Lane Cove Road is the main access road from the central and southern suburbs of Sydney to the North Ryde/Macquarie Park commercial and industrial area, carrying a large volume of traffic and becoming very congested during morning and afternoon/evening peak hour.

The Broadway, on the other side of De Burghs Bridge, was officially re-named Ryde Road on 27 February 1952.

[6] The De Burghs Bridge was upgraded to two large high-level multi-lane separate concrete bridges over the Lane Cove River, built alongside each other and replacing the ricketty wooden structure and winding approaches, opening on 15 December 1967.

[7] The intersection with Epping Road at North Ryde was re-constructed into a grade-separated interchange in 1978.

[8] With the conversion to the newer alphanumeric system in 2013, Metroad 3 was replaced by route A3.
