A cyclist has been flown to hospital with what are believed to be serious injuries after a collision with a car this morning at Waterfall in Sydney's south.
The 35-year-old woman was riding along McKell Avenue when she was in a collision with a car travelling in the opposite direction at about 7:15am, according to police.
Police closed the Princes Highway and McKell Avenue in both directions at 7:41am to allow a rescue helicopter to land, and motorists had to queue for about 30 minutes with no detours in place, before the highway was reopened.
McKell Avenue remained closed until 10:07am for crash investigation and clean-up.
It is believed the driver stopped after the collision and inquiries into the incident are continuing.
A crime scene has been established, as standard procedure, and a police spokesperson said inquiries will depend on interviewing the cyclist when her condition improves.
