The Mumbai Metropolitan Region Development Authority (MMRDA) on Tuesday clarified concerns over the design of a flyover under construction in Mira Road, stating that the transition from four lanes to two lanes is a planned feature and not a structural or design flaw.
In an official statement, the MMRDA said the flyover has been designed keeping in mind existing road-width constraints and long-term network planning. The authority refuted claims that the structure “suddenly narrows,” explaining that the present configuration reflects phased connectivity planned for the Mira–Bhayander region.
The flyover does not “suddenly narrow.” The transition from 4 lanes to 2 lanes is not a design flaw, but is based on available road width constraints, and future network planning.

As per planning, the flyover has been designed with two lanes for Bhayander East and future… https://t.co/hZrsBl9SAR
Phased connectivity planned for Bhayander East and West
According to the MMRDA, the flyover has been designed with two lanes for Bhayander East and provision for two additional lanes towards Bhayander West. As the Bhayander East arm appears first along the alignment, the current four-lane stretch transitions into two lanes. The remaining two outer lanes are proposed as part of a future extension across the Western Railway line towards Bhayander West.
Golden Nest Circle section built with 2+2 lanes and slip roads
Up to Golden Nest Circle—one of the busiest junctions in the area where five major roads converge—the flyover has been constructed with a 2+2 lane configuration. This section is integrated with the Metro corridor and includes slip roads on both sides to facilitate effective traffic dispersal amid high vehicular volumes.
Right-of-way constraints lead to 1+1 lane design ahead
Beyond the junction, towards Bhayander East, the available right-of-way reduces as per the Development Plan (DP). Consequently, a 1+1 lane flyover with dedicated upward and downward ramps has been constructed along the median to ensure uninterrupted traffic flow towards Railway Phatak Road, the authority said.
Future widening and safety measures planned
The MMRDA maintained that the design allows for smoother movement across one of the most congested intersections in the Mira–Bhayander belt while addressing on-ground spatial constraints.
Provision has also been made for future widening of the flyover. The authority said the outer sides of both carriageways are planned to be extended by an additional 1+1 lane to strengthen east–west traffic continuity. This proposal is currently at the planning stage and will be taken up in coordination with the Mira-Bhayander Municipal Corporation (MBMC) after securing approvals from the competent authorities.
At present, the flyover is primarily aimed at reducing congestion and improving traffic dispersal in the region. The MMRDA said multiple safety measures have been incorporated, including rumble strips, delineators, adequate signage, retro-reflective tags, directional boards and anti-crash barriers.
The authority added that guidance from traffic police is being actively sought to assess any additional vehicular safety measures before the flyover is opened for public use.
