Golda Meir Bridge

The Golda Meir Bridge Project consists of two structures, a Northbound (NB) Bridge and a Southbound (SB) Bridge. Construction of each structure includes both precast segmental erected in balanced cantilever and cast-in-place portions supported on falsework. The NB Bridge is a two-span structure with span lengths of 84.1m and 87.6m. The SB Bridge is a three-span structure with span lengths of 58.4m, 66.4m and 82.3m. Each structure is comprised of concrete box girders ranging in depth from 2.7m to 5.2m. The box width measures a constant 14.8m for the SB Bridge, for the NB Bridge the width varies from 18.4m to 20.6m. Typical precast segments are 2.1m in length and weigh approximately 75 metric tons. For the NB Bridge, cast-in-place construction of the pier table extends 14.3m in each direction and is supported on falsework. A total of 23 pairs of precast segments are then erected in balanced cantilever with a ground-based crane. The completed cantilever prior to casting closures measures 121.2m in total length and is supported with temporary concrete props midway through construction.

The SB Bridge construction is similar to the NB Bridge with the exception of an additional pier at one end of the cantilever. Foundation work began in the Fall of 1998 and segment casting in January 1999, with the NB Bridge to be constructed first. After a short delay for permitting, the NB structure was completed in the spring of 2001.
