This layout formed the basis of Brodie's wide new boulevards such as Queens Drive and adjoining radial roads such as Menlove Avenue.

The design attracted attention from across the world and he is known to have influenced Grosvenor Atterbury who used a similar technique to build the houses at Forest Hills Gardens.

He visited India twice for this purpose and in 1931 was invited to the official opening ceremony by the viceroy owing to the high regard that Edwin Lutyens, the chief planner had for him.

Brodie worked on this project jointly with engineer Sir Basil Mott and the tunnel was completed in 1934 following nine years in the making.

At the time of its construction it was the world's longest underwater road tunnel, a title it held for 24 years, and remains to this day the UK's largest municipal engineering project.
