Birmingham PD is using BPD Ch 8 - Events 3 for traffic control related to the Mercedes Marathon held here this AM. Also using it to help co-ordinate directions for runners. Had some problems with the set up of some barricades this morning between 5:00 A.M. and 6:00 A.M. Ended up the PD had to move the barricades themselves. Also had some apparent confusion among officers working as to where they were supposed to be assigned. Pretty busy between about 5:00 A. M. and 7 A. M. when the race started.
