Projects

Gall Zeidler Consultants work closely with clients and owners to develop tailored tunneling solutions for each unique project. The sample project briefs below highlight our broad spectrum of tunneling experience and knowledge.

Highway Tunnels

Our highway tunnel project settings range from dense, urban environments to environmentally sensitive rural locations. The recently completed three–lane Fort Canning Tunnel in Singapore displays tunneling under very shallow overburden while the Devil’s Slide Tunnels project features construction of two two–lane tunnels along scenic highway US 1 near Pacifica in California.
