HANNIBAL, Mo. -- A bomb threat shut down the Mark Twain Memorial Bridge on Interstate 72 on Thursday night.
Our news-gathering partners at WGEM reported that the Mark Twain Memorial Bridge on Interstate 72 that leads into Hannibal was shut down after someone called in a bomb threat to dispatchers at the Marion County 911 Center.
WGEM reported that Marion County Sheriff Jimmy Shinn said the call came in at 8:45 p.m., and the caller said there was a bomb on the bridge that would detonate in an hour.
Sgt. Eric Brown with the Missouri State Highway Patrol said a patrol boat was on the Mississippi River with investigators searching underneath the bridge for any possible explosive devices. Bomb technicians and K-9 crews with the Illinois State Police also were called in to investigate.
WGEM reported that the bridge opened just before midnight. While the bridge was closed drivers were encouraged to cross the river at Quincy or Louisiana, Mo.
