HARRINGTON. — A portion of Route 1A will be closed for bridge culvert replacement starting Oct. 7.
A lighted sign has been posted near the site warning motorists of the coming closure of Johnson Bridge, which runs over the Flat Bay River. The closure will last through Nov. 11.
The road is expected to be open but restricted to one lane from Nov. 12-19.
- Buck Construction was awarded the $997,700 contract, said Paul Merrill, spokesman for the Maine Department of Transportation.
Construction will be suspended for the winter, with work resuming in late June with surface paving and project cleanup, Merrill said.
Michael Wight, an engineer with MDOT, said the work is taking place in the fall because of environmental requirements, restrictions on when the contractor can pave, lead time for getting materials, contractor availability and the weather.
“Work in the water is limited to between Sept. 15 and March 15 to minimize impacts to fisheries,” Wight said. “The contractor can do base paving only until Nov. 15, when temperatures are 50 degrees or warmer.”
Large precast concrete culverts like the one being used in this project are custom built and this one won’t be done until the week of Oct. 14.
The contract [includes] time to get the base paving done but not the surface paving,” he said. “The surface paving needs to wait until early summer 2020 after paving plants reopen and the weather warms up.”
Merrill said motorists can use one of two possible detours. The first involves staying on Route 1 in Milbridge and following that through Cherryfield and Harrington to Route 1A northeast of the project site.
The second option is to use Route 1A to Dorman Road and follow Dorman Road back to Route 1A. The second detour is restricted to local traffic only, he said.
