Williamsville Bridge - December 17, 2009
WGN 45-13-05

We picked the first truss to vertical today and installed the floor beams. More pics to follow. The process went without a hitch. We closed the road after the morning school bus run and reopened it for their afternoon run - but the pm buses never showed up? The road was open to full traffic an hour earlier than the Town of Newfane had asked for.

There was no dead load deflection from the flat built to vertical, in fact we shimmed our midpoint blocking a quarter inch or so for a tight seat. We'll pull the shim tomorrow and let it relax.

Next step is install trunnels from the outside in, which we couldn't do when the truss was flat. At the same time we'll install lower diagonal bracing, add a temporary working deck, cover ourselves up for the winter and build the 2nd truss on the flat on top of the temp deck

A big thank you to Mother Nature for only barking at us twice in the last month :-) But the first one had a little bite to it too...

I'm very proud of our work, so is the very select nitpickky crew I have working for me. They bite each other at night after work on just who did the best job today. And tomorrow's another day. Gotta tell ya, it was a nice feeling to see all the guys at the end of the day stand back in awe and look at what they had accomplished in the last month!

There was no dead load deflection from the flat built to vertical (the truss kept its built-in camber).

The second truss will be built atop a temporary deck on these floor beams.

What was and what is today - from flat to vertical and all the floor beams installed too :-)
