A tense standoff between police and a man threatening to blow himself up ended early Tuesday morning.

Highway 400 reopened in both directions at Aurora Rd. overnight after the man surrendered to authorities following several hours of negotiating. It all began at about 9:30pm Monday, when the man allegedly told police he'd detonate several propane tanks in his car when the next tanker truck drove by.

The suspect, 44-year-old Roderick Anderson of Nottawasaga Township, turned himself over to police just after 1am. He faces several charges.

The closure meant thousands of drivers were stuck on the road for hours, wondering what was going on.

"Been here for two hours," noted Allen Mizrachi. "Some people are running out of gas and it's getting cold out."

Another motorist, Joe Tiano, added, "Look at this. It's for miles. We'll get home eventually."

And driver Geoff Perry complained, "I think it's rather ridiculous. We've got to work in the morning and so does everyone else here. What's going on up there?"

The highway was reopened in both directions by 3am, meaning a wait of several hours for some people and undoubtedly a tiring day at work on Tuesday.
