General Information:

B100 is a rural route on the Eyre Peninsula, linking several port, farming and industrial towns with the Eyre Hwy (A1).

Flinders Highway:

The Flinders Highway connects Port Lincoln with Ceduna, via the west coast of the Eyre Peninsula, travelling in a generally northwesterly direction. The highway is named after the explorer Matthew Flinders, who explored this area during the early 19th century.

History:

February 1978: An old road plough was placed beside the Flinders Highway to mark the sealing of the last stretch of highway between Talia and Streaky Bay, on Eyre Peninsula. The then Transport Minister, Mr Geoff Virgo, officially opened the Highway. 2
1998: ALT-NR1 switched to B100 in the change to alphanumeric route numbering, however many ALT-NR1 signs remained along the route.
March 2003: Roundabout at the corner of Lincoln Hwy (A1), Flinders Hwy (A1 and unnumbered), Light St and Hallett Pl in Port Lincoln resurfaced. 3
