MONTREAL - Thursday is the annual "In town without my car" day, part of the 9th annual car-free week, although you may be forgiven if you don't notice.

Several streets are closed to traffic for banker's hours on Thursday to promote car-free commuting and environmental awareness, but unlike previous years where a large section of St. Catherine St. was closed in order to prevent cars from getting through, and forcing drivers to detour around the entire area if they wanted to go north or south, this year cross-streets will remain open.

Ste. Catherine St. is closed between McGill College and Bleury between 9 a.m. and 3:30 p.m., but drivers heading north or south in those areas will be able to get through without any delays.

The stretch of Ste. Catherine St. between Bleury and St. Urbain, along with Jeanne Mance between Rene Levesque and de Maisonneuve, has been closed since Saturday and is scheduled to re-open at 5 p.m. on Sunday Sept. 25.

And starting at 6 p.m. tonight, a large square around the Quartier des Spectacles will be closed because of a free outdoor concert by Arcade Fire.

Several activities are scheduled to take place on the streets today, including a mini-putt golf course at the corner of University and Ste. Catherine Sts., group workouts in Phillips Square, seedling distribution for people who want to plant trees, and a performance by the McGill Choir.
