I assume (and will try and confirm) that the closure is to take care of the sink hole that developed during one of those big rain storms. I don't have addresses but its near the MVD Well.
Confirmation found on the Town's front page (website):
http://www.merrimacknh.gov/node/1565The emergency replacement of the culvert located near 30 Turkey Hill Road is scheduled to begin on June 21, 2010. Turkey Hill Road will be closed for approximately 5 days to facilitate the repair. A detour route will be set up utilizing McQuestion Road, Baboosic Lake Road, and Joppa Road Extension - See attached map for the detour route.
During the work it is expected that one of the two water lines will need repairs, causing water to be out in the Pilgrim Ave and Beacon Drive neighborhoods. The outage would be between 8:00 AM and 4:00 PM. Effected homes will be notified by the Merrimack Village District.
Please refer questions on the project to the Department of Public Works, Highway Division at 423-8551
