Friday, March 23, 2001 Wednesday, February 21, 2001 Fitches Bridge - a description
Thursday, December 20, Delhi, N.Y. - Hi Joe, I made the Fitch's opening ceremony-- very small and informal. I would say there were around 20 people including the Town Supervisor, Phil and Wayne Reynolds. It was very cold with a wind that cut right through you .
A Red ribbon was stretched across the portal and after several remarks, four people cut the ribbon at the same time.
The new bridge looks really nice, but it does not look like Fitch's bridge. I am glad I went, even though it was a long trip. Dick Wilson

Delhi, NY - Fitches Bridge Restoration Nears Completion.
Thursday, Nov. 1, 2001 - Hi Everyone! I thought you might enjoy seeing some new
photos on the progress made on the Fitches Covered Bridge - NY-13-02. These were taken on
Delhi, NY - Fitches Bridge Restoration Underway.
Thursday, 13 Sep 2001 - The Bridge Stands on its Own
Sunday, 10 Jun 2001 - Hi Joe - thought it was time for a brief update on Fitch's
I have attached three photos that offer a representation of our status. The first depicts the removal of the corners of the existing abutments to accommodate the slightly longer trusses when rebuilt (recall that we are restoring the trusses to their original length and eliminating the significant weakness introduced by their shortening in the way it was done).
The second photo shows a fascinating home chewed out of a pair of top chord members in a way such we did not know it existed until we removed the outside stick to replace an inside stick for other reasons. We're not sure just what critter made this home, but it was extensive and effectively removed the entire pair of chord sticks from any assistance with supporting axial compression in the bridge. The redundant nature of the Town Lattice bridge was a saving grace to enable the bridge to remain standing.
The third photo shows the flared arrangement of the bottom chords when the bridge was moved to this site and the results of some pretty bad rot. The flaring will be replaced with conventional parallel lattice members to the end of the rehabilitated structure. Note also that the older work caused the truss to be supported by both upper and lower bottom chords over a short length.
We have identified the lattice members that have to be replaced due primarily to deterioration
in the lower bottom chord connections (I have just taken a bunch of photos of these conditions
and will forward on later). Due to the surprise with the critter home in the top chord, we will
separate all of the top chord pairs looking for other surprises.
Monday, 11 Jun 2001 - Joe - three more photos to add to the last.
This photo of the abutment work is a better overall shot of work at one end of the bridge with the two corners formed for new concrete.
This close-up of a section of bottom chord lattice shows some of the deterioration we found behind the chords. This was obviously hidden from view at first. It also clearly depicts the problems with lattice connections at times - these holes can't do their job.
This side view from Route18 provides a view of the trusses supported by the falsework with work platforms in place. The trusses are nearly stripped of all bad material, with the exception of some of the lattice members that are still in place.
As of today, the guys installed the first new members in the old truss. The rebuilding is now underway. Phil

Fitches Bridge, Delhi, NY - So we're off and running with the rehabilitation of the
Covered Bridge. We have removed a couple of patches of the roof and floor to allow the
placement of steel piles down through the structure to help support an internal steel support
frame. Two main beams have been installed in the "belly" of the bridge and rest on columns in the
approach embankment at each end of the bridge and on the center pile "bent". (I was unwilling to
have us buy two extremely heavy and long steel beams in an attempt to avoid the center bent -
that would have been very expensive just for this purpose - the "two-span" temporary structure
serves just as well and used scrap material that we already owned.) The main beams are connected
with bracing and cables for stability. They support a pair of transverse steel box beams (old
pieces of box beam guide railing) at about 12 foot spacing.

From those top pairs of box beams we suspend two more pairs of transverse longer box beams (in this case, I term them "needle beams") that pass through openings in the lattice members of the trusses. These needle beams will support longitudinal walkways as work platforms inside and outside of the trusses and column supports to hold up the timber trusses while we work on them.
So far, we have the upper needle beams in place so we have had to remove most of the siding, yet the roof and most of the floor remains in place.

I am now following my design responsibilities with service as the "construction engineer" to help devise the means to hold up the old trusses while we work on them as well as the important temporary supports. However, the exact sequence of what is done next has some leeway. Hence, I am not sure what our guys will tackle next. But in some order, the next few weeks will include installing the new walkways and supports and the removal of the roof and floor of the bridge exposing the trusses for work. The timber has been ordered and should be here at the end of March.
So ends this portion of our new saga! Regards, Phil

Platform for BDI testing →
I am working on an article to be published about that, but in a nutshell, we did hire a firm to install a lot of strain gauges connected to a computer and recorded strains in the bridge while a truck drove through the bridge. Fascinating results and am trying to entice VAOT to consider similar work aimed at research.
The second pair of photos relate to getting started. The first from outside on the Route 10 side show (if you look close enough) the new center steel bent piling and the big beams hanging out the ends of the bridge. The second inside shows the pair of big beams with the steel rods suspended down through holes in the timber deck. Phil

Fitches Bridge, a Town Truss span of 100 feet, crosses the West Branch of the Delaware River. It was built in 1870 by James Frazier and James Warren three miles downstream from its present location. It was moved in 1885 to where it can be reached off NY Route 10 at East Delhi. World Guide Number 32-13- 02
