LAS VEGAS (KTNV) - A viewer was concerned about an apparent crack in the flyover bridge on Interstate 15 and Spring Mountain Road.
The Nevada Department of Transportation says it's not a crack. Rather, it's an expansion joint that lets the concrete expand and shrink for changes in temperature. It also protects the bridge during earthquakes.
