Cyclists to your bikes – the "Cannon Expressway" is to open Friday.

Mayor Bob Bratina will help inaugurate the two-way bike lanes on Cannon Street at noon.

The ceremony, at Cannon and James Street North, is being timed with Supercrawl. The mayor will be joined by Justin Jones from Yes We Cannon, councillors and city staff.

The three-kilometre tack runs on the southside of Cannon from Sherman Avenue North to Hess Street North. It includes planter boxes, bollards and rubber curbing to separate cyclists from traffic. The city says a short event will be staged to mark completion of the track.

The $867,000 project was approved by council in March, despite concerns about cost and consultation. The original estimate was $600,000. Annual maintenance has been set at $240,000.
