If a vacation in Goa is a fixture in your calendar, you’ll have observed that the state has modified a good bit in the previous few years. There’s a new airport to fly into, new bridges changing the previous, to not point out the broader highways. The newest improve to the state’s street community is the Porvorim Elevated Hall, focusing on a serious bottleneck on NH66. We got an unique alternative to expertise it for ourselves earlier than the official inauguration on Sep 9, and we introduced alongside a really ‘Goa’ automobile for the event – the MG Cyberster.
First, a little bit of fast historical past and geography. Nationwide Freeway 66 is a 1,640km arterial freeway operating from Panvel in Maharashtra to Kanyakumari in Tamil Nadu. 124km of NH66 is in Goa and, for years, Porvorim has been its most infamous bottleneck. The brand new 5.15km Porvorim Elevated Hall lets visitors sail clear over all that congestion beneath, connecting on to the Atal Setu bridge that crosses the Mandovi River. It guarantees to chop journey time between Mapusa within the north and the capital Panaji by as much as half-hour – a declare we got down to check.
Our place to begin was the north finish of the hall, a few kilometres away from Guirim village close to Mapusa. We began our stopwatch on the concrete ramp main up the PEC – one we might solely cease as soon as we crossed over the Atal Setu Bridge and entered Panaji. And even with 510hp and 725Nm on faucet and the street all to ourselves, we might be sticking to the 65kph velocity restrict.
From the concrete on-ramp, it is just a few metres till you drive onto the precise viaduct part, which is paved tarmac damaged up solely by growth joints. It isn’t fully straight both – the north finish has some beautiful sweeping curves. In a automobile just like the Cyberster, it’s fairly tempting to push by means of the bends however, exercising restraint, we as an alternative indulged within the joys of open-top motoring. The Cyberster drops its high in 10 seconds at speeds as much as 50kph, giving us very good views throughout. Importantly, it additionally raises the highest simply as shortly, which turns out to be useful throughout sudden showers.
From the motive force’s seat, the panoramic view of Porvorim’s greenery was fairly gorgeous – one thing you’ll by no means discover caught in visitors beneath. Drive on, and the street turns into arrow-straight, and also you begin to discover how shut among the buildings are to the hall. This proximity to adjoining constructions, together with the truth that NH66 needed to keep operational beneath, have been among the many greatest challenges the engineers confronted.
The 4.19km viaduct part is supported by 87 pillars. Every span operating between two pillars requires between 13 and 17 particular person pre-cast concrete sections. These sections are about 24 metres broad and weigh a whopping 120 tonnes every. They have been forged in a yard down the street, trucked to the positioning, hoisted 11 metres excessive and put in in place – all in a slim area between buildings with completely no room for error, whereas making certain minimal visitors disruptions beneath.
Contemplating the challenges, it’s fairly outstanding that the Porvorim Elevated Hall was accomplished in simply two years and 5 months. Under the principle construction, 10.30 kilometres of service roads and 28 minor junctions maintain native visitors shifting, whereas the hall sails above all of it. Additionally featured are eight field culverts and a rainwater harvesting system, so the monsoon doesn’t sluggish visitors down. A contemporary lighting setup with 515 streetlights has already been put in, whereas two high-mast lights and ten overhead gantries with cameras are to be put up quickly. All constructed at a price of Rs 641.46 crore.
Earlier than lengthy, we have been passing the Mall de Goa – shut sufficient to see the expressions on the faces of individuals within the meals court docket, as they watched the intense crimson Cyberster whizz previous their window. As we made our method down the off-ramp, the stopwatch confirmed that it had been simply over 4 and a half minutes. Heading in the direction of the Atal Setu, we merged with the handfuls coming from the diversion and have become a part of common visitors.
And similar to that, we have been climbing the Atal Setu bridge, which might take us throughout the Mandovi River and into Panaji. To the correct, gorgeous views of Panaji metropolis and Miramar seaside within the distance, and to the left, Outdated Goa with its historic church buildings, whereas above me, by means of the open roof of the Cyberster, panoramic views of the bridge’s iconic pylons and yellow cable stays.
Coming down the Atal Setu into Panaji, our stopwatch learn slightly below 10 minutes. Even in case you think about a few additional minutes for visitors as soon as the PEC opens, it equates to a real-world saving of about half-hour in peak hours, which is sort of vital. The truth is, the PEC is claimed to have a capability of 70,000 PCU, or passenger automobile items, per day, so visitors move is predicted to be fairly swift. Concurrently, it can scale back the burden on the service and different connecting roads beneath the hall, enhancing move for native visitors too.
The Porvorim Elevated Hall, together with different current infra initiatives such because the Atal Setu, the New Zuari Bridge and the widening of NH66, is predicted to spice up the economic system by enhancing intra-state connectivity to Goa’s industrial hubs, in addition to move between the airports and ports. It also needs to make commutes simpler for residents and alter the best way vacationers expertise Goa – much less time spent travelling, extra time to discover the seashores, the tradition and all the pieces Goa has to supply.

On the challenges confronted throughout building
This bridge is about 24 metres broad, however the correct of method is just 25 metres. Developing such a large construction when either side are already absolutely developed was very difficult. One of many greatest challenges was lifting the segments. Every phase is almost 24 metres broad and weighs round 120 tonnes. We couldn’t divert the visitors, so we needed to perform many of the work at night time. Throughout the daytime, we stopped heavy visitors in order that the segments may very well be lifted safely and regular visitors might resume shortly.
On different highlights of the undertaking
We tried to reap the rainwater to recharge the groundwater and enhance the water desk. There’s a median between the service roads beneath, the place we’re additionally planting timber. The hall’s rainwater harvesting system collects the water and directs it into this median. From there, the water flows into pits that we’ve dug and stuffed with aggregates and strainers, permitting the rainwater to percolate into the bottom. This helps harvest the rainwater and enhance the water desk on the plateau in the course of the monsoon.
On visitors and utilization
Under the hall, issues can be fairly totally different. As soon as round 50,000 PCUs of visitors are taken off the present four-lane street, there may very well be a bent for folks to park on these lanes. So, we must handle parking as properly. We’ve got streamlined the junctions and fully reworked the at-grade visitors move. Bikes are additionally allowed on the Porvorim Elevated Hall.

On the significance of the undertaking
The Porvorim Elevated Hall is definitely necessary not just for Goa but in addition for Maharashtra, Karnataka and Kerala. Porvorim had grow to be an issue as a result of it’s a congested and newly developed metropolis, with improvement on either side of the street. Even after the street was widened, it was very tough to handle, and it had grow to be an accident-prone zone. That’s the reason the Porvorim flyover was required, to make sure easy visitors on NH-66.
On the undertaking’s wider connectivity advantages
With the opening of Manohar Worldwide Airport in North Goa, there was a necessity to enhance connectivity in the direction of South Goa. Individuals arriving at Manohar Worldwide Airport and travelling in the direction of South Goa have been dealing with plenty of congestion. Now, that congestion can be diminished and this may undoubtedly assist tourism and car motion within the state.
Moreover, there can be higher connectivity between the airports and ports, which may have a optimistic financial impression. Additionally it is an important undertaking for the folks of Goa. Particularly these travelling between North Goa and the capital; they’ll save money and time, and their each day commute will grow to be a lot simpler.
On Goa’s future infrastructure plans
Virtually all of the initiatives on the Nationwide Freeway community in Goa have been accomplished. One of many remaining initiatives is the Borim Bridge, which can join the Ponda aspect. The tendering course of for it can occur within the subsequent few days.
We’re planning to enhance connectivity throughout rural Goa, from one finish of Maharashtra in the direction of Karnataka. We’re contemplating a hoop street for Goa, as a result of visitors at present comes into the inside areas and cities. Sooner or later, we wish visitors to have the ability to transfer across the inside villages and throughout the state with out having to enter the cities.
