Wreck that dumped nails on Phoenix freeway snarls traffic

PHOENIX (AP) - Part of a Phoenix freeway was shut down for nearly two hours during the Wednesday morning commute after a wreck involving a SUV pulling a work trailer dumped nails and other debris on the roadway. Traffic backed up several miles while northbound I-17 in northwest Phoenix was closed for about 1 mile, forcing traffic to get off the freeway and before getting back on at the next interchange.
