All lanes of Interstate 95 northbound in Laurel were shut down at about 2:45 p.m., and just one lane was open as of 4 p.m., according to Maryland authorities.

Corporal Robert L. Payne, of the Maryland State Police, said the highway was closed in response to a “suicidal subject” who apparently jumped from Laurel’s Brooklyn Bridge Road overpass onto I-95’s northbound lanes. All lanes of traffic were immediately shut down.

Mark Brady, spokesman for the Prince George’s County fire and emergency services department, said all fire and rescue vehicles had left the scene as of 3:45 p.m.

Payne said traffic in the area would likely continue to be slow until at least 6 p.m. as police continue to investigate.
