 Oregon's Department of Transportation says Interstate 84 in Portland is cleaner following a massive weekend effort. The stretch of freeway known as the Banfield between I-205 and I-5 closed for 13 hours Saturday night so crews could paint over graffiti, pick up trash, and replace around 40 damaged signs. Next time you come through the corridor, you'll see many new signs, you'll see things that are quite a bit different, and you'll see that cleanup effort really coming to fruition.
