The cost of the Mrinaltai Gore flyover expansion project in Goregaon, Mumbai, has increased by about Rs 38 crore. While the initial cost was Rs 209 crore, it has now reached Rs 248 crore.
Work in final stage
The work of this flyover, which is being constructed on S. V. Road between Ram Mandir Road and Relief Road, is currently in the final stage. The flyover is likely to be opened for traffic next month.
After the flyover is opened, traffic congestion will reduce and connectivity between Ram Mandir Road and Goregaon West will improve.
Project background and expansion
The first phase of the Mrinaltai Gore flyover was completed in 2016 at a cost of Rs 255 crore.
The land acquisition for this project was done through the Mumbai Metropolitan Region Development Authority (MMRDA), while the construction had started by the BMC since 2009.
After the first phase, the work of expanding the flyover from Ram Mandir Road to Relief Road on S. V. Road was taken up. The actual construction of this expansion began in March 2019.
The flyover is considered an important corridor for traffic as it passes through highly congested intersections.
Execution of work
The project is being implemented by a joint venture MEPL-Gyan.
Structural challenges and cost escalation
Keeping in mind the space constraints and the need for quick completion of the work, MS structural steel was used in the superstructure of the flyover. Important underground utilities like water supply pipelines, cables and drainage system were shifted during construction.
Since the bridge passes over the Walbhat river on Ram Mandir Road and the Oshiwara river along S. V. Road, there was a high risk of corrosion due to water and tides. Hence, stainless steel girders were installed on both the rivers to enhance durability.
Also, the old 900 mm diameter sewage pipeline was replaced and other structural improvements were made. All these works have increased the cost of the project.
