Al Qudra-Jabal Ali Lehab Rd Bridge
Improvement of Al-Qudra - Jabal Ali Lehbab Road Interchange Bridge Contract R1046
Ramps in the existing interchange were built with Tensar walls in 2005. The first upgrade in 2014 also incorporated Tensar structures. A further enlargement of the interchange to improve access to the local area required realignment of some existing Tensar structures, plus new structures to accommodate additional access ramps. In all the upgrades, the new structure had to be connected to the existing structure seamlessly. Tensar accommodated the existing underground utilities that ran across the area whilst designing the upgrades.
TensarTech TW1 ME system is a reinforced soil wall system which incorporates Tensar uniaxial geogrid reinforcement and modular block facing. Tensar designed the tiered reinforced soil walls with grey colour textured concrete blocks for the non-load bearing bridge abutment and for the new entrance and exit ramps. The TensarTech TW1 ME system was adopted to match the existing structures measuring a total face area of 3,300 sq.m.
