Elevated road to BIA in the making

It will help motorists reach the Devanahalli airport in just 20 minutes

Posted On Friday, August 13, 2010 at 04:12:28 PM

A signal-free corridor comprising a stretch of elevated expressway, four underpasses and two flyovers at a cost of Rs 600 crore will be built connecting Hebbal flyover to the Bengaluru International Airport (BIA), the development work on which has commenced a couple of weeks ago.

Soil testing work on the signal-free road on this stretch began a couple of weeks ago

The construction work for the NHAI-led project will start in end October. Once the corridor is ready in a couple of years, it will make it easier and quicker to travel to the airport.

This connectivity to the airport will have a toll fee.

NHAI project director R K Gupta said, “Currently, soil testing is on. The project has been awarded to Navayuga Constructions. If all goes well, the project will kickstart by October-November.”

As per the project plan, the 3.2 km stretch from the Hebbal flyover to the beginning of Yelahanka bypass (near GKVK) will be an elevated stretch. From the Yelahanka bypass to the trumpet inter-change (the gateway to BIA), all the major junctions will be made signal-free. To this end, two flyovers will come up at the Kogilu Cross and Vidyanagar junctions, while four underpasses will come up at other crucial junctions.

Officials said the Rs 600-crore project has a 24-month deadline and will allow motorists to reach the airport within 15-20 minutes from Hebbal, as against 45 minutes now. Notably, it will be the first six-lane elevated highway corridor in the city.

Currently, Bangalore has two elevated corridors — the Electronics City expressway and the Tumkur Road expressway — both of which are four-lane. The airport expressway will be built on a single pier. NHAI officials said, “Six-lane flyovers are constructed on two piers. However, with improved technology, we are set to construct it on a single pier. The advantage is it takes up less space.”

The project was announced by then Union minister of state for surface transport K H Muniyappa a few years ago. However, due to recession and other issues, it has been a delayed starter. With the airport having only a road link as yet (work is yet to start on the high-speed rail link), the Hyderabad NH-7 is over-utilised.

There are already tollbooths erected near the BIAL trumpet interchange. So are they planning to collect 2 tolls for the same road to BIAL???

Yes Piling Work is in Progress in the Middle .This PPP project Includes Navayuga to build drainage's on either side of the road, bus bays ,foot paths apart from elevated Road .From Yelahanka surface road will be widened to 10 lanes till trumpet junction

Avinash ,thanks for the pics.
Just a question, Is this projects also involves converting existing 4 lane hebbal flyover to 6 lane.

Motorists bearing the brunt of slow moving peak-hour traffic on Tumkur Road every day can expect no relief for two more months as work on the signal-free elevated corridor here and the axis road to Nelamangala has been delayed.

Officials of the National Highway Authority of India (NHAI) said that the work hit a roadblock in the form of two 66kv electrical transmission lines falling along the route of the 4.5km-long four-lane elevated expressway.

“We had written to the Karnataka Power Transmission Corporation Limited (KPTCL) to shift the lines, but did not receive any response from them for 15 days. After that we decided to take up the task ourselves. Under KPTCL’s supervision, we are increasing the height of the towers above the transmission lines.

Once this is done, the last mile connectivity between the two segments at Peenya will be completed and the road will be thrown open to the public,” said a senior NHAI official on condition of anonymity.

Work on the elevated expressway on NH-4 was started in November 2007 at an estimated cost of Rs775.7 crore. Once completed, it will connect to a 15km long, six-lane axis control toll road leading to Nelamangala, giving commuters seamless connectivity along a four-lane main carriageway, three-lane service road and four-lane elevated expressway.

To enable motorists to take U-turns along this stretch, NHAI has provided an underpass for every two kilometres.

Urban planner Dr AS Kodandapani said that though land acquisition and other technical issues delayed the project, it would ease traffic flow. He said that parts of the city along that stretch were fast developing and the density of traffic was expected to rise by 30%. The NHAI had to be prepared.

The flyover would also ease the flow of traffic plying to and from Tumkur, Davangere, Hubli, Dharwad, Belgaum and from the states of Maharashtra and Gujarat.

After the completion of this project, NHAI will take up the task of converting the four-lane Hebbal flyover to six-lane, and make NH-7, from Hebbal flyover to the international airport, eight-lane wide and signal-free.

Here it is more clear

Bangalore's Hebbal flyover set to go wider

Published: Wednesday, Jan 13, 2010, 8:37 IST
Here’s some good news for Bangaloreans. The busy Hebbal flyover that connects the Bengaluru International Airport to rest of the city will soon become six-lane wide, thus giving respite to the beleaguered traffic in the area. This is not all. The entire stretch of the road leading to the airport will be signal-free, thus enduring smooth traffic movement.

The Bangalore Development Authority (BDA) is handing over the Hebbal flyover to the National Highway Authority of India (NHAI) for making it six-lane wide. Furthermore, NHAI is also preparing a detailed project report on making NH-7, from Hebbal flyover to international airport, eight-lane wide and signal-free.

BDA engineer R Sreenivasa said that they had discussed the issue with the officials of NHAI and Bruhat Bangalore Mahanagara Palike (BBMP) and government orders have also been issued. The BDA will clear the debris below the flyover and landscape the area at a cost of Rs1.9 crore, before handing it over to the NHAI for the widening work. Of the 5.6 km flyover, the NHAI aims to add piers on a kilometre stretch to make it six lane.

The BDA had constructed the flyover in coordination with the NHAI. The agency aims to develop 9.6 acresbelow the flyover and hand it over. A statue of Kempegowda will also be installed here.
BDA engineers point that the passenger car units (pcu) was 12,364 vehicles during peak hours in 2009 which is likely to increase to 13,291 in 2010.

BBMP chief engineer (major roads) Chikkarayappa said, the road till Hebbal belongs to the Palike and it will be handed over to improve upon the existing infrastructure. Furthermore, NHAI is also conducting surveys to construct flyovers at five junctions on the highway towards airport, to make it signal free. This will ensure seamless connectivity, NHAI manager, technical, Ravi Sudhakar told DNA. The project for widening the flyover, widening the highway till airport and constructing flyovers is estimated around Rs600 crore. It will be taken up on a public private partnership (PPP) model.

Experts point out that there is a need to undertake this project as the vehicular movement is rapidly increasing. Advisor to the government of Karnataka for traffic, transportation and infrastructure, MN Sreehari said that once road is widened, traffic will increase and thus lead to road congestion. He felt that as compared to BBMP and BDA, the NHAI has better expertise and knowledge it was a good idea to assign them this task.

Thanks sunil for the link,yes by adding piers existing flyover can be widened but why is BDA acting so foolish it says it will complete landscaping works before it hands it over to the NHAI for expansion,don't they realise that widening works will destroy the landscaped areas?How foolish :nuts:

They will do some substandard landscape worth crores(on paper) which will anyhow get destroyed & now one will question the about it, ultimately the kickback money will fill their pockets.
