2. Outline of presentation
I don’t like outlines, but…
A CB project often requires it to be relocated
Construction of new or replacement structure
Rehabilitation of existing structure
Various means of relocating a CB:
Transverse slide
Longitudinal slide
Lift with crane(s)

3. Bartonsville Replacement
Recent example located in the Town of Rockingham, along the east edge of Vermont about 30 minutes north of the Massachusetts line
Original bridge built 1870–one of the longest single-span CBs in the USA
Supported by Town lattice trusses

5. Background August 28, 2011 Who remembers what was going on?
(for those of you NOT from the Northeast, it was a little thing called Hurricane Irene)

6. Perhaps one of the more “popular” YouTube videos of that event (taken by Susan Hammond)

8. Construction and Erection
<= Piles driven to rock – these abutments are going to stay!
A shelf extension to help a bit with waterway opening =>
<= Getting ready to install the temporary bridge for traffic during construction

9. Construction and Erection
Temporary Mabey Bridge for traffic maintenance
First timber truss built flat on the work platform bridge
Work platform bridge being erected

10. Construction and Erection

11. Moving into position
<= nearing completion of the new bridge atop the work platform bridge, while traffic still on the Mabey Bridge
Mabey Bridge out, making ready to shift the new one sideways onto the abutments =>

12. Moving into position
Underside at end – lifted the timber bridge (with the bolster beams strapped in place) – then installed metal frame with rollers =>
<= “Hilman rollers” inside belly-up channel

13. Moving into position TIME OUT!!!! <= Here he comes – watch out!
I’m baaaccckkkk! =>

14. Moving into position
<= 10-ton come-along to pull the bridge sideways – none of us dreamed it would be this hard, but they got a “cheater bar” shortly after I gave up
The contractor owner (Jim Hollar of Cold River Bridges) tried to push it in place, but not quite enough oomph! =>

15. Moving into position
<= as it turns out, the channel web was so thin that it “curled” a bit, causing an interference with the base of the roller unit so that it had to be skidded, rather than rolling
“X” marks the spot=>

Potential answers:
Name two unusual aspects of the relocation of the Mill CB
Motive power for relocation by oxen
Needed a large counterweight (bulldozer) to prevent it from rolling on its own

44. Yeah – you passed if you’re still here and awake!
