Anywhere on the west part of Loop 820 around Fort Worth. From the Lake Worth bridge to to Highway 377 South. This part of the loop is the least congested, but has speed limits lower than other parts of the loop, and even lower than some inner city freeways. Most of it is six lanes. But, there is almost always at least one traffic unit out with radar. It is patently obvious that the conditions here are no more than a money making speed trap.
