Carmel Tunnels Rupin Interchange Bridges

Project Highlights

The Carmel Tunnel project will alleviate traffic congestion in central Haifa by allowing vehicles to bypass the central part of the city. The $300 million project consists of two 5-km long tunnels through Mount Carmel, 5 conventional bridges, 6 segmental bridges, and 11 kilometers of roads which will link the tunnels to Israel’s highway system.

Our Role

These services include integrated segment shop drawings, construction analysis, step-by-step erection procedures, falsework design, and geometry control.
