The Western Railway has allotted 142 days of power blocks to Mumbai Metro One Private Ltd (MMOPL) for the construction of a bridge through which the Metro will traverse above the Andheri railway lines.
The permission comes after nearly 18 months of negotiations between the Mumbai Metropolitan Region Development Authority (MMRDA), MMOPL and the Western Railway.
The 180-m-long steel bridge, which will be built at the cost of Rs35 crore, will cross the railway line from Andheri (West) to Andheri (East).
The 142 traffic and power blocks for the construction of the steel bridge range from a minimum of one hour 55 minutes to a maximum of four hours.
“The blocks will take place between mid-night and the early hours when railway traffic is minimal or absent. The blocks, we are certain, will facilitate timely construction and completion of the critical steel bridge,” PRK Murthy, chief, transport and communication, MMRDA said.
The agreement also expresses the possibility of allowing work, with or without speed restrictions, while trains are running, subject to prevailing traffic conditions and availability of engineering time. MMRDA and MMOPL will pay charges for permission to cross railway land.
They will pay charges equivalent of 99% of the present market value of the land plus nominal charges of Rs1,000 per annum for a period of 35 years, extendable for a further period of 35 years to the railways.
They will also pay the overhead crossing charges of Rs50,000 per annum for the area of land and Rs1 lakh per annum for a two-track metro for each 100-m stretch of crossing.
Western Railway has also stipulated that work can be undertaken only in the presence of its own employees.
The bridge will be constructed in three spans of 61 meters each. The fabrication work of one span is already over.
The bridge will be placed on four piers of which only one will be erected between the railway lines and three will be away from the railway lines.
