A woman has been freed from her vehicle after it rolled in Braddon on Thursday morning.

Emergency services were called to the scene of the two car crash on Ainslie Avenue, near Gooreen Street, shortly after 10.40am.

One car had rolled and landed on its side, blocking both lanes of traffic. The roads have since been cleared.

An ESA spokeswoman said the woman had been trapped in the vehicle, but was later freed by ACT Fire & Rescue using hydraulic tools.

She was treated at the scene for minor injuries before being transported to the Canberra Hospital.

Police were also called to an earlier crash in Kambah.

Crews were called to St Thomas Primary School after two cars collided outside the school around 10.15am.

Traffic had been blocked in the area around Barritt Street and Reynell Place, but an ACT Policing spokesman said the roads were now clear.

Ambulance officers were also called to the scene to treat minor injuries.
