On 150 – Martin Luther King heading into Danville. When the speed changes from 55 to 50 mph. Slow Down. Just after the road goes from divided to single you will see a road bridge and then a railroad bridge – between the two bridges there is an area of grass, and that is where the Cops hide with their speed guns. Sometimes they are on the far side of the railroad bridge. I’ve got a ticket there, so be careful. You cannot see the cops until your are right there, and then its to late to take action. I always slow down at the 50 sign.
