NHAI is using a combination of a flyover, rotaries and ramps on the NH 275 and ORR to mitigate the conflict points at the main junction.
The new design serves as a no frill interchange replacing the earlier proposed clover leaf and 3 tier rotary system, both now dropped for lack of funds and space.
Exchange of traffic between NH 275 service roads & Main carriageway
NHAI has designed a rotary-ramps concept on the Mysuru-Bengaluru NH 275 Highway which will ensure easy movement of vehicles between the Service roads & the Main carriageway.
As seen in the concept below there is a grade rotary on either side of the highway flanked by entry & exit ramps connecting the main carriageway. The traffic will move in clockwise direction around the grade rotaries while the ramps will have anticlockwise circulation.
The concept is self explanatory, and the reader is requested to follow the arrows marked to understand the traffic interchange paths.
This system is proposed to come up on NH275 slightly ahead of the Water Aqueduct as seen in the Flyover GAD.
14.5M +14.5M +4M (Median) wide 225 M long Flyover will cater to the NH 275 main carriageway traffic entering & exiting the city.
At the junction a big roundabout/ rotary will channelise the ORR & NH 275 service lane traffic smoothly.
A vehicular underpass will be built to provide Entry & Exit to Bannimantap road from the service lanes.
Plz share it original sketches in a zip file , atleast share its tender location
