Sand Patch Tunnel

Linear Notching / Portal Caps

The Sand Patch Tunnel is located in Larimer Township. A portion of the linear notching will require remedial strengthening of the liner with shotcrete, grout and rock bolts given the moderately deep dimensions of the notches. The majority of work will be completed inside of the tunnel, with little earth disturbance surrounding the tunnel.
