Raleigh police say the intersection at Lynn and Lead Mines Roads will probably be closed all day Sunday.
A tree fell there about 10 p.m. Saturday knocking down two utility poles that carried a major power line.
Police say power in the area was restored in fairly short order, but extensive work is required to replace the wire and poles.
Detours are posted.
