GRAD Tunnel

The GRAD tunnel project was an over 3000 ft long tunnel rehabilitation project.  The tunnel had collapsed and we are working to re-open the tunnel and re-structuring.  This project also involved widening the tunnel and making it taller.  This design/build project involved completely re-shaping and re-structuring the entire tunnel for both stabilization and to add extra clearance.


We also added a new concrete tunnel floor and set up drainage collection for internal water sources.
