Baton Rouge alternate route for downtown

I am coming in town tonight from Houma for a rehearsal and was wondering the best way to get to Downtown BR with the Memorial taking place today. I wont be leaving Houma till about 5pm so maybe the traffic will be better by then but was looking for a plan B. I will be stopping at Embassy Suites first to check in before heading downtown so any help is appreciated. If I get caught up in traffic, so be it, it is for our fallen brothers in Blue and I can deal with traffic any day for these guys putting themselves in harms way to protect us. TIA
