HIRAM BRIDGE

The Hiram Bridge Project consists of dual bridge structures that cross over a major highway and adjacent railway. The total length of the crossing is approximately 250-m. with the structures running parallel to one another for about 160-m. before the alignment of one bridge diverges following a horizontal curve.

The structures are concrete box girders with a depth of 2.4-m. and top slab widths of 12-m. for one structure and 13.7-m for the other. Span lengths for the two bridges vary from 22-m. to a maximum of just over 56-m. Box girders are to be precast segmental with typical segment lengths of 3.14-m. The total number of segments for both bridges is over 150. The erection method for this project is to be the balanced cantilever method using an overhead gantry. The overhead gantry planned for this project was previously used on the Ayalon Bridge Project, which also involved Finley McNary Engineers.

The successful bidder for the Hiram Bridge Project is Malibu/Ashcrete of Israel.
