Famous for experiencing giant waves during monsoon season, it attracts locals and tourists alike throughout the year. Worli Sea Face features a number of significant attractions that include the Worli Fort, Haji Ali Dargah and Bandra-Worli Sea Link (Rajiv Gandhi Sea Link).

History

  • Northern bridge of BWSL within the foreground seen against the Worli skyline. read from Bandra Fort
  • Sunset read of Bandra Worli Sea link from Dadar Chowpatty spanning over Mahim Bay
  • Mahim Causeway was the sole road connecting the western suburbs to Mumbai's central city district. This north-southwestern passageway became a bottleneck and was extremely engorged at peak hours. The Western pike project was projected to span the whole western lineation of Bombay to ease congestion. The Bandra–Worli Sea-Link, a bridge over Mahim Bay, was projected because the initial section of this pike system, providing another route to the Mahim Causeway.
  • The Mujeeb Acharwala Bridge connects the intersection of the Western specific main road and Hindu Vivekanand Road in Bandra to the Khan Abdul Ghaffar Khan Road in Worli. From Worli Seaface, it connects to Mumbai's blood vessel Annie Besant Road.
  • The project was commissioned by the geographical region State Road Development Corporation restricted (MSRDC). The contract for construction was awarded to the Hindustan Construction Company (HCC), with project management diode by the united kingdom offices of Dar Al-Handasah.
  • The foundation stone was arranged  in 1999 by Bal William Makepeace Thackeray. the first set up calculable the value the value.6 billion (US$93 million) to be completed in 5 years. however the project was subject to varied public interest litigations, with the 5-year delay leading to the value escalating to ₹16 billion (US$220 million),with the extra interest price alone accounting for ₹7 billion (US$98 million).

Planning

  • The overall project consisted of 5 elements, shrunk severally to accelerate the general schedule.
  • Package I(1): Construction of a flyover over Love Grove junction in Worli
  • Package II(2): Construction of a interchange interchange at the intersection of the Western specific main road and S.V. Road in Bandra
  • Package III(3): Construction of solid approach road from the interchange to the parcel of land on the Bandra aspect beside a public promenade
  • Package IV(4): Construction of the central cable-stayed spans with northern and southern viaducts from Worli to the parcel of land at the Bandra finish
  • Package V(5): enhancements to Khan Abdul Gaffar Khan Road
  • Package IV was the most section, with the opposite packages providing supporting infrastructure.

Geology

Surveys of the sea bottom below the planned route were conducted before the bridge style commenced. The marine earth science beneath the bridge consists of basalts, volcanic tuffs and breccias with some intertrappean deposits. These square measure overlain by fully weatherworn rocks and residual clay. The strength of those rocks vary from very weak to very robust and their conditions vary from extremely weatherworn and broken, to fresh, huge and intact. The weatherworn rock beds square measure additional overlain by transported soil, carbonate arenaceous rock and skinny bed of coarse grained conglomerate. the highest of those strata square measure overlain by marine soil layer up to 9m thick consisting of dark brown clay silt with some fine sand superimposed weatherworn, dark brown volcanic rock boulders embedded within the silt.

Design

BWSL was designed because the initial cable-stayed bridge to be made in open seas in Asian nation. thanks to the underlying earth science, the pylons have a posh pure mathematics and also the main span over the Bandra channel is one among the longest spans of concrete deck tried. reconciliation these engineering complexities with the aesthetics of the bridge conferred vital challenges for the project.

The construction of the viaducts were the heaviest formed segments to be in-built Asian nation. They were designed employing a span-by-span technique victimization overhead framework through a series of vertical and horizontal curves.

The 20,000 weight unit Bandra-end span of the upper deck is supported by keep cables at intervals a really shut tolerance of deviations in set up and elevation.

The Bandra–Worli ocean Link was the primary infrastructure project in Bombay to use unstable arresters. These can change it to resist earthquakes activity up to seven.0 on the Richter scale.

Foundation and substructure

The construction of the bridge's structure conferred major engineering challenges. These enclosed the extremely variable geotechnical conditions thanks to the underlying marine earth science of the sea bottom. At times, even for set up space of one pile had a extremely uneven foundation bed. additional complications enclosed the presence of a variable seacoast zone, with elements of the muse bed exposed in tide and submerged in high water.

The foundations for the BWSL's cable-stayed bridges comprises one hundred twenty concrete piles of two,000 millimetres (6.6 ft) diameter. Those for the viaducts comprises 484 piles of one,500 millimetres (4.9 ft). These 604 piles were driven between 6m and 34m into the substrate in geotechnical conditions that varied from extremely weatherworn volcanic material to huge high strength rocks.

Pylon tower


BWSL's largest pylon towers square measure 128 m (420 ft) high.
The largest pylons for the bridge comprises diamond formed 128 metres (420 ft) high concrete tower that includes flaring lower legs, convergency higher legs, a unified tower head housing the stays and a unceasingly variable cross section on the peak of tower.

The bridge's pylon towers bit by bit decrease in crosswise with height. they need horizontal grooves each 3m tall, that permissible inserts. Vertical grooves within the circular sections need special type liners, furthermore as need attention for de-shuttering. The tower legs square measure inclined in 2 directions, that conferred challenges in alignment and climb of troopers. Construction joints were permissible at 3m intervals solely.

To build the pylons, Doka of Republic of Austria was commissioned to create a custom automatic climb shutter formwork system, supported their SKE-100 automatic climb shutter system. This was fancied on website and used to execute all tower leg lifts below deck level.

Pre-cast yard

The pre-cast yard was settled on rescued land. The yard catered to casting, storing and handling of 2342 concrete-steel pre-cast segments for the project. The storage capability demand of the yard was concerning 470 formed segments. because the space on the market was restricted, the segments were keep in stacks of up to a few layer
Structure

Criticisms
  • The Economic Times criticized the delays and shoddy construction of Bandra–Worli ocean Link. First, value|the value|the price} wasn't the projected ₹3 billion however really cost value billion or concerning twenty third cost. Second, the project was five years delayed.
  • The monetary categorical has reportable that even eight years once it had been thrown open, the daily average traffic on the Bandra Worli ocean Link — is smaller than a 3rd of the first estimate. In fact, the rise in revenues over the years — Rs sixty six.62 large integer in 2010–11 to Rs seventy.28 large integer in 2011-12 and to Rs seventy one.04 large integer 2012-13 — has been fairly little Latest statistics show the daily traffic forecast the six-kilometre, preponderantly cable-stayed bridge has born by over Martinmas within the past year, from 45,952 vehicles in 2011–12 to forty,808 in 2012–13. Over four years from 2009 to 2013, the daily vehicle count has born by over 16 PF. High toll is taken into account a serious causative issue to individuals finding the bridge, a less engaging travel possibility. conjointly cursed  ar congestion towards Pedder Road for south-bound traffic and new flyovers that move north–south traffic on the jap flank of town, particularly the two.6-km Lalbaug flyover
  • There was conjointly criticism directed at the crumbling paved surface on the bridge presently once completion.
  • The capability of the bridge is restricted thanks to a bottleneck at the Worli (south) finish of the bridge. whereas the bulk of the four.7 km (2.9 mi) length has four lanes in every direction, the Worli finish has solely 2 lanes for a length of roughly one.2 km (0.75 mi). This results in backlogs for southward traffic, particularly throughout morning peak hours.
