PITTSBURGH — "Worlds Away: New Suburban Landscapes" opens Oct. 4 in the Heinz Architectural Center at the Carnegie Museum of Art, 4400 Forbes Ave.

More than half the population lives in suburbs, and between 1992 and 2002 alone, nearly 23 million acres of agricultural land in the United States succumbed to development.

A historical review of the evolution of suburbs since the late 19th century will set the stage for the exhibition's principal component: commissioned architectural proposals for remediating the consequences of unchecked outward development.

The exhibit will continue through Jan. 18.

Museum hours are 10 a.m. to 5 p.m. Tuesdays through Sundays. Closed major holidays.

Admission, which includes the Carnegie Museum of Natural History, is $15 for adults, $12 for senior citizens, and $11 for students and children age 3 and older.
