In 1937, work had progressed on extending Berwick Street eastwards, and it had been extended to Alday Street by November 1938. A new causeway to extend Berwick Street north over the Swan River, and make it a truck route, was considered by the state government in 1940. The existing Causeway, from which Albany Road commenced, had experienced almost a doubling of traffic volume between 1930 and 1939. However, the new Causeway was eventually constructed adjacent to old Causeway, which was then demolished.
