Overpassing a highway interchange or intersection, a flyover is a high-level road bridge. In a building of this type, one road crosses another. In order to cross over an obstruction without obstructing the path below, flyovers are built. Perhaps a road, highway, or railroad was required for the crossing.           Â
Bengaluru flyover construction
There are currently 44 flyovers in the city. Officials of the Bruhat Bengaluru Mahanagara Palike reported receiving Rs 404 crore for the flyover project. The flyover projects at Ittamadu, JC Road, Sarakki, and West Of Chord Road are expected to cost around Rs 230 crore and take 18 months to complete.
Typically, flyovers are built over significant traffic intersections. There are 8 major directions of traffic flow at a major intersection: 4 are straight-line or direct traffic flows, and the remaining 4 are right turn traffic flows in each direction.
A flyover only addresses two straight or direct traffic flows, whereas it would suggest that the traffic at the junction might be successfully managed using signals. As a result, the junction’s traffic flow would be facilitated (wherein the traffic signal has to still address the 8 directional traffic flows.
The current study has evaluated how the construction of a flyover will affect the problem of traffic congestion in terms of traffic decongestion, time savings, fuel savings, and emission reduction. Additionally, a flyover has been built over four signalised intersections in Nagpur’s major business district.
Shivananda Circle Flyover, which was planned in 2011 and completed in 2017, was intended to be made accessible to vehicles by the end of 2021. However, the project is still not finished since the flyover design is being changed to prevent lawsuits over property acquisition.
At Sivananda Circle is Bangalore’s first steel flyover. An estimated Rs 50 crore was spent on the 493 m-long bridge.
As a result of the highest court’s order, the flyover’s length was also raised from 326 to 493 metres. The project, which located nearby Kuara Krupa Guest House, is expected to cost roughly Rs 50 crore to develop, which is double the initial sum approved for the construction work.
Following complaints about design issues, the flyover was shut down in August. Later, in order to resolve the problem, the Bruhat Bengaluru Mahanagara Palike turned to the IISc for assistance.
In addition to the steel flyover, four more bridges are being built nearby to the west of Chord Road, but progress on those projects has been sluggish due to a labour shortage following the COVID-19 outbreak.
The Bruhat Bengaluru Mahanagara Palike (BBMP) is altering the design because private landowners have threatened legal action and refused to give up their land for the down ramp. The municipal organisation has decided to minimise the length of the ramp rather than waste time on a legal battle.
According to officials, it will save the property owners about Rs 40 crore in payment.The traffic at the Shivananda circle signal, which is frequently congested with commuters from Malleshwaram, Majestic, and Chalukya circle, is anticipated to be relieved by the construction of this steel bridge. The public opening of this bridge has been keenly anticipated by Central Bengaluru commuters.
Officials of the Bruhat Bengaluru Mahanagara Palike (BBMP) anticipate this week’s complete operation of Bengaluru’s much-delayed Shivananda Circle flyover. The 493-metre flyover, which was inaugurated last month, was swiftly closed down as a result of complaints from drivers who had a bumpy ride because of design issues.
In response, the local authority sought advice from specialists at the Indian Institute of Science (IISc). Last week, a flawed alignment of the structure was corrected by removing a piece of the flyover’s asphalting.
While one section of the flyover is operational, the other side will soon be made accessible to the public, according to officials. To make sure that the flyover is level and provides a smooth ride, the BBMP also intends to add another layer of asphalt.
Despite resistance from the community, the Shivananda flyover work order was issued in June 2017, with a nine-month completion target. The project’s initial estimated cost of Rs 19 crore was increased to Rs 60 crore a year later.
