The Brihanmumbai Municipal Corporation (BMC) is progressing towards completing the Mumbai Coastal Road Project's first phase by launching girders to connect Worli with the Bandra Worli Sea Link (BWSL). The girders, ranging from 44 to 136 metres, are being installed in segments to bridge the 850-metre gap. This process, undertaken in February, utilises barges anchored in the Arabian Sea due to the lack of land strips for launching.
Shallow waters and dense bedrock at Worli pose challenges, requiring 24-hour monitoring for safe girder launching during favourable sea conditions. The project faced a hurdle when the fishing community demanded a wider navigation span, leading to the adoption of 'Bow-String' girder bridge design instead of additional pillars.
The girders, fabricated at JNPT (Raigad) and Ambala, are transported for assembly onsite. Work to bridge the gap between Coastal Road�s Worli end and the Sea Link commenced, with two girders placed on the southbound arm, and the remaining two to be launched soon. Girders on the northbound arm will follow, with a targeted May deadline for opening both arms of the Coastal Road. The bridge's length will be 850 metres, comprising approximately 270 metres of steel and the rest concrete.
Despite the progress, the opening date for Coastal Road's southbound arm remains uncertain, initially slated for February 19. Sources suggest it may open just before the Lok Sabha poll code of conduct takes effect.
In summary, BMC's final launch of girders for the Mumbai Coastal Road Project aims to connect Worli with the Bandra Worli Sea Link, bridging an 850-metre gap. Challenges include shallow waters and dense bedrock, necessitating careful scheduling of girder launches. The fishing community's demand for a wider navigation span prompted a design shift to 'Bow-String' girder bridges. Girders are fabricated off site and transported for assembly, with work progressing to open both arms of the Coastal Road by May. Despite progress, the opening date for the southbound arm remains uncertain, potentially occurring just before political regulations come into effect.
