Because the bridge will expand and contract
due to temperature changes, a joint must be installed
so that there will not be a large crack in the pavement
on each end of the bridge. The type of joint for this
bridge is called a Asphaltic Plug Joint.
First 18" of pavement is removed over the end of the
bridge at each abutment. A steel plate is placed over
joint, and then a rubber type material is hot poured
in the joint and ¾" aggregate is mixed in the hot
rubber. This allows a very smooth riding joint that is
also very durable.

Photo of retaining wall in late 2006.
Dismantled the stone retaining wall that was in
front of the house just west of the Fire Station.
The two 24" maple trees that had to be
removed when the power lines were re-routed.
Winterset removed the stumps, and in this photo
you can see the sleeves for the concrete which
will hold a new hand rail. The steps will not be redone.

Plans called for raising the Sewer Manhole cover
on Prince Street that was supposed to be in the new
roadway just west of the bridge (almost under the bridge).
It wasn't there. We spent two days with the town running
camera's up from the next manhole. It was very hard to
locate. We finally found it.
It had been buried years ago in about 10' of embankment.
And because it was further north than it was supposed to be,
we had broken part of the pipe right next to the manhole.
We were very lucky last summer when driving the steel
sheets to the temporary detour abutment. We came close
enough to break the pipe, but not plug it.
In the end, it cost us three days of work and instead of just
raising the lid, we had to build a new manhole from the
base up.

Winterset worked the winter on projects in Bristol New Hampshire and the bridge across the Connecticut River in Haverhill NH. They resumed construction of the bridge over the I-91 in Hartford this spring also.
There has not been any activity on this project since December. The project wintered well with no apparent problems. The concrete rail has many small cracks that are typical with this type of rail. In fact, even though there are many cracks, there are less cracks than other projects have had using this same design. Maybe the use of AA concrete aggregate with HP-B concrete has helped to reduce the cracking??
