With the subsequent passing of the Main Roads (Amendment) Act of 1929 to provide for additional declarations of State Highways and Trunk Roads, the Department of Main Roads (having succeeded the MRB in 1932) declared Main Road 330 from the intersection with City Road to the intersection with Dowling Street (today South Dowling Street) in Surry Hills on 21 February 1933, and extended east to the intersection with Anzac Parade on 2 December 1964.
