The Sprague Avenue of the 1950s, '60s, '70s, '80s and even the '90s isn't coming back. That's the message an urban design consultant gave Spokane Valley citizens and elected officials Tuesday.

Instead they're going to malls and to the intersections of major streets, where retail shops are being clustered in attractive ways, said Michael Freedman, of San Francisco-based Freedman, Tung & Bottomley.
