Well, we don't have one of these, so here it is:
I found this on NICE's website
n45,n46,n50-EXPECT ROUTE DELAYS Fridays thru August 31st, 6 p.m. until 9 p.m.
n45, n46, and n50 buses will be detoured off of Broadway east of the Bellmore LIRR station Friday nights during the summer, due to a weekly car show. Southbound buses will turn off right off of Bellmore Avenue on to the Sunrise Highway, where they will travel west to Bedford Avenue. They will then turn left down Bedford Avenue resuming their regular route.
Please allow additional travel time on this morning, to ensure you arrive at your destination on time
