Conroe, TX – A major stretch of Interstate 45 northbound in Montgomery County is shut down today as law enforcement works an active investigation involving a suspect vehicle near FM 830 at League Line Road.
According to the Montgomery County Sheriff’s Office, deputies are assisting Conroe Police with the stop and investigation, which prompted the full closure of all main northbound lanes of I-45 in the area. Officials indicated the shutdown remains in effect as authorities secure the scene and continue investigative efforts.
Heavy traffic congestion quickly built across the northbound corridor, with vehicles backed up for miles during peak travel hours. Drivers are being urged to avoid the area and seek alternate routes, including local frontage roads and nearby highways, as delays are expected to persist throughout the response.
