He said they replaced a one-lane bridge with a two-lane unit.
“The Inverset bridge saved costs; it was free. The estimated savings was about $250,000 on this one project. The construction time is saved because of the Inverset panels, short-term construction costs, because you don’t have any cure time on site.
“Overall, it was a very successful project.”
Storms and red flags started taking out more bridges last year, LaVigne said, following DOT inspections and tropical storms Lee and Irene.
“There were two devastating storm events, washing out 10 bridges. Bridge inspections brought unexpected red flags. DOT offered to help again with more Inverset bridges, so we went down and looked at them.”
Besides the Loj Road Bridge, three county bridge projects got Inverset spans: Gouchie Bridge in Minerva, which was a red flag, and Hulbert Bridge in Lewis and Lacey Bridge in Keene, which were both Irene-damaged.
“Lacey Bridge before Irene was a restrictive flow, a maintenance headache,” LaVigne said. “It was a hodgepodge bridge that was on a low-volume road that we tried to keep open over the years. It seems like I was ... there just about every other year fixing something. After Irene, it was completely missing.”
After construction with the Inverset, there was no stream restriction, and the span width was increased 30 percent, he said.
The bridge in Minerva had to be done fast, he said, because it had been closed, so they got Adirondack Concrete of Keeseville to do the work.
“Gouchie Bridge was actually programmed for the Inverset when we picked them up in the summer. We were planning on replacing the bridge, and then we got an unexpected red flag with a 24-hour response, and so we had to close the bridge. We had to react very quickly. We actually built Gouchie Bridge in four weeks.”
