About Mumbai:
Mumbai previously known as Bombay in English is the capital of the Indian state of Maharashtra. It
is the most populated city in India, and the fourth most populous city in the world, with a total
metropolitan area population of approximately 20.5 million. Along with the neighboring urban
areas, including the cities of Navi Mumbai and Thane, it is one of the most populous urban regions
in the world. Mumbai lies on the west coast of India and has a deep natural harbour. As of 2009,
Mumbai was named an Alpha world city. Mumbai is also the richest city in India, and has the
highest GDP of any city in South, West or Central Asia.

3. Project Background:
During the past two decades the existing western corridor stretching from Bandra to Cuffe Parade
has become highly congested and the traffic volumes have already reached saturation levels,
needing immediate capacity augmentation. The construction of Rajiv Gandhi Sea Link taken up by
MSRDC is a partial solution to the problem. Appreciable relief can be achieved if this sea link is
further extended up to Nariman Point and Cuffe Parade. The proposed Western Freeway is a north
– south sea link connecting the Worli end of Rajiv Gandhi Sea Link (BWSL) to Nariman Point and
further to Cuffe Parade.
Project Phases:
Western Freeway Sea Link Project Phase II i.e. from Worli to Nariman Point has been further
phased out as follows; as per the directives of Empowered Committee, Government of
Maharashtra.
Phase Description Status
Phase II-A Worli to Haji Ali
section
Appointment of BOT Entrepreneur is in progress. Tenders invited
and last date of receipt of bids is on 29.11.08
Phase II-B Haji Ali to
Nariman Point
Section
Consultant M/s Arup-CES JV is exploring various alternative
alignments against direct sea link and its feasibility study. Pre-
feasibility report is expected by the end of November 2008. In
feasibility study various alternatives like tunnel from Haji Ali to
Nariman Point, a sea link from Haji Ali to Priyadarshini Park then
through Malabar Hill Tunnel etc. will be studied. After getting
detailed feasibility report the tender of this phase will be called for
on BOT basis.

4. Phase II-A
Project Location: The alignment starts at Worli end of Bandra – Worli Sea Link, runs parallel to
Khan Abdul Gaffer Khan Road shoreline (Worli Sea Face). The alignment then traverses through
Love Groove Outfall and upto Haji Ali Bay and lands on Lala Lajpatrai Road at Rajni Patel Chowk.
The alignment is to be provided with interchanges at Worli and Haji Ali.
Salient Features:
It is estimated that an eight-lane bridge from Worli to Haji Ali interchange may be required.
Length of Bridge 3.20 kms
Project Base cost Rs. 1120 Cr (at 2007 prices)
Source if financing Equity, Debt and Grant if required
Recovery of expenditure By way of Toll, Tariff and user fee
Project schedule Four Years
Work is proposed to be executed on BOT Concessionaire’s alternative design. It is preferred to
provide a modern traffic monitoring Control and surveillance system and State – of – the – Art toll
collection system in the bridge.
WFSL Project Benefits
1) Significant savings in travel time due to increased speed and reduced delays at intersections.
2) More comfort in driving with reduced mental tension and overall improvement in quality of
driving.
3) Reduced number of accidents.
4) Air and noise environment will improve along the thickly populated existing corridors.
Concentrations of CO and NOx are expected to reduce by around 70 percent and 45 percent
respectively. The noise level would reduce substantially.
5) Eco – friendly viaducts may add to the aesthetics of the coastal area.
6) Diversion of traffic on sea link will provide relief to local roads in the high – density areas.
7) No obstruction to fisherman's activities as there will be ample clearance for fishing boats and
fish landings will not be disturbed.

Further
Research
to
be
done:
• Use of Aimsun software to design and simulating road model.
• Modifying the flow of traffic to avoid traffic jams.
• Placing signals where required.
• Studying the causes of traffic jams and rectifying them.
• Preparing a detail report of the study made of the same.
