New Esenler Viaduct (Section 1 and 2) has been projected to use in light rail transport system and after the construction, some manufactures have been left half finished. Retrofitting has become a necessity because of insufficient pile, ground and column capacity during the earthquake.
The construction site has located on the center so all kind of excavation, forage and jacketing in the site may have caused jam density. In order to minimize of the work in both viaducts, seismic isolators have been used. In addition, concrete rail beam has been used instead of ballast to lighting the bridge superstructure.
The U – bars have been used to increase rigid of superstructure torsion because of the low radius of viaduct horizontal curve. Difficulty of superstructure geometry has brought a special solution.
