Bridges, Modi'in | Emek Ayalon

Modi'in is designed with a hierarchy of roads. Local roads are located in valleys with open space, and major arterial roads cross over valleys with as little disturbance to the natural open space as possible resulting in a number of long span bridges for road and rail. The design principle was to have as long an uninterrupted span as technical possible, to allow the bridge to visually "float" over the landscape. Therefore the location and modulation of columns supporting the bridge is a significant design consideration. Three examples completed by the Firm include:

Bridge Road 431

The bridge on Route 431 is actually a series of three parallel bridges connecting Route 1 with Modi'in, and crossing valley Anabah and part of the Ayalon drainage basin. The design span modulation between columns is 30m – 5@45m – 40m and a width of 17m and built on built on cast-in place columns.

Bridge Road 3

The design span module between columns is 30 – 170m – 30m and a width of 17m. Unique to this design is the 170 meter concrete arch support structure that supports the bridge deck. The design allows for a larger more dramatic free span and is suitable when bridging over narrow valleys with relatively steep sides. This is the largest bridge of its type in Israel.
