The $170 million Road 1 Motza Bridge near Jerusalem and Tel Aviv, Israel is part of the major highway system and is the main road into Jerusalem. It is one of the most important infrastructure projects that will be carried out by the Ministry of Transport and Roads Company in the coming years.
This challenging project is adjacent to religious and historical archeological sites between two tunnels; the segmental bridge design provided a method for building a structure with minimal impact to this culturally significant area. FINLEY worked within the extremely restrictive allowances for site access to develop a construction plan to serve the project requirements and allow for construction to proceed within a tight construction schedule.
The bridges are two 800 m precast segmental bridges with three lanes in each direction. Spans range from 40 to 60 m and a bridge deck height range of 3 to 25 m above the valley floor. The bridges will be erected in balanced cantilever using a combination of a unique overhead gantry and ground-based cranes, which provided cantilever stability during segment erection.
FINLEY provided bridge design and construction engineering. Services included pre-bid design, superstructure design, construction engineering, geometry controls, temporary works design, and on/off-site technical support during construction.
