No prizes, for guessing this. It is Mumbai Sea Link. South Mumbai is connected to North Mumbai via the sea-link. It was inaugurated in the year 2009 and is a boon for people of Mumbai.  Prior to this, Mahim Causeway was the only road connecting the western suburbs to Mumbai’s central business district. This north-southwestern corridor became a bottleneck and was highly congested at peak hours. The Western Freeway project was proposed to span the entire western coastline of Mumbai to ease congestion. The Bandra–Worli Sea-Link (BWSL), a bridge over Mahim Bay, was proposed as the first phase of this freeway system, offering an alternative route to the Mahim Causeway.

Here is a view from the car over this cable stayed bridge. A beautiful view of the sea as you drive over it. BWSL, officially called Rajiv Gandhi Sea Link, was designed as the first cable-stayed bridge to be constructed in open seas in India. It was designed by Seshadri Srinivasan and constructed by Hindustan Construction Company, India.

The construction began in the year 2000. The construction of the bridge’s structure presented major engineering challenges.The pylons have a complex geometry and the main span over the Bandra channel is one of the longest spans of concrete deck attempted. Balancing these engineering complexities with the aesthetics of the bridge presented significant challenges for the project.

The superstructure of the viaducts were the heaviest precast segments to be built in India. They were built using a span-by-span method using overhead gantry through a series of vertical and horizontal curves. The 20,000 tonne Bandra-end span of the bridge deck is supported by stay cables within a very close tolerance of deviations in plan and elevation. The Bandra–Worli Sea Link was the first infrastructure project in Mumbai to use seismic arresters. These will enable it to withstand earthquakes measuring up to 7.0 on the Richter scale.

An engineering marvel keeps Mumbai connected.
