The Chennai Metro Rail Ltd (CMRL) and its contractor Larsen & Toubro have built a cool steel truss bridge at Guindy to allow the metro trains on the Washermenpet-Airport line to pass over the Suburban Railways’ tracks.
The bridge is 105 meters long. It was fabricated at a yard and then assembled on the piers of the approach station area. It was launched using the “nose launching method” where the superstructure is slowly launched towards its final location and then lowered over the designated pillars. A similar bridge was recently built in Delhi for its new Pink line (See: Delhi Metro Launches Steel Bridge For Pink Line Under Blue Line).

The bridge is located right next to the Guindy Metro station as you can see both above and below.
The steel bridge can also be seen in this excellent aerial video of the metro line shot from a plane coming in to land at the airport. Electrification and signalling installation is currently in progress on this section and trials from OTA to Little Mount are expected to commence in October (See: Chennai Metro to start testing Little Mount – OTA line in October)
