The famed two-lane highway had been closed since Irene struck on Aug. 27. The Category 1 storm carved a new inlet north of Rodanthe and several breaches in the road that have required extensive repairs and restoration.
State officials said last week the road would be reopened by Tuesday.
Repair work has included the construction of a temporary bridge over a new inlet on the north end of Hatteras Island. Engineers hope a permanent solution will be ready by 2016.
