road widening near airport is most welcome.

Have to drive carefully by using mirrors properly

The problem is lane discipline and speed. Nobody follows that in India. The problem with that particular curve is, before the flyover, there is the aazargana curve which has 5 lanes towards guindy. Therefore everybody is used to driving fast in that bend before taking the flyover. So after you get onto the main arm, you are always supposed to reduce the speed while taking ramps such as the clover leafs and maintain the proper lanes. Also the actual width of the curve is only two lanes with 2 feet of shoulder width on either side. I dunno why the hell that was made a 3 lane ramp. Never have I seen such a 3 lane curve with such a small turning radius.

Will this Pallavaram - Kunrathur Rd Flyover come up on the GST road? Will this be a single flyover like the one near Airport or a rotary enabling people to move into the Kunrathur road.

Either ways, It'll be the 3rd flyover within a very short distance - between Pallavaram and Chromepet flyovers. And if you consider the Tambaram and Airport flyovers, then there are 5 flyovers.

GST road is becoming a road of flyovers starting from Kathipara
1. Kathipara
2. airport Flyover
3. Pallavaram Flyover
4. Pallavaram - Kunrathur Flyover (Proposed)
5. Chromepet flyover
6. Tamabaram Flyover
7. Flyover at Chennai Bypass
8. Perungalathur Flyover (Proposed)
9. Vandalur Flyover
10. Flyover / Interchange for ORR (under construction)
11. Singaperumal Kovil Flyover (Under Construction)

And apart from this, there are flyovers / subways leading to this road and ending just before the road - meenambakkam subway, Pallavaram Darga road subway, Tambaram Sanatorium Flyover, Urapakkam Flyover etc.

And looking at traffic explosion after Tambaram, it wouldn't be surprising if flyovers are proposed near places like Guduvanchery bus stand etc.

On top if it, there are metro pillars, monorail pillars ...

Whats the point in subways when the bottleneck is near the Perungalathur railway crossing? Until then we can take a Maduravoyil to Perungalathur bypass avoiding the various flyovers and i dont see that stretch having much traffic except for a brief period before the tollway in that road.

And secondly while coming into the city at Guindy side of the stretch, there is a big time traffic going inch by inch between Jyothi theater Guindy and Ekkaduthangal and then again at Kasi theater and then again at Ashok Pillar and then Vadapalani and last but not the least near Koyambedu busstand. What are the use of the flyovers with respect to this direction?

Regarding the Jyothi theatre - Ashok Pillar stretch, the jam is mainly due to Metro construction. Once the barricades are removed, it will ease to a certain extent. The main bottlenecks there, are two signals - one immedately after Kathipara and the other immediately after Kasi theatre. In both cases, they should prohibit right turns in to IRR and instead, let vehicles turn left and take U-turn either under Kathipara, under adayar river bridge or near K.K.Nagar RTO office. A dedicated U-Turn like the one opposite Raj bhavan will help.

I too feel that there are too many flyover in this stretch. Yet there are also signals all along the place, hampering traffic.

One other main reason for blocks is the absence of a dedicated right turn lane near the signals. Many times, we travel on the lane next to the median and suddenly a signal looms. All vehicles waiting to turn right just occupy the median lane and we're stuck behind them or have to carefully move into the center lane. It is a very difficult situation in GST road.

[PrinceRaj]

Cant guess how the flyovers (2) are going to come at vijayanagar ... there is hardly any space for construction of pillars ...

Anyway since 98 crores allocated probably going to kick off soon

If they expand the Pallikaranai-medavakam road and make it 6 way then vehicles can avoid GST Road

[natarajan1986]

I felt that gemini flyover loop to nungambakkam should have speed breaker before entering that loop and after 30 mts another two speed breakers.when i drive my bike at 40kmph ,and i just reduce it to 30 and take that loop and i slant to turn that loop without reducing speed and i felt speed breaker is must there

[lordvijay]

bad idea, i definitely wouldn't want a speed breaker when I'm leaning into a turn that too on one that goes downhill. It ll definitely cause panic to road users.

[kannan infratech]

Speed Breaker may add to the already existing woes.

Wider and broader curved loop will help.

[lordvijay]

The one flaw if you can call it, on the Gemini flyover maybe the loop to Nungambakkam, I feel the loop should have been aligned to get straight on to the perpendicular road, instead of an additional S bend.

loop to nungambakkam is what the whole topic is about my lord. confirmed it is a flaw

[proprashanth]

yea that loop is really bad... it's difficult even for cars at low speeds.

[krishnancv]

The loop should be made larger with a natural banking inwards. Maybe a 5% gradient. Then vehicles can ply safely. That's same issue with Kathipara flyover too. There is no banking in the loops.

[Vicvin86]

Instead of digging up graves of engineers who build it, it is better to drive a little slow.

[krishnancv]

we don't need to blast the past. But we can definitely repair gemini loop as it rests on ground and is not supported by beams. On war footing(which necessary because of its importance) it could be completed within 40 days.

how about restricting heavy vehicles until they repair it. might work

[lordvijay]

Dunno if it would be feasible at the moment, already metro construction is slowing the traffic. Diversions/restrictions would be confusing and frustrating.

[sshivakumar]

Guys, agreed that the design of the loop is not correct and lots can be improved.. blah.. blah..blah. But lets remember that its not the only reason, after all the same buses have been plying in that route for 39 years now.. how many accidents have we seen?

I think it is easy for now to fix the buses (as per the reports, the bus was poorly maintained and the driver was overspeeding) and I am sure after this accident everyone is going to slow down in that loop.
