Double deck structure proposed between airport, Chennai bypass

Driving from the airport and the upcoming mofussil bus terminus at Kilambakkam on the city’s outskirts, along GST Road, will soon be a breeze. Motorists can zip over a metro rail line or travel beneath it as part of a one-of-its-kind infrastructure project in the Chennai Metropolitan Area, providing commuters access to two different public transport systems.
The state highways department has tweaked the 10-kilometre long airport-Irumbuliyur elevated corridor project on GST Road to accommodate the proposed Chennai Metro Rail Ltd (CMRL) line till Kilambakkam.

While the facility will be a three-deck structure over grade separators or flyovers and remain at two levels along the rest of the alignment, the highways department will soon float tenders for preparing a detailed project report (DPR) that will decide if it will remain a two-deck structure or a threedeck facility along its entire stretch.
Three grade separators and a flyover, besides three foot-over bridges, are set to come up between the airport and Irumbuliyur junction. The elevated corridor will be 21 metres high when it is a threedeck facility and 14 metres tall when it runs along at two levels.

The decision comes after the Chennai Metropolitan Development Authority (CMDA), which had conducted a feasibility study report for the elevated corridor linking Chennai Airport and Chengalpet, decided to transfer the project to the highways department to execute it. CMDA will, however, continue to be the coordinator for implemenation, sources with the planning authority said.

The project is expected to be in tune with CMRL constructions proposed along the corridor. According to officials in the state highways department, the project will be confined to the stretch between the airport and Irumbuliyur since the road beyond comes under the purview of the National Highways Authority of India (NHAI).
