McNary Bergeron & Associates - Engineered Construction®

Project Highlights

The Yadin bridges project will alleviate traffic congestion in central Haifa by allowing vehicles to bypass the central part of the city. The project consists two main parallel segmental bridges and four smaller segmental access bridges. The project's close proximity to the Haifa airport necessitated using an erection gantry instead of cranes to prevent disruptions to air traffic.

Our Role

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, including integrated segment shop drawings, construction analyses, step-by-step erection procedures, and geometry control.
