Historic Covered Bridge
Committee Notes from meeting of November 10, 2005 for:
WILLIAM5VILLE COVERED BRIDGE (NO.
17), NEWFANE BHF 0106(4)5
Committee
members in attendance: Mike Hedges, Pam Thurber, Warren Tripp, Bob McCullough, Eric
Gilbertson, Nancy Boone, Scott Newman and Sue Scribner. Project Manager Roger Whitcomb
and
John Weaver were also in attendance as was Neil Daniels representing the Vermont Covered
Bridge
Society and Gary Katz and Henrik Van Loon from the Town of Newfane
This meeting
was a follow-up to previous meetings to discuss the latest
two proposals
under consideration. They are as follows:
1. Rebuild the covered bridge
using all new timber but same dimension/design as the existing
covered bridge.
2. Sister all of the
existing lattice members (all of which have the ends cut off) by superimposing new
sister members directly over the existing lattice members as well as adding an additional layer to
the upper and lower bottom chords.
Both
scenarios were presented by project manager Roger Whitcomb with the clarification that glulam
deck panels are suggested. Sacrificial full width running planks were also suggested. It was
clarified
that the rehabilitation will likely take a full construction season and that a temporary bridge will be
necessary.
It was stated
that there is a lot of rot in the south side of the bridge along with a lot of bolt holes. It was
questioned whether or not the 2nd proposal would be a long term fix for the
bridge. This then led to
questions as to whether or not the bridge would need to be disassembled. Also it was asked if the
glulam beams currently in place and supporting the bridge could be somehow moved in to support
the
bridge while any rehabilitation work was being done. Both Warren Tripp and Neil Daniels did not
feel that
this was
feasible. There was
considerable discussion as to predicting how much of the original fabric could be
saved from the original bridge, particularly in the upper chord as there is rot evident and new
members
bolted in. While not fully known until work begins, there were opinions expressed that the upper
chords should
not be touched unless absolutely necessary. It was also suggested that the roof be extended to
offer
protection to the trusses although some questioned whether this would be of any value. The
Town
reported that the town voted in March, 2000 for a new 1-lane covered bridge, but as long as a covered
bridge remained, they felt that the Newfane voters would be happy with either option.
After
additional discussion, a motion was made to vote to approve the rehabilitation option that
involves
sistering the lattice members and chords (Option 2). It was seconded and then amended to vote to
keep
the 1978 upper chord bolted members in place if possible. With the Town voting as well as the
permanent
committee members, there were 7 votes to approve, 1 in dissension and 1 abstaining vote. In
dissent,
Scott Newman stated that he did not feel that the limited amount of original fabric preserved in
this
rehabilitation warranted what he perceived to be substantial changes to the original design and
would
instead favor the reconstruction of the original design with such modifications required to meet
required
loading. However, with the vote taken, this will place the bridge in Category B of the Priority of
Uses and
the Priority of Treatment will be Number 3 per the Historic Covered Bridge Preservation Plan.
There was a
second motion made, seconded and amended to read that the project manager would be given the
option
of recommending for clearance by the VTrans Preservation Officer that the roofline of the bridge
be
extended if it seems warranted and beneficial after additional study. This was unanimously passed.
Respectfully submitted,
Susan
