The northbound lane of Grove Street will be temporarily closed between Route 101 and Laurel Street in Peterborough.
Work on a utility manhole that houses Fairpoint wires means drivers must circumnavigate the intersection by taking Granite Street or Hatch Street to exit Route 101 and head downtown.
“If all goes well – knock on wood – it’ll be over Friday,” Town Administrator Rodney Bartlett said.
The maintenance project began Wednesday after some confusion about a start date. Police Chief Guinard said after the road was closed for preparations on Monday there were very few issues, according to Bartlett.
The traffic-heavy stretch of road will be closed from 7 a.m. to 5 p.m. today and Friday and the plan is for work to be completed before the weekend.
