What to do Saar when frustrations pour over and an outlet is required. Every eve from Mahadevpura to Jayanagar drive is a nightmare. Just on the stretch from Phoenix Market City to KR puram station takes 45 mins or one hour even. Then cross over and the nightmare continues on old madras road. Until one reaches Bypanahalli. Then some relief and the trouble starts on the road leading to the erstwhile Lido theater. Narrow and cratered road.
It can take 2-2.5 hours every eve starting at 8 from Mahadevpura.
Every single Bangalorean here agrees sir, look at my location tag.
Personally I believe the best route for you would be what Bangalorean suggested. Longer route, but equally longer time before Migrane sets in.
But on your regular OM road route, if you know the inner roads from Byapanhalli to Lido, then the travel will be a little longer but far smoother until you reach MG Road.
Anyway, the ORR road is far smoother than before. There is a jam near the first underpass near New Horizon College, but clears eventually because it is only a bottleneck where the three lane road becomes one lane. There is a jam near ECOSPACE. Once the fly over is built, it should not pose a problem. Bellandur jam is pretty ok, survivable. But it is a little congested. The next jam is only at Silkboard, if you don't take Sarjapur road towards St Johns. So, at least a 20Km stretch will be freed once the two flyovers are completed along with the underpass near New Horizon College.
The last I checked the flyover work is "nearly" completed, so the only major jam would be at New Horizon between KR Puram area and Silkboard.
I don't know last when you traveled on ORR, but I hope this helps a little.
