Monday and Tuesday were beautiful days in New Gloucester, and the start of construction on the Stevens Brook culvert replacement is off to a good start.
Some of the first steps are to build a road to the rear of the site to allow the cofferdam (temporary dam) to be constructed and a by-pass pump system installed to move upstream water from the brook around the construction activities. The temporary road crosses very soft sediment and requires three layers of thick wooden mats to keep the equipment from sinking.
The 2,200 cubic yards of sediment being removed averages two feet thick. Town of New Gloucester trucks are hauling it to the designated disposal site on Long Bennett Road.
The first two days of construction only required reducing Gloucester Hill Road to one lane, minimizing disruption. Wednesday the start of work to remove the existing culvert will necessitate closing the road completely.
