Gang,
Thanks a lot for your help and adequate information on the GOA-Bangalore route. Came back last night.
Took Bangalore-Tumkur-sirsi-mirjan-ankola-karwar-goa. Around 640 km. As rightly mentioned by kaushik few bad strected in NH4 and mirjan to ankola and then around Concana.
I took around 13 hours to reach with 1 hour break. Overall the drive was not that bad as expected. Though got stuck in traffic last night before yeshwantpur for 1 hour
.
I would suggest , if someone can start around 3 am in morning then Panjim can be reached easily by 4.00 pm and you will have a peaceful drive with very less traffic.
From Goa preferrebly start around 7.00 am and hit chitradurga road before evening to avoid the bad strectes.
Overall GOA trip was good, let's hope NH4 become little better for a pleasant drive
