Bridges, connectivity and challenges

Context: The completion of the Guwahati Gateway Ghat and the
North Guwahati Connecting Bridge marks a pivotal moment for Assam, enhancing
connectivity across the Brahmaputra and promising economic growth for the
region. While the infrastructure projects bring many benefits, they also raise
significant post-construction concerns, particularly in relation to the
Brahmaputra’s natural flow, the potential impact on North Guwahati, and the
preservation of the historic Aswaklanta temple. Additionally, there are key environmental
challenges, including the interaction between the Bharalu river and the
Brahmaputra, and the efficiency of pumping activities that are essential for
flood management.

Key
points

·      
Overview: The Guwahati Gateway Ghat and North Guwahati Bridge
mark progress in Assam’s connectivity but also bring environmental challenges.

·      
Significance: The proposed Guwahati Gateway Ghat aims to unlock
Assam’s growth potential by establishing India’s first state-of-the-art
riverine ferry terminal. This groundbreaking project is set to address travel
disruptions caused by the suspension of ferry services due to rising water
levels in the Brahmaputra River.

Modern
Terminal Complex- Facilities
for both passenger and freight operations. Berthing provisions with approach
trestles and steel link spans. Floating pontoons to manage water level
fluctuations year-round.

Terminal
Building Infrastructure- Two fire
water tanks and additional tanks for raw and clarified water. A sewage
treatment plant with a 100 KLD capacity, along with a sewage collection pit and
tank for waste management. Pump-house for consistent water pressure. Switchgear
room for electrical infrastructure. EV chargers for buses and a dedicated ferry
supply station. Two intake bore wells and a river water pumping system for fire
water tank storage.

Passenger
Facilities- Designated boarding and
disembarking areas. Ticket counter and entry lobbies for smooth operations. Baggage
scanner for efficient security checks. VVIP room with toilet, first aid, and
baby crèche facilities. Food court and storeroom for dining and shopping. Separate
toilets for men and women, locker room, and electrical room. Waiting lounge
with 96 seats. VVIP observatory deck and a public observatory deck with river
views. Cafeteria and air handling unit (AHU) room for comfort.

Riverine
Infrastructure- Four intermediate dolphins
and four berthing dolphins supported by steel piles. Two berthing pontoons with
canopies and four intermediate pontoons. Link span featuring a steel bridge
with a 20-kW solar panel system and a transparent roof for natural light. Berthing
capacity for six catamaran vessels.

·      
Economic
Impact: The development of the
Guwahati Gateway Ghat is expected to have a transformative effect on Assam’s
inland waterways. By integrating high-quality passenger and vehicle ferry
services with inland water freight transport, the terminal will significantly
enhance regional connectivity and stimulate economic growth.

·      
Challenges: One of the key risks is the potential for riverbank
erosion caused by changes in the Brahmaputra’s natural flow. The introduction
of bridge foundations into the river could alter the water’s course, increasing
pressure on the banks, especially around North Guwahati. Aside from physical
damage to the sur rounding structures, the construction of the bridge and the
ghat is likely to affect the overall flow of the Brahmaputra, especially during
peak monsoon seasons. Another critical issue is the problem of silt deposition,
which could become a great er challenge due to the changes in the Brahmaputra’s
movement caused by the construction.
