Our Solution

ViaBridges was contracted to design the rehabilitation of Palmchim, Sorek and Pleshet railroad double-bridges along Israel's Highway 4, on the country's coastline. Requirements included geometry adjustments to accommodate a new third lane, and seismic retrofit upgrading to comply with latest standards and rehabilitaion including sealers and coating.

Success story 1: To suite a smooth lane transition at normal driving speed, one shoulder of each bridge was cut and re-cast on a raised plane. Then MMA technology was used for paving the top coat, providing a dual solution both as a waterproof sealer and as a friction overlayer (instead of the permeable and slippery concrete paving). ViaBridges is the first in Israel to use MMA, and results were immensely successful.

Success story 2: To ensure minimal interference with traffic, while ensuring bridge resistance to seismic activity, ViaBridges developed a new type of a fuse. This fuse comprises four hidden poles, placed under the approach ramps of each bridge. This simple yet effective solution was embraced with much success.

Success story 3: During the project execution, Palmachim bridge was struck by a passing semi-trailer truck that completely destroyed three of its girders. Traffic was detoured due to the hazard, and ViaBridges was asked to provide a quick solution. The girders were replaced with and improved design, especially designed with new shellow beams, to increase clearance height.
