The project consisted of 1.2 miles of road reconstruction including some sections of full box reconstruction, sandwich-style reconstruction, and multiple drainage crossings, two pre-cast box-culvert installations, and one bridge deck rehabilitation.

This work also included building a 275’ retaining wall along the Swift River. NH DOT: Pinkham’s Notch, 1999 We excavated 84,500 CY of rock and pre-split 18.5 LF of holes to complete this project.
