ADOT inspectors spent time Friday morning getting a closer look at the steel-girder system supporting the ramp that connects westbound I-10 with northbound I-17. The inspection confirmed that the fire did not affect the girders or concrete sections of the ramp.
The right lane of the ramp had been closed overnight as a precaution, but was reopened to traffic Friday morning.
Nearly 60 firefighters worked on three building fires possibly started by a spark from welding.
