobile transports were used. These machines, two twelve axle units on each corner, lifted the bridge at its bearing points and safely moved it onto pre-constructed abutments.
