I have been taking my wife to Hosur MGR College since 3 weeks, over the weekend, for her MBA exams.
Road is super for the 42 kms, except for Chandapura and Attibelle (Athipalli) circle entrance and not to forget the junctions of Bommanahalli and Electronics City.
NRN has to do something to speedup the flyovers.
The return travel around 2.30 is a mess at Sparsh, RTO etc. Too much of work is going on. No lane dividers are there and for guys like me used to US roads, it is a mess. These slow moving trucks kill you!
For the same distance and 15 more minutes, you can avoid the messy traffic into South Bangalore and reach Bannerghatta Road, JP Nagar areas by taking a left on the Attibelle Circle and continue straight (dont take left or right) till you reach Anekal (you can visit your farmland, like I do on the way!) and take a right, to reach Bannerghatta via Jigani.
Smooth as Hemamalini cheeks, like Lalu said.
The Saturday morning drive takes 1 hour and 10 minutes in the normal NH7 route, while on Sunday it reduces by 10 minutes and I dont exceed 65 - 70 kmph as my car is new.
The return drive on NH7 is cool too! About 1 hour to reach Mysore Road junction at Silk Board. Then the fun starts of crawling.... on Saturday and while Sunday is cool.
