DAVIE, Fla. -

All northbound lanes of the Florida Turnpike are reopened after a truck that went over the guardrail was towed away.

It's unclear what caused the truck to end up going over the concrete guardrail before 6:45 a.m. Northbound traffic was backed up for miles as a result. All lanes were reopened by 8:40 a.m. 

The truck was towed away and workers were sent out to fix the broken concrete.

For several hours, traffic was redirected onto a temporary access road in order to get around the truck.
