The Formula 1 United States Grand Prix is picking up speed and with the crowds of people expected, law enforcement will be controlling traffic in Elroy and writing citations.
"Folks walking, riding a bike, stopping or standing in their cars around the track blocking traffic. There are no sidewalks in that area. There's no place for pedestrians to walk safely in that area," said Roger Wade, Spokesperson with Travis County Sheriff's Office.
On Friday afternoon, FOX 7 found signs like this one showing "no walking" But found plenty of people ignoring it.
The goal Wade says is to keep everyone safe. If you're caught walking or cycling near the tracks, you could face up to a $500 fine.
Wade says cyclists do have an option.
"There is a bike route that goes from Downtown to Richard Moya Park once you get to that park there will be an area available to lock up your bikes and the shuttle will take you the rest of the way to the track because there is no bike lanes out to the track," said Wade.
Traffic is also a concern away from the track. On Friday evening, road closures backed up traffic in downtown Austin. As buses loaded with passengers, traffic slowed near the shuttle site at 15th Street and Trinity. Agencies at the local, county and state level are working together to monitor traffic from all angles.
"We've got close to 120,000 spectators who are coming to Austin to watch the race. We've got a lot from the region coming to participate in the festivals and concerts and so it's really important that all hands be on deck, not just form the city, but the county and public transportation agency," said Rodney Gonzales, City of Austin Economic Growth and Redevelopment.
They hope everyone will have fun, be patient and safe.
Shuttle bus service will begin at 7 a.m. Saturday.
