UPDATE: Team en route to fix lines, highway still closed
UPDATE 3.40PM: Police are continuing to stop traffic on the Warrego Highway, but will shortly be opening west-bound lanes to let through banked up traffic.
At present, there are 24 residents recorded without power, in Glenore Grove, Crowley Vale, Plainland and Forest Hillan Energex spokesperson said.
An Energex rapid response unit is en route to the scene to fix the broken powerline.
A witness said a roof from a pantech truck detached itself, hitting the power lines, causing them to fall.

It's expected the power will be restored by 7pm.
