The road connects the city of Mumbai to its suburbs, including the Chhatrapati Shivaji Maharaj International Airport.

Recently another project has been undertaken by the MSRDC to construct a flyover bridge from Vile Parle Onwards to avoid regular traffic jams that occur on the Highway.

The airport flyover, also known as Sahar Elevated Access Road, connects to the WEH using tunnels and bridges.

The other alternative to the SEAR, is to turn east on to local streets which are relatively narrow, have poor lighting and have lower speed limits.

It will have six interchanges with the Yellow, Aqua, Green, Gold and Red line extensions of the Mumbai Metro.
