Feasibility Report and Detailed Project Report for Planning and Construction of a Grade Separator Connecting Anna Salai and Mahalingapuram through Usman Road suitably integrating existing Flyovers in the route for Chennai Corporation
Falls in Zone IX,X,XIII of CoC
Length - 3.5km in busy shopping area
9 Major junctions
Grade separators at 2 junctions at 800m apart
Project Corridor (Usman Road)
2
Below T.Nagar Flyover Near Habibullah Road Jn
South Usman Road Siva Vishnu temple
Alternatives – Elevated Corridor from Anna Salai to Mahalingapuram
3
Alt. Description Status
1-6 Elevated Continuous/Discontinuous corridor from Anna Salai to Mahalingapuram
Not feasible
7 Extension of Usman Road Flyover on Southern side covering Burkit Road Junction
Under consideration
8 Elevated 2 Lane Corridor between Boag Road junction and beyond Bazullah Road junction ending before Mahalingapuram Flyover (Disturbing both northern and southern approach of Usman Road Flyover)
Under consideration
9 Elevated 2 Lane Corridor between Boag Road junction and beyond Bazullah Road junction ending before Mahalingapuram Flyover (Disturbing only southern approach of Usman Road Flyover)
Under consideration
Pedestrian Zone - Madley road Jn. to Duraisamy road Jn.
4
• Heavy pedestrian movements along the corridor - 4000 to 6000
• Heavy pedestrian crossings at Bus stand, Ranganathan street jn. , Duraisamy road jn.
• Proposed for “Pedestrian Zone”
• Pedestrian subway across Madley road and Duraisamy road
Alternative 7 Extension of Usman Road Flyover Covering Burkit Road Junction
5
Item Details
Length & Width 1.5 km & 10m
Total Project Cost INR 260 Crores
EIRR (base case) 19%
• Extension of Usman Road Flyover covering Burkit road junction
• Eliminates major pedestrian - Vehicle conflict at Ranganathan street junction and near T.Nagar bus terminus
• Facilitates free flow of about 4000 pedestrians during peak hour from Pedestrian zone to the railway station and bus stand & vice versa
• 50% of traffic flowing at- grade will use the flyover
• North bound MTC buses have to take a detour using Boag road and Muthurangan road to enter and exit from Bus stand
• Involves reconstruction of southern side of approach ramp of Usman
road flyover
Alternative-7
6 L-Section
7
• Extension of Usman Road Flyover on both approaches with 5.5m clearance to create hassle free shopping environment
• Eliminates major pedestrian - Vehicle conflict at Ranganathan street junction and near T.Nagar bus terminus
• Free flow of about 4000 pedestrians during peak hour from Pedestrian zone to the railway station and T Nagar bus stand & vice versa
• 35% of N-S straight traffic flowing at- grade will use the flyover
• Part of through & North bound buses will be benefited with flyover & few bus routes needs to be diverted
• Involves reconstruction of both approach ramps of Usman road
flyover for integration with the proposed flyover
Alternative 8
Elevated continuous 2 Lane Corridor of 10m carriageway between Boag Road junction and beyond Bazullah Road junction ending before Mahalingapuram Flyover (Disturbing both approach ramps of Usman Road Flyover)
Item Details
Length & Width 2.2 km & 10m
Total Project Cost INR 384 Crores
EIRR (base case) 12%
Alternative-8
8 L-Section
9
Alternative 9
Elevated continuous 2 Lane Corridor of 10m carriageway between Boag Road junction and beyond Bazullah Road junction ending before Mahalingapuram Flyover (Disturbing only southern approach ramp of Usman Road Flyover)
Extension of only Southern Side of Usman Road Flyover
with 5.5m clearance + Isolated flyover across Bazulla road
Involves reconstruction of only southern approach ramp
of Usman road flyover for integration with the proposed
flyover
The other features & benefits are same as Alternative 8
Item Details
Length & Width 2.2 km & 10m
