CARMEL, Ind. -- Carmel, the country's roundabout leader, wasn't always as spread out as it is now.
In 1984, the Hamilton County city was constrained to approximately west of Keystone Parkway, east of Guilford Road, north of 116th Street and south of Main Street.
About 20 years later, the city had expanded west to U.S. 31, with many smaller streets being built for houses, especially west and north of the city.
