Mumbai Trans Harbour Link

Mumbai Trans Harbour Link

The proposed Mumbai Trans Harbour Link (‘MTHL') has been planned to facilitate decongestion of the island city by improving connectivity between Island city and main land (Navi Mumbai) and development of Navi Mumbai Region. The link was envisaged about 35 years back.

Earlier three attempts in the year 2006, 2007 and 2013 by the Government authorities to take up the Project in various modes including PPP and EPC did not succeed.

Govt. of Maharashtra, vide G.R. dated 4th February 2009, decided that the project will be owned and implemented by Mumbai Metropolitan Region Development Authority (MMRDA). Govt. of Maharashtra, vide G.R. dated 8th June 2011, designated the project as Regional Development project.

Accordingly, the Mumbai Metropolitan Region Development Authority (MMRDA) has undertaken the implementation of the Mumbai Trans Harbour Link Project, connecting Sewri on Mumbai side to Chirle on Navi Mumbai side. This important link having length of about 21.8 Km is being implemented considering the importance of connectivity between the island city and the mainland. On completion of this project, the commuters traveling from Mumbai towards Navi Mumbai, Navi Mumbai International Airport, Jawaharlal Nehru Port, Panvel, Alibaug, Pune and Goa will not only be saving travel time but will also save in terms of fuel. This will also help alleviate the traffic congestion in the island city and facilitate development of Navi Mumbai area.

It has been decided to implement the project on EPC (Design-Build) basis with Official Development Loan assistance from JICA. JICA planned the project to be implemented 3 Packages of Civil works and 1 package containing the Intelligent Transport System. The Contract Agreements were signed on 26th December 2017 for Package 1 and 3 and on 19th January 2018 for Package 2. The letters of Commencements have been issued to Contractors of Package-1, Package-2 & Package-3 Contractors on 23rd March 2018.

3. Package-3

Construction of 3.613 km long viaduct section (CH 18+187 – CH 21+ 800) including interchanges at State Highway-54 and at National Highway-4B near Chirle in Navi Mumbai.

4. Package-4

Intelligent Transport Systems (ITS) includes Toll and Transport Management System and Equipment Installation for the Project. PQ for Package-4 is planned to be issued at the third Quarter of 2018.

 

Project Features

1. The MTHL which is about 21.8 Km long 6 Lane road bridge across the Mumbai Bay between Sewri in Mumbai and Chirle in Navi Mumbai. The link also comprises approach sections, interchanges, Ramps, ITS (Intelligence Transport System) and the other facilities necessary for access-controlled motorway.

2. As per IRC (Indian Road Congress) standards, the width of each lane of the Main Carriageway is 3.5 meters.

3. The maximum design speed along the link is 100Km/h.

4. As per the Japanese standards and other international standards for the bridges, JICA recommended provision of 2.5 meters wide shoulder on outer side of each carriageway and 0.75m at central median.

5. The bridge has one Interchange at Sewri on Mumbai side and at Shivaji Nagar & Chirle on Navi Mumbai side.

6. The foundations will generally be in pile foundation except in land portion where founding stratum is at shallower depth.

7. The substructure will be RCC cast in-situ.

8. The superstructure will be generally PSC box girders and the obligatory/navigation spans would comprise steel box girders.

9. Noise/View barriers will be provided on the link at stipulated locations.

2. Traffic Demand Analysis

At the opening year 2022, the daily traffic on the link is expected to be 39,300 PCU. The traffic is projected to increase up to 103,900 by 2032 and up to 145,500 by the year 2042. The daily breakdown of traffic on the link, by vehicle class, is presented in the Table below:

 

Vehicle Type Between Sewri Interchange and Shivaji Nagar Interchange Between Shivaji Nagar Interchange - Chirle Interchange
2022 2032 2042 2022 2032 2042

LCV: Light Commercial Vehicle; HCV: Heavy Commercial Vehicle; MAV: Multi Axle Vehicle

In the opening year 2022 the traffic flow on MTHL will represent a diversion of 10%on the traffic across Thane creek which will increase up to 16% in 2032.

The lane requirement was reviewed based on the forecasted result of future traffic volume. The result of the review shows that 6-lane will be required in 2032 (10 years after traffic opened to Public in 2022).

3. Implementation Technology

The major portion of MTHL structure is on marine stretch and partly is on land at both ends. The superstructure has different span configuration and of different type, viz., PC box girder with 50 m to 60 m spans which is typically applied on marine viaduct.

On the land portion, typically the PC box girder with 30-45m span is used.

At the locations such as navigation channels and utility (pipelines) crossings, in which long spans (150-180 m) are required, steel box girder bridges with steel deck is proposed with large block erection method to shorten construction period.

A list of the same is given in the Table below:

Details of Long Span Steel Bridges

Span(m) Number of spans
180 6
130-150 6
90-120 17
Total 29

 

Intelligent Transport Systems (ITS) comprises of

 Toll Management System(TMS)

• The toll management system shall collect toll from vehicles plying on MTHL. Two types of toll collection methods will be adopted; Electronic Toll Collection (ETC) and Manual (paying in cash)

• The lanes corresponding to these toll collection methods are dedicated ETC lanes and Manual lanes. Manual system toll collection shall be also be installed to ETC lanes for backup.

 Traffic Management System

• Traffic Management System is a support system to manage the traffic on MTHL safely and efficiently. The System consists of the information collection system including Closed-Circuit Television (CCTV), Emergency Call Box (ECB), Automatic Traffic Counter-Cum-Classifier (ATCC) and Meteorological Data System(MDS), and Information Dissemination System including Variable Message Sign (VMS)

• CCTV Cameras shall be installed at around three places per 1 Km, on both side of main route and the monitoring of the traffic condition of the whole stretch of MTHL will be enabled in the Traffic Control Centre and VMS displays the appropriate information for road users on the collated information.

• The Information collected by these devices shall be transmitted to the Traffic Control Centre through the medium of an Optical Fiber Cable laid in MTHL.

4. Technical Challenges in the project :

• Protection of underground and submarine utilities during construction.

• Erection of Segments at 30 m of height in marine area.

• Seismic Impact Analysis

• Wind Tunnel Test

• Long span Steel Bridges to allow the navigation channels and utilities.
