The City of Calgary has enacted its Snow Route parking ban following the snowfall of Wednesday evening and Thursday morning.

All vehicles must now be removed from designated Snow Routes until the ban is lifted.  Any offending vehicles are subject to parking fines and may be towed.

In the first twelve hours of the parking ban, between 6:00 a.m. and 6:00 p.m. Friday, 648 tickets were issued.

The parking ban will remain in effect for up to 72 hours.

Snow routes are designated by a blue sign with a white snowflake symbol.  Snow routes consist of major roads, collector roads and bus routes.

This is the city's first snow ban of 2013.

Calgary experienced just one other snow parking ban this winter, back on November 11.

Then, the Calgary Parking Authority issued 355 tickets.

Fines for violating the ban are between $40 to $75 depending on when you pay them.
