Higginson Highway in KwaZulu-Natal also known as "Highway Sheila" has an urban legend:-
A woman had a flat tyre waved down passersby who where the unsavory kind, after raping her, slit her throat!
Now whether event happened on the N2 or Higginson Highway this became known as "Highway Sheila" where some have said they saw the woman, offered her a lift she gets into the vehicle then mysteriously disappears.
This story is still told by Chatsworth residents a village not too far from where I live, along the same freeway we use to Durban.
Fact or fiction your decision, or those who have seen her along the road here.
