A tractor-trailer snagged power lines and pulled down a pole across a Southside road Wednesday afternoon.
Northbound lanes in the 6500 block of Powers Avenue were closed immediately following the accident, which happened just before 3 p.m.
One lane reopened a short time later.
A southbound lane was also expected to be closed for at least an hour.
At one point, there were about 3,000 JEA customers without power.
