Those streets will differ in when they're closed based on which part of the course they are located in and how long marathoners will be expected to finish that section of the course. The beginning of the course streets will be closed from 5:30 a.m. to 9 a.m. and the last piece of the marathon will be closed from 8:45 am to 4 pm.
