Kolkata traffic police on Sunday, April 26, 2026, announced a two-part plan to ease congestion on the Maa Flyover: real-time portable signs that warn drivers about breakdowns ahead, and more openings in the median so tow trucks can reach stranded vehicles faster. The new measures go live Monday on one of the city's busiest elevated corridors.
The Maa Flyover is a key east-west link for the city, and it doesn't take much to turn it into a long parking lot. A single stalled car during peak hours can create stop-and-go conditions for miles. Police say vehicle breakdowns are the main trigger — not rush-hour volume. That's why the new plan focuses on giving drivers earlier warnings and giving recovery crews faster access.
Portable signs at three approach points
Starting Monday, portable variable message signs, or PVMS, will be placed at Circus Avenue, Gopal Mukherjee Road and E M Bypass. These are major feeder routes that lead directly onto the flyover. The boards will show live alerts about road conditions ahead, so drivers can decide whether to get on the elevated corridor or take a different route.
A traffic department officer explained how the messages will work: “Messages like ‘Vehicle breakdown ahead’ will pop up on the screen to alert motorists before they take the flyover. Once the road is free of congestion, the display board will show ‘Road Clear.’”
What makes these signs useful is that they're portable. They can be moved from one spot to another as trouble areas shift with the time of day. A permanent sign is stuck in one place. A portable board can be repositioned to where the next breakdown is likely to happen.
More median cuts for tow trucks
In a parallel move, Kolkata Police has doubled the number of cuts in the median divider on the Maa Flyover from three to six. The openings are meant strictly for tow vehicles. When a car breaks down, a tow truck can now enter from the nearest cut instead of crawling from one end of the flyover.
Deputy commissioner of traffic Sambhav Jain said, “The primary reason behind traffic congestion on Maa flyover is car breakdown.” His team expects the extra openings to shave valuable minutes off response times.
Police have made it clear that regular drivers cannot use these cuts. “The cuts will be sealed with guard rails and will be used only to tow broken-down vehicles. They will not be used for taking U-turns,” an officer said. That matters because unauthorized U-turns on a controlled-access road can cause rear-end crashes and make congestion even worse.
Why real-time warnings make a difference
The concept behind the signs is straightforward: if drivers know there's a stalled truck a few hundred meters ahead, they can exit or reroute before getting trapped. If the road is clear, they don't have to wonder. That reduces sudden braking, last-second lane changes and secondary crashes.
This is not just a Kolkata idea. In the United States, portable changeable message signs are a standard part of incident management. The Federal Highway Administration, through the Manual on Uniform Traffic Control Devices, recognizes these sign boards as a reliable tool for temporary traffic control and emergency response. Drivers in cities like Atlanta, Los Angeles and Dallas see them all the time in work zones and crash cleanup operations.
Kolkata's approach is a lighter and cheaper version of what American agencies call an intelligent transportation system. Instead of installing expensive overhead gantries with cameras and sensors, police are using mobile signs and better physical access for recovery vehicles. It's practical, adjustable and far less costly.
What's still missing
Real-time signs only help if drivers see them early enough. The chosen locations cover the main approaches, but some drivers entering from smaller side streets may miss the alerts. Police have not said whether the same information will appear on mobile navigation apps like Google Maps or local traffic apps.
Another concern is enforcement. Extra median cuts can be tempting for drivers looking for a shortcut. Police say the cuts will be sealed with guard rails, but physical barriers can be pushed open or damaged over time. Regular patrols and clear signage will be needed to keep the openings exclusive to tow crews.
There's also the question of delay information. A simple "Vehicle breakdown ahead" message tells drivers something is wrong, but it doesn't say how long the wait will be. In the U.S. and Europe, more advanced systems combine message boards with real-time travel data so drivers can estimate delays. Kolkata's portable boards are not there yet, but this is a step in that direction.
What happens next
From Monday, drivers on Circus Avenue, Gopal Mukherjee Road and E M Bypass will see the new boards in action. Police are expected to monitor how well they work during morning and evening rush hours. If the system proves effective, the same approach could be extended to other elevated corridors and major intersections across Kolkata.
For regular users of the Maa Flyover, the immediate benefit is simple: fewer surprises. A quick look at a roadside board could save a 20-minute detour. For the traffic department, it's a visible attempt to manage congestion without resorting to long closures or lane bans.
The combination of real-time alerts and faster tow access attacks both sides of the problem. Drivers get better information before they enter the flyover, and police get better access after an incident happens. That two-part strategy is more likely to keep traffic moving than either measure alone.
Bottom line
Kolkata Police is betting that smarter incident management will do more for the Maa Flyover than simply widening the road or adding more lanes. The signs and median cuts are cheap, flexible and aimed at the root cause: disabled vehicles. Whether they fully deliver will depend on execution, but the direction makes sense.
The move also puts Kolkata in step with a global trend toward practical, tech-supported traffic management. U.S. cities have spent decades refining portable message sign deployments. Kolkata is adopting a similar playbook with local tweaks — and doing it quickly.
Drivers should still expect some delays during major incidents. No system can clear a stalled vehicle instantly. But with earlier warnings and quicker tow response, the worst of the Maa Flyover snarls could become less common.
