ALSTEAD — Five months after heavy rains washed out a portion of Route 12A, the New Hampshire Department of Transportation has reopened a closed section of the state road as the $1.8 million road reconstruction project nears completion.
The half-mile stretch of Route 12A in Alstead has been closed since it was severely damaged by flooding in late June.
The repaired section was opened to alternating traffic Tuesday afternoon.
DOT spokesman Bill Boynton said Wednesday motorists should expect alternating one-way traffic with flaggers for the remainder of this week as additional clean-up work continues. Final paving of the state road is planned for spring of 2014.
After a washout, typically DOT prefers to reopen roads as soon as possible; however, since this stretch of Route 12A has washed-out again and again, including during the 2005 floods, DOT decided to tackle a full reconstruction and not just a quick repair job.
While there are no homes on this stretch of Route 12A, its closure has nonetheless been disruptive to residents of the area, Boynton said.
"There's always a certain urgency to get roads reopened and get traffic back on them because it is disruptive," but residents understood DOT was taking an in-depth response to the situation, he said. The steep geography of the area has always been an issue for Route 12A, he said.
R.S. Audley Inc. of Bow was hired to conduct the $1,786,097 emergency repair project on the stretch of Route 12A that runs just north of the intersection with Walpole Valley Road, and proceeds north for approximately one-half mile.
The project involved 15 individual repair sites, Boynton said, and included a full roadway reconstruction, shoulder and ditch line repair, slope repairs, construction/installation of a retaining wall, box culvert and drainage, ledge removal, guardrail replacement and paving.
