Tunnels

MSV has been involved in the design of cut and cover and bore tunnels of various sizes and shapes. We have worked with many reputable specialty Tunnel Consultants on numerous tunnel projects in the past. The tunnel projects we were involved in are cut and cover Tunnel 15 feet diameter for Cedar River Pipeline Crossing State Route 405 at Renton, Washington, USA, and bored tunnel about 0.5 miles long 30 feet diameter at Interstate 90 at Seattle, Washington, USA, which carries automobile traffic at two levels and pedestrian traffic at third levels.
