The five-point-one-five-kilometre elevated corridor in Porvorim is complete and will be inaugurated on September 9 with vehicular opening scheduled for September 11. PWD (NH) Executive Engineer Gajanan Desai said the six-lane structure is expected to carry at least 70,000 to 80,000 vehicles a day and is projected eventually to exceed 0.1 million (mn) vehicles. The engineering challenge of constructing the stretch is over, but the larger test will be how tens of thousands of vehicles actually use the route.

Officials caution that the key issues will arise at entry and exit points rather than on the elevated deck itself, with one critical pressure point likely towards Panaji where traffic will converge on the Mandovi bridges. The corridor is intended to move through traffic rapidly, but authorities will monitor whether faster movement simply shifts bottlenecks to adjoining junctions. North Goa traffic leadership has indicated that the project was conceived to cut congestion and travel time while acknowledging that only live operation will reveal any problem areas.

Desai said the road had been designed with a foresight of 25 to 30 years and with traffic projections that accommodate more than 0.1 mn vehicles, and that preparations have been made for vehicles continuing to use the surface road beneath the elevated section. Lane arrangements and junction crossings have been adjusted and traffic lights installed at critical junctions, although the signals have not yet been activated. The functioning of the surface network and junctions under the corridor will therefore be integral to the project’s success.

All categories of vehicles, including buses, heavy commercial vehicles and two-wheelers, will be permitted on the elevated route and the absence of CCTV monitoring at opening has been noted as a concern pending planned installations. Any breakdown or obstruction on the six-lane structure could affect traffic flow well beyond the vehicle involved, particularly during peak hours. Authorities describe September 11 as the beginning of a live test of the entire traffic system around Porvorim and have curtailed public walk access to one day ahead of the inauguration.
