Pearman Superstructure Preparation
As roadway is removed from the Pearman bridge that spans Town Creek,
there is less downward stress on the supports. Consequently, the
support might have a tendancy to rise vertically, placing a significant
new stress on the pins that tie the steel superstructure to the supporting
concrete structure.
Here is the end of the Pearman over Drum Island -
and work platform
for securing the end of the Pearman superstructure
A closer view of the work
On the left you can see a pair of vertical channels with two horizontal angle
iron brackets. On the right, the guys are preparing to add the two
horizontal angle iron brackets
Preparing to weld (with your curious eyes, you can see the welding rod in
his right hand)
About 30 min later - last weld on the top bracket
Cleaning the weld - but the big question for me is what is the purpose of
this addition?
