FINAL EIA EMP Construction of New 4-lane Bridge (Parallel to the Chapter -2 Project Description REPORT Existing MG Setu) with its approaches from km 0/000 to km 14/500 across river Ganga on NH-19 at Patna in the State of Bihar on EPC mode
2 Project Description 2.1 Introduction
The existing Mahatma Gandhi Bridge (MG Setu) was constructed about 34 years ago over the Ganges River in order to connect Patna to the other side of river. After completion, it became part of NH-19. It is one of the longest bridges in India.
The Hajipur –Patna section of NH-19 is in Bihar. The NH-19 originates at UP Border and terminates in Patna via Chabra. The present project road is about 15 km length i.e., from km 207.20 (Hajipur) to km 222 (Patna). There is existing MG Setu which is four lane Bridge of 5.575 km length between km 212.72 to 218.295 with approaches on Patna side 3.5km length and Hajipur side 5km approximately. The government has planned for construction of New 4-lane Bridge (Parallel to the Existing MG Setu) with its approaches from km 0/0 (KM 222 of NH-19) to km 14/500 (Km 207.2 of NH-19) across river Ganga on NH-19 at Patna in the State of Bihar on EPC mode.
2.2 Type of Project: Since this is a construction activity for making a bridge over the Ganga River, it falls under the Category B of Township and Area Development project 8(b) as per EIA notification 2006. The total area of the proposed project is 6,45,361 sq-m and break-up of the same are as follows:
Built-up area of Bridge - 2,08,095 Sqm, Approach road – 2,23,857 Sqm, Viaduct – 69,309 Sqm, Toll plaza – 1,44,100 Sqm
2.3 Need of the Project The existing Mahatma Gandhi Bridge (MG Setu) was constructed about 34 years ago over the Ganges River in order to connect Patna to the other side of river. After completion, it became part of NH-19. It is one of the longest bridges in India.
The bridge has 46 spans each with length 121m. Each span has two cantilever beams on both sides which are free to move at the ends. The Spans are connected by using a Protrusion which is free to move longitudinally also along the river flow. In upwards and downwards direction it is such that it allows vibration to transfer smoothly to the next span while vehicular movement without much discreteness. Due to heavy traffic movement and being the only bridge to cross Ganges river the bridge is used heavily now. Hence it has started vibrating with higher amplitude than it was designed to. Also, in many spans the cantilever beams were found to have sagged at ends. So, the Setu is now stressed beyond limit under the weight of heavy vehicles constantly plying over it from Patna and North Bihar and threatening its existence. Poor maintenance, coupled with wear and tear caused by the unprecedented surge in traffic, has made the structure vulnerable. If a larger crack develops, it will sever the lifeline between the state capital and north Bihar. Considering the significant role, the Ganga Setu has been playing for decades in people's lives in this region, it is unimaginable to think of Patna skyline without Mahatma Gandhi Setu. The MORTH has also undertaken rehabilitation of existing MG Setu in a separate work.

2.5 Size or Magnitude of Operation
This project includes the Construction of 5634 m long 4-lane major bridge at 38mts upstream of the existing 4-lane Mahatma Gandhi Setu (M.G. Setu). The new major bridge shall be provided as extradosed bridge having minimum main spans of 242.13m with appropriate end span. The new bridge shall have minimum navigational requirement of 100m for horizontal clearance between piers and vertical clearance of 10m above HFL. The navigational clearance shall be secured in consideration of old bridge’s piers as well. Total approaches of 8.866 km length (3.380 km on Patna side and 5.486 km on Hajipur side) shall be developed as eight lane divided carriageway highway (4 –lane connecting new Ganga Bridge and 4 – lane connecting old MG Setu) along the project alignment. The Patna side approach road includes new 1565 m long 4 - Lane viaduct (parallel to Existing Elevated structure), one 112 m long 4 - Lane ROB (parallel to existing ROB) and Hazipur side approach road includes new 101.60 m long 8 – Lane Flyover, one Toll Plaza (minimum 16 + 16 lanes including 1+1 ODV lane), Mahatma Gandhi Setu Museum, One LVUP, 3 Nos. of VUP and also have service roads, footpaths etc. in the project.
As this is a big construction project, salient features of the project components are being described hereunder. A copy of the DPR is being attached as Annexure-2 for the reference. The project Highway shall be developed as 8 – lane divided carriageway from km 0/000 to km 14/500 on NH-19. The new 4 - lane Ganga Bridge and its approaches shall primarily cater one side traffic from Patna to Hajipur, whereas existing 4 – lane MG Setu and its approaches shall primarily cater other side traffic from Hajipur to Patna after completion of the Project.

The EIA report is being prepared in compliance to the ToR issued by SEAC Patna and the Environmental Clearance is likely to be obtained by the mid of 2021. Proponent will start the construction work only after obtaining the necessary clearances and permissions.
2.7 Technology and Process Description
New Ganga bridge proposal parallel to existing MG Setu is given described below.
A new 4-lane Bridge across River Ganga is proposed parallel to the existing Mahatma Gandhi Setu on the upstream side. Out of various alternatives of the bridge types, 242 m span Extradosed Bridge was found technically feasible option. It has been decided in principle that the span arrangement of the proposed new 4-lane Ganga Bridge will be same or in multiples of existing span of the existing MG Setu.
Detailed bridge features are summarized as below table.

2.10 Utilities 2.10.1 Water Requirement It is envisaged that during construction work, 560 labours and other staff may be present at the site and hence the drinking and sanitation water requirement during construction period is estimated to be 560 x 45 lpcd = 25.2 KLD.
Water for construction purpose will be obtained from nearby STP/ETP and only recycled water will be used for the construction work. No fresh water utilization is proposed for construction work. Typically 60 KLD water is required for construction of 1,00,000 sq-m of area going to be constructed in a day. Water for dust suppression and green belt will be met through recycled water from the system process.
However, when the project gets completed and becomes fully operational, it is expected that total 200 people will need water for their daily activities. Hence, total water requirement during that period will be 200 X 45 LPCD = 9 KLD. It is envisaged that water for green belt during operation phase will be 6 KLD and for dust suppression is 5 KLD. Hence, to total water demand during operation phase is estimated 20 KLD.
A water balance diagram for construction and operational period are given as follows

2.11 Power Requirement During construction phase DG sets will be used for power supply. It is expected to have DG Sets of 2X 250 KVA, 2X 125 KVA, 2X 100 KVA,1X62.5 KVA, 1X33 KVA capacity for power. However, once the project becomes functional power will be sourced from Bihar State Electricity Board.
