Just installed on I-275 are numerous radar towers, starting just after I-75. They go until at least Busch (have not been past it lately) and are really too close to accelerate/decellerate between them. Again these are brand new, if you haven’t seen them yet, look next time you’re out. I drive this stretch every week and just noticed them this week (5/25/05). They don’t appear to be working yet, but should be soon since car patrols have dropped off.
