Bombay Bypass - North

HOW TO BYPASS BOMBAY via New Bombay - North side
On NH8, 55 kms from Manor you reach Ghodbunder. This point is 28 kms after the toll gate.
The indication that you have reached Ghodbunder is:
Left is Thane 20 kms, Straight is Dahisar 8 kms, Borivli/Bombay. You will see
Hotel Fountain at the junction. You reach Ghodbunder immediately after crossing the 1/4 km long River Ulhas bridge.
Before you reach Ghodbunder, you will see a few signboards pointing to Thane/New Bombay/Pune, etc.
Please DO NOT take any of those turns, take the left turn only at Ghodbunder. TURN LEFT and Continue on the road from Ghodbunder to Thane (you will cross a toll gate 200 mtrs into the road). Road is double road all the way.
You will shortly cross a ghat, and then come down to a place where the road runs parallel to the Ulhas River (to your left).
You will start seeing several buildings and restaurants on both sides of the roads as you start approaching Thane.
You will cross a few junctions
flyovers and you may experience some minor jams depending on time of the day.
You will cross the Hyper City (right side of the road) and R-Mall (left side).
At the end of 15 kms form Ghodbunder, you will hit Majiwade, the first messy junction (round), also a flyover partly under construction.
Just before reaching that junction, you will see on your left a large building with Vihang’s signboard, Vijay Sales showroom, Fiat dealership and on the right side the Cinemax Multiples/Mall. 

After crossing this small round (road very congested at this point) (you will see
Big Bazaar to your left), you will reach another confusing junction (with a flyover going across - left to right and another flyover curving to the right above). There are 3 roads here at this junction - immediately left turn is Nasik road, immediate straight  is going into Thane city, and right (along with the curve of the right side flyover) is your route (the road to Bombay). You will see a board saying Pune to your left -  please DO NOT take that road. TURN RIGHT at this flyover junction.
Once you are beyond the flyover, keep going straight. Immediately after this junction, you will have another flyover which you must take - this flyover is 1.5 kms long, almost an elevated road (you will see ITC Fortune Hotel & Jupiter Hospital to your right and Hotel Lerida to your left). After coming down the flyover, the road naturally curves to left and you will see another flyover - take that also - this one is a 1-junction small flyover.
Keep going and you will reach Bombay octroi naka/ check post -  landmark is a large Fort-type gate across the road, lorries all over the place and some muddy boards saying Bombay - Gateway to India.
After the octroi gate, within 1/2 km, you will cross the toll gate (Rs 30 toll), and after that a flyover (this is Mulund).

Within 1 km, you come to
another flyover - DO NOT go on this flyover, go below and turn to the left  (sign boards saying Mulund-Airoli Bridge, Airoli, New Bombay, etc, right goes to Mulund). TURN LEFT and after crossing a check post again, you will reach another toll gate (Rs 30 toll). After the toll gate, you will cross the Thane Creek (backwaters) (1.5  km bridge). At the other end, you reach Airoli in New Bombay.

After crossing the bridge, you cross a round and a signal, followed by a dip down to a subway in a T-Junction.
Turn RIGHT towards Pune (left goes to Thane, right to Kopar Khairne, Turbhe, Vashi, Pune).

This is also a double road - this is the
Thane-Belapur road and you will see industrial units all over. The most prominent complex will be the Dhirubhai Ambani Knowledge City (DAKC Complex) to your left. You will also see a Shell petrol pump. There will be several flyovers, most of them pedestrian crossings. But AVOID 2 flyovers which curve to the Right (they go to Vashi). There are signboards marked for Pune before every flyover.
You will go around 10 kms on this road - you will see Kopar Khairne local railway station to your right (opposite Reliance) and after that the Turbhe railway station (Turbhe is a slum-type place).

Within 1/4 km after you cross Turbhe railway station, you will see another flyover (right going to Vashi) - keep going under it.
You have reached the main 
Bombay-Pune road. After Turbhe, keep going - Nerul, Belpaur (CBD, Konkan Bhavan, Park Hotel to your right) and Kalamboli which is where the Expressway to Pune starts - around 15/20 kms from Turbhe.
Ghodbunder-Thane, 15 kms
Thane-Airoli, 13 kms
Airoli-Turbhe, 10 kms
Time estimate: 1.5 hours from Ghodbunder to Expressway
