A long traffic back up on I-80 eastbound west of the metro.  An accident at mile marker 434 near Gretna brought traffic to a standstill Monday afternoon.  There are reports that two vehicles collided around 4:15 pm.  One lane of traffic reopened around 5 pm and all lanes were open about 20 minutes later.  

Due to the backup the wait to get through was estimated at 30 minutes at 5:30 pm. 

Details about what happened are not available.
