Mumbai's Reay Road cable-stayed bridge approaches completion

06 Mar 2024 CW Team

It was reported by officials that all foundation work for the Reay Road project, a vital east-west connector, has been completed. Currently, the girder launching and superstructure work are in progress, indicating a 70 per cent completion of the ROB. Officials are anticipating the entire project to be concluded by May 2024, provided that all right of way (ROW) is cleared.

In an effort to minimise disruptions to the city's busy traffic, MRIDC has adopted a strategic approach, planning to construct a new cable-stayed bridge adjacent to the existing one and subsequently demolish the old structure. This plan aims to ensure minimal hindrance to both vehicular and pedestrian movement during the construction phase.

Commencing on February 14, 2022, the construction effort has involved the relocation of 156 structures, including 130 hutments, 15 shops, and one ticket booking counter. The relocation of 130 structures has been completed so far. However, the remaining structures, consisting of one ticket counter and 15 sheds, are set to be relocated by Mumbai Port Trust (MbPT) and Central Railway.

According to MRIDC, the Reay Road ROB has a center pylon system where stay cables are erected on the central spine girder of the bridge. MahaRail has designed the cable-stayed ROB with limited piers and less foundation, with the help of cables.

An official stated, The construction scheme has been chosen to be segmental construction, which helps for better quality control and minimum construction time. The individual segments are prefabricated at the fabrication yard and transported to the site for erection. For the straight alignment, a simple steel girder system is adopted for easy and speedy construction.

The new cable-stayed ROB, with a longer span, minimiss infringements with underground utilities, according to an official. It will have six lanes with a footpath for pedestrians, ensuring smooth traffic.

The bridge structures will allow traffic movement through the underpass of Barrister Nath Pai Road and also maintain the required vertical clearance for the passing of vehicles under Eastern Freeway as per Indian Roads Congress (IRC) standard. Additionally, MRIDC has designed architectural LED lightings on the proposed bridge, which will enhance the aesthetic appeal and also have designed to improve the safety parameters with the bridge monitoring system, the official added.

The Maharashtra Rail Infrastructure Development Corporation (MRIDC), known as MahaRail, has been assigned by the BMC to undertake the reconstruction of ten deteriorated British-era road overbridges (ROB), including the crucial Reay Road cable-stayed bridge.
