The 30 metre long ‘U girder’ (a precast structure used for construction of viaduct) is the longest span launched here so far and it has been done for building the viaduct in OMR. It has been launched using an advanced puller axle system for the transportation and erection at a height of 20 metres between Okkiyampet and Karapakkam in OMR, according to a press release.

In this stretch from Nehru Nagar to Sholinganallur where in one of the locations the ‘U girder has been placed, L&T has been carrying out the construction. Officials said, this puller axle is a special fabricated trailer which was made with 12 axles, each with 8 tyres totaling 96 tyres.
