Inception report Submitted & Approved

Traffic surveys

Submitted & Approved. It is observed that the project Corridor has reached it maximum capacity and additional lanes are required immediately.As there is a restriction in the available ROW, a full length elevated corridor, to increase the no. of lanes, is the solution.

Project Location

Proj

ect R

oad

Poonamalle Road

Kaliamman Street

Chennai City -TAMILNADU State

Study Corridor

1. Link Road Connecting Kaliamman Street to Poonamalle Road via Nerkundram Road in Chennai.


Existing Alignment

Project Road: Starting at Kaliamman Koil Street and Ends at Poonamalle Highway


Background1. Lack of uniform corridor width, 2. Road encroachments.3. Road side Parking/halting/stopping.4. IPT Mode Prevalent.5. Lack of Designated and regulated

Parking6. Lack of pedestrian facilities and city

drainage.7. Lack of comprehensive Management

Schemes.


Issues in the Project Corridor

1. Large number of commercial establishments and substantial number of residential building.

2. There are a number of sharp curves needed to be improved.

3. There are public amenities like Children Park, Hospitals, Cremation Ground and Religious structures

4. Road width is insufficient to the cater the traffic

5. Connectivity of the Link Road


Objectives

1. Improving operational efficiency2. Remove Bottlenecks3. No/min Disturbance to road side

properties4. Mobility for all – Pedestrian, NMT and

2 wheeler.5. Lane space Utilization – Flyover Vs. At

Grade6. Assurance of traffic flow during

construction.7. Economy & Aesthetics


MOST FEASIBILE ALIGNMENTS


Alignment: 1AThis alignment is proposed on the existing alignment with minor changes in the existing curves and with following realignments:• Realignment from ch.740 to ch.1080 (to avoid the

serpentine stretch) and • After Ch. 1870 of project roadThe total length of the Proposal is 2045 m

1870


Alignment: 1BThis alignment starts at the Kaliamman koil Street-Project Road junction and follows the existing alignment upto Chainage 1170 and then passes through open land along the Metro Depot and finally meets the Poonamalle High Road.The total length of the proposal is about 1770 m


Alignment: 2AThis alignment takes off from Kaliamman koil Street-market Road Junction and follows the Market Road upto chainage 1375 and then realigns at the project road upto chainage 1870 and the follows the Alternative 1A upto Poonamalle. Steep curves and serpentine stretch have been avoided.

1870


Alignment: 2BThis alignment takes off from Kaliamman koil Street-market Road Junction and then follows alternative 1B as it passes through open land along the Metro Depot and finally meets at Poonamalle.The total length of the alignment is 1753m


PROPOSAL


Proposal: 4 lane Elevated Flyover over Alignment

1870 Proposed

Cross section


1. In this proposal 4-lane elevated corridor takes off from Kaliamman koil Street-market Road Junction and then follows alternative 2B as it passes through open land along the Metro Depot and finally meets at Poonamalle.

2. Total estimated cost of construction for 4-lane flyover is Rs. 1,72,39,58,544.

3. The total length of the alignment is 1753m

Parameters Governing the Proposal


Merits & Demerits

Merits1. It is smaller in Length as compared to other

proposals.2. Land Acquisition will be least.3. 4-lane elevated corridor to ease the traffic

congestion4. Market road will be utilized.

Demerits5. Cost of the proposal is highest6. Integration with existing alignment is not possible


Comments of Feasibility Report


Points to be addressed as per Minutes of Meeting1. The consultants were requested to study both at-

grade and elevated proposal for the selected option.

2. The consultants were requested to segregate the area details of land acquisition and structures to be affected due to L.A.

3. The consultant was requested to study the proposal of Highways Department in the Kalliamman Street in conjunction with the proposed proposal.


Points 1: At-grade vs Elevated proposal

• The alignment passes through boundary of church and if we go at grade it will require larger area at ground and demolition of structures in the church area will become unavoidable. Whereas if we go elevated, demolition may be avoided by options various pier position.

• The alignment passes through the built up area and hence at grade may increase the demolition which may be avoided in case of elevated proposal.


Points 2: Land acquisition & Structures affected

• ROW proposed: 20 m• Total Area Required: 17500 sqm (Lump sump)• Total no. of structures affected: 19


Points 3: Proposal of Highways Department in conjunction with the proposed proposal.

As per the data collected and information obtained no such proposal are in conjunction with the proposed proposal.


• Proposal though being highest on cost requires least land acquisition and solves the problem of traffic congestion to the maximum

• Based on economic benefits in terms of savings in VOC and savings in travel time cost for passenger and goods vehicles of all the alternatives Proposal 5 is recommendate.

• An economic internal rate of return of 27.17% (more than 12% of discounted rate) and positive value of INR 19,777.30 Lacs as NPV of net benefits indicates the economic viability of project road for the proposed improvement of proposal 5 i.e. 4 lane elevated corridor.
