Chennai Flyover Projects

[anekho]

Just curious Kannan-ji; if all of us on SSC put our heads together and come up with something good, who do we approach with our proposal/views?

We have done the same a few times with partial success.

I have contacts within the Govt who will be given all these details.

Some of our ideas may be implemented.

Let's start.

[Arul Murugan]

Instead of building multiple flyover, subways introduce more one way system.

It is working good at Nungambakam, Anna Salai Halda Jn etc.,

======================================================

1. Build wide bridges on buckingham canal for free left turns opp to Tidel and at the end of LB road-SRP tools

2. Widen the interior roads of Thiruvanmiyur by Land acquisition

3. Widen the Thiruvanmiyur signal and pull down few buildings for free left

Only big advantage with such oneway system is that, vehicles needs to travel little longer (0.5 to 1KM) distance.

But smooth traffic flow will be ensured for sure!!

[Murali Bala]

Arul very nice plan to implement, it will be a great success, may be it will create some heart burn of folks living there. We should bring such plans to the Media so that we a can open the Arivukan (knowledge eye) of traffic police.

[sshivakumar]

Arul, exactly what I had in mind. Good job putting it on a map, implement this and improve/encourage public transportation and this should definitely ease the situation.

This is a good read if you have time,

+1, like it. only add-on is where there is a crossover with the OMR some simplistic ramp needs to be built even if its just a merge traffic... inspite of the b.canal

[QE]

seems to be a nice idea but, how do ppl from Tidel park go to ECR and ppl from LB road to OMR towards Madhya Kailash - are you proposing a signal at LB road & OMR intersection?

[kannan infratech]

Arul'

As usual, you rock.

Only ECR to LB Road - local people protested and got it cancelled (the scheme) earlier.

Sankara School & other schools and resi area deeply affected along that stretch.

But it can be implemented as a temporary basis till a solution is found.

[kannan infratech]

SRP Tools need a solution as there will be right turns

A small u-turn with signal can be introduced b/w Thiruvanmiyur MRTS station and Indira Nagar MRTS station for the traffic from Tidel park for proceeding to down OMR or ECR.

Also small U-turn with signal can be introduced at existing Tidel signal for MK/SP road traffic to enter Tidel park.

These signals can be clubbed with pedestrian crossing signal.

and ppl from LB road to OMR towards Madhya Kailash - are you proposing a signal at LB road & OMR intersection?

Adyar side LB road traffic to MK have to travel all the way till the south end of LB road via West Avenue road, South avenue road and merge with up coming ECR traffic. 1.5KM extra distance they need to travel.

As Ramvardan and Kannan said, residents in that locality needs to co-operate. But this will surely save crores of man hours, fuel in long run.

Translation:

- The delay in construction of Flyover at 100 feet road in thirumangalam is causing hardships to the public.
- The IRR links 4 major highways in Chennai: The GST road, GNT road, Grand Western trunk road (???) and the chennai - Thiruthani - renigunta highway.
- In this IRR, the traffic density is very high at thirumangalam junction. About 11,639 vehicles cross this junction per hour.
- govt planned a flyover at this junction at a cost of Rs 60 crore 23 lakhs. The foundation stone was laid last year.
- The flyover will be 805 metres long with 21 pillars. There will be 7 metre wide service roads at the sides along with 2 metre wide storm water drains and footpaths. The plans also include a pedestrian subway.
- One year on, works are progressing very slowly. Only 12 out of 21 pillars have been built. Even those are not completed fully.
- works on Storm water drains, foot paths, pedestrian subways etc. have not even started.
- Only 30 workers are working anytime.
- The resulting traffic congestion leads to wastage of petrol.

- there are lakhs of people working in the surrounding areas. There are lots of educational institutions also. This leads to heavy traffic snarls.
- when asked about this, the highway officials said that the contractor has already been fined Rs 1.5 lakhs for the delay. Works will be completed soon.

IMO, even the diversion planning was not good. Police and higways department know very well that the new route is going to be having heavy traffic and the existing road is not good. In that situation before diverting that route has to be prepared to meet the heavy traffic. But none of the diversion happend till now has not met this process. Why traffic police and highways department takes life of every individual for granted. are we not paying any road taxes? I cross this 18th main road and 13th main road in anna nagar and the road is worst like anything.

@Arul - If there is anyway the ppl from tidel park, elnet and soon to be opened Ramanujan IT city can be diverted backside to Taramani road, they can merge into the traffic and take right turn to ECR.

Proposed Traffic Flow at Madhya Kailash Junction

CCTP should allow traffic on the west canal bank road as shown in the picture. This will reduce congestion on the sardar patel road. This arrangement might increase congestion on the gandhi mandapam road but this road has greater capacity than Sardar Patel road. This will also reduce the time required for vehicles to go from Madhya kailash to Gandhi mandapam junction which will in turn reduce congestion in the opposite direction.

Arul, good effort . But I am afraid there are some drawbacks in this proposal.
The main thing is, IT Highway and LB Road are not comparable. One is much wider and LBR esp the last leg (after Jayanthi junction to SRP) is very narrow. So making both one way means a broad 6 lane road is underused while LBRoad stretch gets heavily overloaded. This will fail.
Another problem is U Turns. It will work only for 2wheelers and cars. Consider Buses, big ones. Bus traffic is v.heavy at peak hours. If we have 2 U turns it will take hell lot of time for buses to make turn and lot of road space will get wasted.

Maybe we need to modify this proposal. One idea is - Let IT highway continue to be bidirectional always. LB Road from Jayanthi Signal till where it joins ITHighway can be 1 way. Traffic from ECR gets routed through what you said to SRP Junction. Here let us have a signal that allows this traffic to turn U right into the left lane of IT Highway (i mean the TIDEL park Lane).

Another idea - generic one is - control all bus traffic that originates from MK/Adyar towards Mayajaal and beyond , dont allow them through MK-ITH or ADY-LBR , instead route them througy VLCY and then Pallikaranai, 200 ft road, ITHighway, KK road and finally ECR.

All said, I think we have to somehow have a flyover. One ways wont work beyond a point in this place.

I am afraid you are wrong. Flyovers are called interchanges in US but found in plenty. . Pls search for "Five High interchange" in wiki/google. Amazing structure I say. These are things which are made possible in developed nations, while we still think that kathipara flyover and Mumbai Sea Link are greatest things constructed !!

Having said that, I am also not for flyovers in every corner. But atleast here in TiDEL-Thiruvanmiyur junction, we have no option (unless we expand LB Road, but that is even more costlier). I have traveled extensively in this place and the traffic position is getting worse month after month, year after year. The more we delay flyover, the more is the damage and waste(time,fuel etc)

[Ramki830]

One more point I feel we ignore -whenever a road with HEAVY TRAFFIC is made Oneway, Let us have some pedestrian flyover or some facility for pedestrians. My experience is that any one way arrangement severely hits pedestrians (who are the most neglected/ignored segments of urban society). Esp think of residents of these places, many of them senior citizens ,some have vision and hearing problems.

The Kottur Road is so narrow and is already choked even during normal times.

There was a proposal to construct a bridge across Adyar in continuation of the Canal Bank Road (west side of B Canal) and the road will meet Anna Salai near the YMCA at Nanadanam.

This way the major traffic from Anna Salai can take this route and the traffic jam in IIT signal will be less.

The Interchange at Madya Kailash will have 4 arms one in West Canal Bank Road, One in IT Corridor and two sides of SP Road.

Since there is a canal, subway is ruled out. Since there is a MRTS overhead line, the alignment got shifted towards CLRI and CLRI KV School has refused to give space.

They should have made the IIT fly over 2 way and extended the same over the MRTS line.

They should plan the traffic management of all the nodes from IIT to Malar Hospital and Nandanam to SRP Tools.

Problem is IIT Flyover was planned in 1998-99 while MK-IT Highway came up latter (2003 onwards). I believe that IIT Flyover expansion would run into LA Problems. So alternatives like Highway along adyar river-canal bank road right till MK junction (something like what you said) would be considered but cost may blow up so I don't expect anything in near future.
