Jennifer Paul, a construction manager with MDOT’s multimodal programs office, said that as part of the ongoing project to construct the new bridge, slated for completion in the summer of 2014, engineers will be monitoring the integrity of the existing structure while it is remains in use and scheduling needed repairs.
Engineers will use ground-penetrating radar to examine the integrity of the bridge roadway that day, Paul said.
On the following three days, June 13 -15, workers will perform repairs on the bridge during the day, and traffic will be limited to one lane at a time and a maximum vehicle weight of five tons. Tractor-trailer traffic will be rerouted during those times.
Additional repair time has been set-aside for June 19 through 22, although not all of that time may be needed, Paul said.Paul said that both the Maine and New Brunswick transportation departments would conduct the inspection work.
Repair work on the bridge will consist of joint and curb replacement, other work on the deck, and roadway patching. Paul added that allowances would be made for emergency response vehicles needing access to the bridge on the days when repairs are being done, but would not be possible on the inspection date on June 12.
Variable message boards have been installed adjacent to the bridge to inform drivers of the planned closures. Paul added that the MDOT would produce informational flyers, which customs officials would provide to drivers in the days leading up to the closures.
MDOT staff also reminded residents that all work is weather dependent, and motorists should take note of any updates posted on the roadside message boards.
