Upon exiting Freeway 77 onto the Loop 290 heading into Smithville, the speed limit is clearly marked at 50 mph. Less than 50 yards from the 50 mph speed sign, there is a less obvious speed sign posted 35 mph. The police car is hidden by this sign. Unsuspecting visitors, even if the 35 mph sign is seen, cannot slow down fast enough to avoid the radar. The fine is $115 plus $5 for every mile over the speed limit. I was caught at 48 mph – obviously slowing down after seeing the 35 mph sign.
