MMRDA Plans Two More Ring Roads Across Mumbai Region
Mumbai’s road authority wants to create two more large driving loops.
Together, the loops would cover about 307 kilometres.
The eighth loop would connect Thane and Navi Mumbai through Sewri and Chirle.
The ninth loop would connect South Mumbai, the western suburbs, Borivali and Thane.
These routes would use some roads that already exist and some that are being built.
The goal is to give long-distance traffic ways to go around crowded inner roads.
Drivers may have to use limited entrances and pay tolls on some sections.
The authority hopes both loops will work fully by 2029, but several connections still need to be completed and designed.
MMRDA plans two additional ring routes covering about 307 kilometres across the Mumbai Metropolitan Region.
The 197-kilometre eighth ring will connect Sewri, Thane, Navi Mumbai and Chirle.
The 110-kilometre ninth ring will link South Mumbai, the western suburbs, Borivali and Thane.
Both access-controlled routes are planned for 80 kmph, with limited entry points and possible tolls.
MMRDA targets 2029, but completion depends on multiple projects, connectors, engineering studies and traffic assessments.
- Who
- The Mumbai Metropolitan Region Development Authority (MMRDA), led on this plan by metropolitan commissioner Sanjay Mukherjee.
- What
- Plans for two additional ring routes totaling about 307 kilometres, expanding the proposed network from seven rings to nine.
- Where
- Across the Mumbai Metropolitan Region, including Mumbai, Thane, Navi Mumbai, Bhiwandi, Borivali and Chirle.
- When
- MMRDA is targeting 2029 for both routes to become fully operational.
- Why
- To provide alternative routes for long-distance traffic and reduce pressure on congested internal roads.
Integrated-network case
Implementation concerns
Traffic and regional connectivity
Integrated-network case
MMRDA says treating Mumbai and the wider MMR as one integrated road network can provide alternative routes, move long-distance traffic away from internal roads and improve connections among Thane, Navi Mumbai, Bhiwandi and freight centres.
Implementation concerns
The routes will not be continuous immediately because they depend on projects that are still under construction or planning.
Infrastructure integration
Integrated-network case
The authority plans ramps, connectors, junction improvements and interchanges where different corridors meet, allowing existing and planned projects to operate as loops.
Implementation concerns
The final connection designs depend on detailed engineering and traffic studies, and the cost of stitching the projects together is still being worked out.
Capacity and access
Integrated-network case
Access-controlled corridors with limited entry and exit points are intended to support faster movement, with a planned design speed of 80 kmph.
Implementation concerns
Several stretches are expected to be tolled, and existing two-lane-per-direction corridors may require widening subject to technical feasibility, available right of way and traffic studies.
Key facts
- Proposed network
- The plan expands the proposed ring-road network from seven routes to nine.
- Combined length
- The two new rings together cover about 307 kilometres.
- Eighth ring
- A 197-kilometre route connecting Sewri, Thane, Navi Mumbai and Chirle.
- Ninth ring
- A 110-kilometre route connecting Nariman Point, Borivali, Thane and eastern corridors back to South Mumbai.
- Design speed
- Both routes are planned as access-controlled corridors with a design speed of 80 kmph.
- Expected operation
- MMRDA is targeting 2029 for both routes to be fully operational.
- Participating agencies
- The network brings together projects developed by MMRDA, BMC, MSRDC and NHAI.
