For the second year, sites around Calgary are baring all in the name of promoting public interest in heritage and architecture.

The Doors Open concept has been making its way around the globe since the first event in France in 1984 with initial Canadian appearances in Toronto and Montreal. Last year's event in Calgary saw 16,500 visits with the support of more than 200 volunteers.

After significant flood damage, 57 kilometres of Calgary pathways — of the 93 affected — have been reopened in just over two months.

While progress has been made, the 36 remaining kilometres of about 25 sections of pathway will take time to repair due to environmental and landownership considerations.

The City has finalized negotiations with Siemens Canada for the purchase of 60 new LRT cars.

Since December 2012, Calgary Transit had been in the process of selecting a new, long-term strategic partner for the supply of new vehicles. Siemens — out of Sacramento, California — and their S200 vehicles was one of five companies bidding for the project.

Offering Calgarians a behind the scenes glimpse of local sites, Doors Open YYC 2013 has announced this year's locations.

Taking place in conjunction with Alberta Culture Days, the free, threeday public event gives locals a chance to have behind the scenes access to parts of Calgary often never seen. After last year's inaugural event, Calgarians will have access to 12 sites in addition to other facilities located throughout the city.
