Authorities reopened Long Beach Boulevard after it was closed in both directions for nearly four hours this afternoon after authorities responded to reports of a suspicious device.

The Los Angeles County Sheriffs Department bomb squad rendered the device safe, and the thoroughfare between Willow and Hill streets was reopened at about 7:10 p.m., the Long Beach Police Department said.

The device had been reported at 3:21 p.m. in the 2400 block of Long Beach Boulevard. An officer at the scene said the device was found in a trailer on 25th Street east of Long Beach Boulevard.

The city sent an alert saying officials expected the thoroughfare, just south of Long Beach Memorial, to be closed for at least three hours.

Officers evacuated residents in the surrounding area as the bomb squad responded.

Metro train service was also halted between Willow Street and Pacific Coast Highway due to the activity.
