A Lewiston police officer pushes on the tire of an overturned U.S. Postal Service truck with his foot Wednesday before the truck was righted at Ash and Horton streets. The truck flipped when it was struck by a minivan. The driver of the van was attempting to cross Ash from Horton and did not see the mail truck, police at the scene said. There we no injuries. Police did not immediately release the names of those involved.
