WINDSOR, ONT. -
The Detroit-Windsor Tunnel has reopened Thursday afternoon after police inspected and cleared it for a bomb threat.
Windsor police received an anonymous call earlier in the day saying there were explosives in the tunnel and immediately evacuated all employees and travellers.
Shortly before 4:30 p.m., Windsor police tweeted that the tunnel "has been fully inspected with police" and was set to reopen at 5 p.m.
Detroit and Windsor police blocked off both sides of the border, causing a major traffic jam in both cities.
The Detroit-Windsor Tunnel is an underwater tunnel that connects Windsor, Ont., with Detroit, Mich. The tunnel is about 1.5 km long.
