A man suffered a severe head injury when he was struck by a vehicle while cycling near the intersection of Elgin Street and Laurier Avenue W. on Thursday morning.
It happened at about 7:20 a.m. on the westbound lanes of Laurier Avenue W., not far from where traffic from the Queen Elizabeth Driveway merges onto Laurier.
The cyclist, believed to be between 55 and 60 years old, suffered multi-system trauma and head injuries after he was thrown off his bicycle, according to paramedics.
The driver of a black van stopped on the Mackenzie King Bridge nearby, left their vehicle and fled the scene, according to Ottawa police.
An arrest has not yet been made.
Police have closed westbound Laurier Avenue W. between Elgin and Nicholas streets, northbound Elgin Street from Laurier to Slater streets, and the eastbound lanes of the Mackenzie King Bridge, pushing buses that normally stop there to Rideau Street.
