If you build a streetcar, they will come. That has been demonstrated across the country with the 21st century streetcar.

The streetcar in Denver brought 7.8 million square feet of commercial development from 2004 to 2009. The Charlotte streetcar added 9.8 million square feet.

But what will come in Tucson? Downtown, 4th Avenue, Main Gate Square and the University of Arizona don’t want to wait to find out or leave it to random forces.

You might have a few questions about Revolutio, the new, eclectic boutique at 43 S. 6th Ave. that leans toward women’s fashions but, by no means, stops there.

The first question could be about the name, Revolutio. No, there is not a missing n. Owner Heather Lindquist went for a Latin spelling.

“It means a turn around, two bodies orbiting each other,” said Lindquist, a professional photographer who knows her way around retail fashion.

Six years of Modern Streetcar talk will finally translate into streetcar action with the very long-awaited track installation set to start by the end of April.

Congress Street, Broadway, a section of 4th Avenue, University Boulevard and 2nd Street through the University of Arizona will all have driving restrictions, especially through the summer months, and continuing to the end of 2012.

“We want to get as much done in the summer months as we can,” said Jesse Gutierrez, streetcar construction manager for the Tucson Department of Transportation.
