If you're thinking about driving down South First Street, you might want to rethink your route. A flatbed semitruck driving south on First tried to make a turn to head west on Walnut. The truck clipped a pole holding up all of the signal lights, knocking the lights to the street and shutting down the intersection. Fortunately no one was hurt, but Yakima Police expect the intersection to be closed at least until 9 o'clock tonight.
