DEER ISLE — The Deer-Isle Sedgwick Bridge is slated for $1.1-million five-month rehabilitation project to fix minor deterioration to structural elements.
The Maine Department of Transportation held a hearing Tuesday at the Deer Isle town office to inform residents about the proposed work, which will start in June.
The project will be preceded by another inspection, which will start mid-April and end in late May.
The DOT has contracted with the Boston-based firm TranSystems, which conducted the last bridge inspection in 2011.
Evan Lowell, assistant vice president for TranSystems, provided details of the project.
Crews will tighten “transverse stay cables,” which exist to “stiffen the bridge up,” Lowell said. “Some of these cables have gotten a little slack and they’re not providing 16 feet of vertical clearance,” for vehicles.
Also, finger joint supports, another bridge feature, have begun to crack and need to be replaced.
“Those cracks will continue to grow over time and could be a problem” Lowell said.
Another repair will be on the handrope stanchions, which is a safety feature for crews inspecting or working on the bridge.
Other repairs include floor beam knee replacement and fairings, which keep the bridge girder from flexing.
“Repairs will require single lane closures,” Lowell said. Most lane closures will be during the day time and reopen in the evening. However, there may be times where lanes are closed for a few days, he said.
“We have to hold the bridge up while we fix some things,” Lowell said.
