This will facilitate the vehicles to move for due to less traffic and connects one side to ORR service road and another to other side of the road after changing the direction. Graphite India Road. Between the two elevated roads is 6 m lanes at the ground level exists which was The existing traffic along Goshala road is manageable due to low volume and planned earlier for BRT system. Due to many reason BRTs is shelved and instead of hence road is not divided in spite the width can accommodate (2+2) lanes. that an elevated road with two tier mode of transportation covering 10-lanes is Since the road connects to two busy roads namely Outer Ring Road as well as proposed. graphite India road, thee two roads are proposed for various traffic management In addition to this Government understood the strong need for mass transportation schemes as well as widening etc. system and accordingly metro link is coming up connecting Marathahalliside metro Presently all type of vehicles except buses will move on this road and this acts as a to ITPL and as well as Biyappanahalli. link road connectingORR to Graphite India Road. The overall RoW includes CW of 6 m for BRT, (8+8) m SR, (6.5+6.5) m area ORR is having ROW 45 m, (2+2) SR lanes divided road which connects to separator on either side, (3+3) m FCD on either side of the road. Marathahalli on one side and K R Puram on other side of the road. The project can also be accessed from other places such as The trough traffic will move over the Flyover and connected to the ground level at Marathahalli, HAL, Kadubisanahalli, Bellandur,Panathur,K R Puram etc. many places for the convince of local traffic to join or exit from the elevated portion.
