The Brihanmumbai Municipal Corporation (BMC) is set to launch the crucial 120-metre girder with a bowstring arch to bridge the gap between the Coastal road with the Bandra-Worli sea link by April 16 or 17. The girder will connect the southbound arm of the coastal road with the Bandra-Worli sea link.
M M Swami, the deputy chief engineer of the coastal road, said three girders of 46-metre, 44-metre and 60-metre spans have already been launched in the southbound arm of the Coastal road.
“On April 12, the 120-metre bowstring arch bridge, assembled at Nhava village jetty, will be loaded in a barge (a floating platform) that will start moving towards the site at Worli and will reach by April 15-16. Depending on the weather conditions, the arch bridge will be placed on the pier by April 16-17, Swami was quoted by Hindustan Times as saying.
Eight girders will bridge the gap between the coastal road’s Worli end and the sea link on the southbound and the northbound arm with an arch bridge.
The bridge between the coastal road and the sea link will be 850 metres long, of which 270 metres will be made of steel and the remaining concrete.
Vipul Surana, the team leader at AECOM, the BMC’s general consultant for the south coastal road project, stated that a forecast of good weather was needed before the lifting operation of the 120-metre girder arch bridge could be carried out.
“A weather condition with no heavy rain, lightning or wind speed of 20 metres per second or less is considered good weather. For safety purposes, adequate lighting should be made available to ensure that the operations can be continued at night if necessary. Safety gear and equipment will be made available at convenient locations,” Surana was quoted by Hindustan Times as saying.
“One of the four girders is already launched in the northbound arm. The other two girders are ready at the Nhava assembly yard and will be launched later in April. The arch for the north-bound arm will be launched in May in a fair-weather window,” he added.
