Four years ago, LDS-owned Property Reserve, Inc. and Taubman Centers began construction on downtown's biggest revitalization project in a half century, City Creek Center.

The center is slated to open March 22, 2012.

Covering 20 acres between South Temple and 100 South and State Street and West Temple, the erstwhile footprint of  ZCMI Center and Crossroads Mall will offer housing, commercial  and retail space, not to mention multi-level sidewalks, six acres of green space, fountains and a stream.

A pedestrian skyway will link the two city blocks across Main Street.

Ron Loch, VP of planning and design for Taubman Centers, said creating an urban center in SLC was done with sustainability and access in mind.

Office, retail and residential buildings are built using recycled material, the  ZCMI facade is repurposed as anchor tenant Macy's storefront.

The retail portion of the center will feature a retractable roof which captures solar heat during the winter and will provide natural cooling during the summer, Loch said.

Cyclists and pedestrians will have easy access to TRAX.

Developers say City Creek Center is expected draw 10 million annually. For more information information click here.
