Tunnel 21, State Highway 1, Marlborough

Conpavers have been contracting to HEB Construction on the re-alignment of the rail line, bypassing the Tar Barrel Tunnel (the oldest on this rail line), for over 1 year. It started with a small part of the project for drainage to be done and with that the confidence and exceptional work of the team has created further opportunities. HEBS Construction has asked the team to assist in the creation of green terra mesh walled embankments, excavating the inside of the overpass.
