Mangaluru, May 23, 2016: The work on the much-delayed Railway underbridge (RuB) on Mangaluru-Bengaluru National Highway (NH 75) at Padil appears to be moving with the construction wing of the Southern Railway working on installing temporary girders beneath the lines.
Once completed, the RuB would facilitate four-lane traffic from Padil till B.C. Road thereby eliminating the perpetual traffic bottleneck at the existing two-lane RuB on NH 75 at Padil.
Movement of trains on the Mangaluru Junction-Padil section was suspended for about seven hours last Sunday to facilitate the work while another rail traffic block of the same period would be effected between 3 p.m. and 9.30 p.m. on May 29.
Railway workers were busy inserting temporary girders beneath the lines to pave way for pushing concrete boxes beneath the lines.
The National Highways Authority of India (NHAI), which has resorted to box pushing technology to build the RuB, had deposited about Rs. 1.2 crore with the Southern Railway for installation of temporary girders.
However, the Southern Railway had informed the NHAI that there was no need for temporary girders and the work could go ahead, said NHAI’s Project Director Samson Vijay Kumar. Sensing that the boxes cannot be pushed beneath the lines without temporary girders, the Southern Railway recently decided to install the same, he said.
While the railway workers were busy installing the girders, the NHAI is in the process of pushing concrete boxes beneath the tracks.
Mr. Vijay Kumar told The Hindu that with the railways blocking train traffic again next Sunday, temporary girders would fully be in place. Thereafter, the concrete boxes can easily be pushed to form the RuB. Completion of the RuB work might take another month, he added.
The four-lane RuB was a part of NHAI’s Port Connectivity Project that was launched in 2012. Despite the incomplete stretch of four-lane at Padil and the consequent frequent traffic jams, the NHAI has been collecting toll at Brahmarakootlu toll plaza near Bantwal, much to the chagrin of road users.
Meanwhile, the NHAI has taken up cut slope protection work on the bypass connecting Padil and Nanthoor (NH 75 and NH 66) via Maroli and Bikarnakatte.
The NHAI has adopted soil nailing technology for the work instead of the conventional retaining wall construction. The work is under progress at Maroli at present, which would also be done in some other patches along the bypass.
