Formula One is going to bring a lot of traffic to Southeastern Travis County and that's prompted the Del Valle school district to call a holiday on Friday. The district's Celina Blye says it's a safety issue, since they don't know what to expect with traffic and the crowds. 

She says there are concerns that traffic will be so heavy that teachers and other stuff might not be able to get to work. Also students could have trouble getting to class or be put i dangerous situations with so many cars around. 

Blye says they've contacted the Texas Education Agency for a waiver, so that the students don't have to make up that school day.
