Worrall Bridge Renovation-November 25, 2009
WGN 45-13-10
Hi! Exciting to see the crew working on the Worrall bridge today. Met some of the crew and as I had my safety gear on was invited on to the bridge.
There appears to be a leak in the roof about 10 feet in from the west portal and about a foot out from the lattice. I enclose a picture of a good sized puddle from a light mist and rain today. The roof was supposed to be ok?
The decking has been cut up and they were in the process or removing that and the floor beams. Interesting OSHA approved halters and safety winches that they were using.
Wood should be arriving in about two months. The construction crew thought that it would take until then to set the bridge up and do the dismantling needed. Wood is being taken to a special site or processing area as it contains creosote.
The cribbing to hold the ibeam scaffolding up is temporary and they plan to support the structure from the footings with 12" ibeams. The bridge is self supporting right now.
I will try to stop by at least once a week.
