PORT ALLEN - A crash involving two 18-wheelers on the westbound Mississippi River Bridge caused standstill traffic to back up for miles Tuesday morning. 

The crash happened shortly after 6 a.m. and initially blocked two lanes of traffic on the three-lane bridge. Officials say no injuries were reported. 

As of 10:20 a.m., the wreck was cleared and all lanes were reopened. Delays from the top of the bridge continued back until the I-10/I-12 split. The delay, at its peak, climbed to almost two hours, devastating westbound commuters coming into the city.
