ALTERNATIVE NATIONAL ROUTE 1 - Hornsby, NSW
Lifespan: c.1973/74-1989 (15 years)
Northern Terminus: Pacific Hwy & Jersey St North, Asquith
Southern Terminus: Pacific Hwy & George St, Hornsby
Route taken: George St, Bridge Rd, Jersey St North
I did not know this route had existed until recently when I was sent the below photo of an AD sign showing the Alt-1 shield. I am yet to find a map that acknowledges its existance, presumably because of its very short length through Hornsby. My educated guess would be that Alt-1 was commissioned around 1973 or 19744 (when State Routes and Freeway Routes were introduced and not long after NAASRA adopted the guidelines for signing National Routes). I believe it would have survived until the F3 opened in March 1989, although perhaps signage was steadily disappearing as was the case with Alt-1 in Wollongong. State Route 83 now traverses the former route of Alt-1.
