ECO PARK
The park has been divided into three broad parts; 1)
ecological zones like wetlands, grasslands, and concrete forest, 2) theme
gardens and open spaces, 3) and concrete recreational spaces.[3] The Eco Park
is further divided into different sub-parts consistent with the various sorts
of fauna planted. The copies of the Seven Wonders of the planet have also been
made for people to go to during this park.[4] consistent with the plan, the
park will have different areas like wild flower meadows, a bamboo garden,
grasslands, tropical tree garden, bonsai garden*, garden , Cactus Walk*, a
heliconia garden*, a butterfly garden, a play area and an amphitheatre(*-yet to
be added).[4] Further, there's decide to develop an eco-resort in
public-private partnership, and can also include a neighborhood where
handicrafts from different a part of the state are going to be exhibited.[3]
The park was inaugurated on 29 December 2012 by Mamata Banerjee.[5][6] Etc. The
Eco park is found along the main highway (part of Biswa Bangla Sarani) in
Action Area - II of latest Town at 22°35′55″N 88°28′03″E, 10 km faraway from
Kolkata International Airport. The park is surrounded by the Kolkata Museum of
recent Art on the North, the upcoming Central downtown and International
Financial Hub on the east, the Kolkata International Convention Center, HIDCO
Bhawan and Rabindra Tirtha on the south and existing human settlement of
Jatragachi/Hatiara on the West.[3] it's well connected with VIP Road and EM
Bypass. Buses are available from Ultadanga, Baguiati, Kolkata Airport, Salt
Lake and Chingrighata.
Vidyasagar Setu, also referred to as the Second Hooghly
Bridge, may be a toll bridge over the Hooghly River in West Bengal , India,
linking the cities of Kolkata (previously referred to as Calcutta) and Howrah.
With a complete length of 823 metres (2,700 ft), Vidyasagar
Setu is that the first[1] and longest cable-stayed bridge in India, as 3rd
Narmada Bridge in Gujarat is an extradosed bridge. it had been the second
bridge to be built across the Hooghly River; the primary , the Howrah Bridge
(also referred to as Rabindra Setu) 3.7 kilometres (2.3 mi) to the north, was
completed in 1943. Named after the educationist reformer Pandit Ishwar Chandra
Vidyasagar, it cost ₹3.88 billion to create . The project was a joint effort between
the general public and personal sectors, under the control of the Hooghly River
Bridge Commissioners (HRBC).[2]
The importance of the bridge has increased manifold since
2013, because the West Bengal State Secretariat had shifted it's office to
Nabanna, located adjacent to the bridge on the Howrah side.
Initially, under the toll collection regime of the HRBC,
daily traffic was recorded to be a minimum of 28,000 vehicles and a maximum of
39,000 vehicles in 2000, but fell to a maximum of around 30,000 vehicles by
December 2002, when the management of the tract was handed over to a personal
firm. Subsequently, the daily traffic reached a minimum of 45,000 vehicles and
a maximum of 61,000 vehicles by early 2008, against a maximum capacity of
85,000 vehicles per day. the first management of the toll revenue collection by
HRBC was consequently criticized for corruption and significant loss of
revenue.[3]
Population and business activity grew rapidly after India gained independence in August 1947. the sole link across the Hooghly River, the Howrah Bridge, between Howrah and Kolkata, was subject to much traffic jam , with over 85,000 vehicles a day . This necessitated planning for a replacement bridge across the river in order that it could hook up with the main cities of Mumbai (Bombay), Delhi and Chennai (Madras) through the national highways located on the brink of the bridge.
The design of the bridge differs slightly from other
bridges, which are of superload composite construction. The difference is
within the load design concept adopted for this bridge and concreting of the
side spans through with support provided by the intermediate trestle. The deck
is meant with a grid structure of girders. One set of girders are at the top
and another set within the middle, which are braced by girders spaced on a mean
at 4.2 metres (14 ft) centre to centre.[13]
A deck crane was used for the development of the most span of the bridge. A specially designed crane of 45 tonne capacity was wont to erect the pylons of the bridge.[13] The steel utilized in the bridge weighs about 13,200 tonnes.[13] The pylons, which are 128 metres (420 ft) tall , are designed as free standing portals.[13] they're given two cross portal members, one at rock bottom and another at the highest , below the pylon head. The deck is connected to the top piers by bolts embedded within the chambers of the piers. Pylons made from 4 m × 4 m (13 ft × 13 ft) steel boxes of riveted construction were raised on the 2 side spans of the bridge; one set is on the Calcutta side and therefore the other is on the Howrah side.[13] The six pylons on the Calcutta side of the bridge were installed using 75 MT and 50 MT cranes, while on the Howrah end, one 50 MT crane was used. Anchorage of the pylon with the bottom of piers was effected through Dywidag rods, duly anchored within the piers.[13] Cables were erected from the four pylon heads with the assistance of 32 MT hoist frames. The hoist frames were mounted on top of every pylon. Sheave blocks, winches and snatch blocks were wont to facilitate the lifting, and cables inside the pylons were stressed with jacks. Pressure grouting was performed to fill the voids between
