A wrong-way driver crossed the Champlain Bridge around 3:30 this morning.
Police say the driver boarded the wrong side of Autoroute 10 at Highway 30 and headed toward Montreal. As he approached the bridge, a horrified driver who spotted him whipped out a cellphone and alerted police.
The wrong-way driver made it across the span, perhaps startling oncoming motorists but without causing any accidents.
A patrol car caught up on the Montreal side of the bridge.
A 49-year old man is under arrest, facing charges of impaired driving and dangerous driving.
