Our eighth trail work day was one of the most challenging that anyone could remember.  The goal: Move a 45' long 14' wide truss bridge from Stark to Berlin and then install it on abutments across the Dead River.  It took 4 excavators, a bucket loader, a large truck and trailer and a dozen volunteers but at the end of the day, the bridge was sitting safely over the river.

Loading the Bridge

The bridge was stored in a gravel pit owned by Mason Excavating.  the pit owner, Harley Mason supplied a large bucket loader and excavator that would be used to lift the bridge onto the trailer.  At 7:00am, the crew arrived consisting of Eric Johnson, John Higgins, Pete Johnson and Larry Gomes.  They installed heavy duty 1/2 inch chains on each corner of the bridge connected to a steel I-beam.  The team then rigged a lifting chain to the I-Beam.  Once the chains were fitted, they were attached to the loader and the excavator so the bridge could be lifted into the air and oaded onto the trailer.

The transport truck and trailer was donated by Chapman Steel and Demolition in Gorham, NH.  The crew consisted of Bud Chapman driving the transport truck and Matt Lentendre driving an escort truck.  Bud lined the flat bed trailer up with the bridge and the excavator and loader lifted it up high enough so the trailer could be backed under it.  The bridge was then lowered onto the trailer and strapped down for its ride to Berlin.  For safety reasons, all of the lifting chains and support beams were removed for the trip.

Unloading the Bridge

After a 12-mile ride to Berlin, the Berlin Police Department provided traffic control on the city streets and the bridge arrived safely at the Notre Dame Arena followed in by the rest of the loading crew.  Waiting behind the Arena were two excavators; one donated by Matt Godbout of MG Excavation and the other from the Berlin Water Works.  Also waiting at the Arena parking lot were several more volunteers including Shaun Roy, Pete Peare, Roger Richard, Mike Godbout and Dalton Binette.

After Chapman's truck pulled into position, the volunteers got the chains and steel beams reinstalled and the two excavators lifted the bridge while the truck pulled out from under it.  The two excavators then inched their way towards the river and dropped the center of the bridge on top of the abutment on the Arena side of the river.  MG Construction had a second excavator on the opposite side of the river that was then used to pull the bridge the rest of the way across the river.

Installing the Bridge

Once the bridge was resting on the both shores, Matt proceeded to build the abutment on the western shore using interlocking concrete blocks.  The bridge was then lifted onto the blocks and the crew found out that blocks were not quite square with the bridge.  So they lifted the bridge off, set it down on the river bank and repositioned the concrete blocks.  The bridge was then lifted back into place and this time it fit perfectly!  The crew marked where the concrete blocks had to be cut to allow the pads to sit flat and then the blocks were cut and concrete chipped out to create a flat surface.

The final step of the installation was putting back some of the rocks that were along the shoreline of the river and installing silt fencing to prevent any loose soil from washing into the river.

Here are some pictures taken on Friday preparing for the move:

Matt Godbout of MG Excavation dumps a truckload of stone to form a solid base for the bridge abutments on the west side of the river.

 

After the stone was raked out and brought to a rough elevation, Asst. Trail Master Larry Gomes used a compactor
supplied by MG Excavation to compact the stone into a solid surface.

 

To figure out where the west bridge abutments needed to be located, Matt and Larry used set of wire rope cables
attached to 4 plywood boards that represented the 4 steel pads on the bridge.  To figure out where the west
abutment needed to go, the eastern pads were fastened down on top of the east abutment and cables were pulled
tight and the location of the pads on the west side of the river were marked.  The little yellow device on top
of the center block is a laser level supplied by MG Excavation.

 

Matt Godbout uses a receiver that is capable of picking up the signal from the laser level across the river.  Using this signal
he was able to adjust the height of the abutment base on the west bank so it matched exactly to the height of the base on the east bank
.

 

This a a close up view of the laser leveler.  Also note that these cement blocks are "keyed" to keep them from moving.  The top keyway
sticking up 
on the outside blocks had to be cut away so the steel bridge pads would sit flat on the top of the block.

 

Matt uses his concrete saw to cut slots in the "key" sticking up from the blocks.  These pieces were then knocked out
with a hammer creating a flat area on the top of the block for the steel bridge pads.

Here are some pictures taken on Saturday of the bridge move:

Chains installed in each corner of the bridge go up to a steel I-Beam where another longer chain will be used to lift the bridge.

After lifting the bridge and moving the cement blocks that it was sitting on off to the side, the bridge is finally ready for transport.

The steel lifting beams and chains have been removed and the bridge is strapped into place ready for a ride to its new home.
 

The big rig pulls out of the gravel pit in Stark heading for Berlin.

 

The bridge arrives safely at the Arena.

With the chains and lifting beams installed, Larry is all smiles knowing the bridge is nearing the end of a several month long journey.

 

With the bridge hanging in the air over the truck, the Chapman crew members Matt Lentendre and Bud Chapman
pose for a quick picture with their family members that they brought along so they could see the old bridge being moved.

 



With the bridge lifted high in the air, the truck pulls out from under it so it can be set down.

 



The two excavators driven by Rick Mackenzie and Matt Godbout work their way slowly up the trail making sure to dip their booms
down below the overhanging wires.

 

With the bridge safely across the river, its time to start building the west abutment.  Roger guides the first block into place.

 

Matt sets down the final block with Mike and Roger guiding it into place while Larry looks on.
 

Its finally time to see if it fits!  The blocks on the west bank were off by a few inches so the crew decided to take the time
to reset them so they were perfect.
 



With the bridge in place, it was time for the welding crew from Berlin Spring to jump into action.  Shaun Roy uses a torch to
remove one of the angle iron braces he welded into place to keep the bridge from racking while Eric Johnson and Pete Peare wait
to carry the angle iron off the bridge when it has been cut loose.
 

Shaun welds a piece of heavy duty angle iron up against one of the cement blocks.  There are three of these angle irons on each
side of the bridge that will keep the tops of the cement blocks from tipping in towards the river if they are hit with frost in the winter.
The bottom of the blocks are keyed so they should not move even in the worst winter weather.

will be added to ramp up to the bridge.

 

After a long day, everyone loads up and gets ready to head home.
 

Our sincere thanks go out to all the volunteers and companies who donated time, equipment and expertise to this project.  Without each and every one of you, this project could not have been done!
