Mumbai Metros derailed after quarries shut, workers can’t find raw material Work on

Work on the city’s Metro lines has hit a roadblock as stone quarries that supply a bulk of construction material have been shut since April 1.

Officials of the Mumbai Metropolitan Region Development Authority (MMRDA) — the nodal agency for the projects — said the 70 Navi Mumbai quarries were their largest source of raw materials. They said the pace of construction work on the Dahisar (East)– Andheri (East) Metro 7 corridor and the Dahisar–DN Nagar Metro 2A corridor has been hit as 60% of construction material comes from quarries in Turbhe.

Nalin Gupta, its managing director said the material available is just 25% of what the firm needs. “A lot of projects have been hit. The MMRDA is trying to come up with a solution,
Darade said that as the leases of several quarries have expired, the regional planning body plans ask the state government to hand them over to the MMRDA

“We will ask the state for two quarries, which will help us finish projects faster,” he said.
