Hi Bill,
OK – I’m officially confused…help me get my bearings…
Below I’ve mapped out a diagram as if you were looking at the bridge from the
south side. (I hope Yahoo doesn’t scramble it)
The G’s indicate where the plate girder spans are, the PP’s mark where the
existing piers are.
I’ve put an X where I envision where they are adding the new pier from your
description. Are they planning on shortening the length of the new lift span
from 302’ to 227’?

they have moved appox. 75 yds east and are building a complete new prier and
this will put the west pier in the middle of channel on the west side of the
draw span.They had to do this as they could not bore down to bedrock next to
the east prier because of the debris laying on the bottom of the river.no
construction has started yet on the new loift span
