The current connectors from the Western Suburbs to the proposed NMIA are the following:
a. From Kandivali, Borivali, Dahisar and further northwards: Ghodbunder Road to Thane and then the Thane-Belapur Road all the way down to NMIA
b. From Malad to Jogeshwari: Jogeshwari Vikhroli Link Road (JVLR) to Eastern Express Highway at Kanjurmarg and then via Airoli Bridge to Thane Belapur Road all the way down to NMIA
c. CSIA via Saki Naka, Ghatkopar, Ghatkopar-Mankhurd Link Road to Sion Panvel Road, Palm Beach Marg, Belapur, NMA
d. CSIA via Western Express Highway, Santa Cruz Chembur Link Road (SCLR), Ghatkopar Mankhurd Link Road to Sion Panvel Road, Palm Beach Marg, Belapur, NMIA
e. Bandra to Kalina via BKC and joining the SCLR and then further on
f. Bandra to Sion and then along the Sion Panvel Highway/Palm Beach Marg, Belapur to NMIA
In all the above cases, the flight time from BOM to any place in India would be longer that the road trip to get to NMIA with the flyover constructions/Metro work underway.
However as another poster has mentioned, NMIA will be attractive to all of Navi Mumbai (pop 1.2 million), Thane (pop 1.9 million) and the Kalyan-Dombivali belt (pop 1.3 million). A lot of Navi Mumbai and Thane residents can be called mass affluent and already are frequent air travelers.
^^@chinmay17shetye, binayak and avier,
I'll admit, haven't been to BOM in a while so don't know how the traffic has deteriorated but i was under the impression that there are connectors like the one through BKC that bypasses WEH and exits out at Mankhurd. Isn't there also Goregaon/Jogeshwari - Airoli link road?
Just to be clear, I am talking about a bus service dedicated from specific points in the city to the airport at a certain (30 minute) schedule like the one they have/had in HYD (not sure if it's still around)
