Detroit-Windsor Tunnel resumes normal operations after Rainbow Bridge explosion

The Detroit-Windsor Tunnel has resumed normal operations after being under a "heightened level of security" in wake of a fatal vehicle crash and explosion at the Rainbow Bridge on Wednesday.

As of about 7:20 p.m., the tunnel's CEO said traffic is moving well and delays are less than 10 minutes in each direction.

Earlier on Wednesday, officials said they were monitoring the situation at the Ambassador Bridge as well.

As of 3:30 p.m., there were no apparent extra security measures at the Ambassador Bridge crossing. But a border agent told a CBC News reporter they are on high alert and "today is not an easy day."

The crash and explosion took place on the American side of the Rainbow Bridge in Niagara Falls.

New York Gov. Kathy Hochul said there's no indication that the incident — which killed two people  — is linked to terrorism.

"Based on what we know at this moment, there is no sign of terrorist activity in this crash," Hochul said at a news conference.

While all of the Niagara-area crossings were closed for part of the day on Wednesday, only the Rainbow Bridge remains shut down as of 7 p.m.

Minimal delays at the border in Windsor Wednesday evening

The Canada Border Services Agency (CBSA) is reporting a 25-minute delay for commercial traffic crossing at the Ambassador Bridge and no delay for travellers coming into Canada as of about 7:30 p.m.

The U.S. Customs and Border Protection is reporting no delays for commercial traffic and a 20-minute delay for passenger traffic at the Ambassador Bridge crossing into the United States as of 7 p.m.

Meanwhile, officials said Wednesday afternoon that security had been stepped up proactively at the Gordie Howe International Bridge construction site and the University of Windsor, which is adjacent to the Ambassador Bridge.

Windsor Mayor Drew Dilkens said on X, the platform formerly known as Twitter, that he was monitoring the situation for any potential impacts to the city.

NDP MP Brian Masse (Windsor West) said in a post to X his thoughts were with responders and border officers. 

"All of us who live and work in border communities know how integrated and connected we are in both countries," he wrote. 

Liberal MP Irek Kusmierczyk (Windsor—Tecumseh) said on social media the government was taking the situation in Niagara Falls "extremely seriously."

"The Prime Minister, Public Safety Minister, RCMP & CBSA are all fully engaged & providing necessary support," he wrote on X. "We will continue to work closely with U.S. officials and share further updates with Canadians."
