PROJECT HIGHLIGHTS: RUPIN INTERCHANGE BRIDGES
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.
McNary Bergeron & Associates is partnered with Zachoot Engineering of Tel Aviv, Israel to design all of the segmental bridges as well as provide construction engineering services for the Rupin Interchange. These services include integrated segment shop drawings, construction analysis, step-by-step erection procedures, falsework design, and geometry control.
