Police activity on the Hoover Dam Bypass Bridge temporarily shut traffic down in the area Wednesday, Las Vegas police said.
Police were called to the area just after 10:30 a.m., Metropolitan Police Department spokesman Larry Hadfield said. Multiple law enforcement agencies were called to the area to help, he said.
By 1:30 p.m., the southbound lanes of the bridge had reopened. The northbound lanes were expected to reopen shortly after that once emergency vehicles were cleared from the scene.
