New post on http://twitter.com/caltransdist3 : Southbound I-5 from I-80 to just north of J Street will be closed at approximately 8 pm. ALL LANES WILL BE CLOSED! This closure is expected to last 2-3 hours as we deal with the big rig that was hauling ethanol that crashed earlier today. Use alternate routes!! CaltransDist3 http://pic.twitter.com/KWbzsggsV0
