Changes are underway to make sure you stay safe as thousands of people come to Las Vegas for the Conor McGregor and Floyd Mayweather Jr. fight.
The President of the Fremont Street Experience, Patrick Hughes, says he and other local authorities got together after the deadly attack in Barcelona to discuss what could be done better in Las Vegas to keep us all safer.
"We are here to do the best we can to protect the environment. It's our job to take proactive steps to protect these areas and we believe we are headed in the right direction," said Hughes.
The big fight is just days away and huge crowds are expected to flood the streets all weekend long.
On Fremont Street, there are big barriers to deter vehicles from plowing through.
"That's what they are designed to do," said Hughes.
The barriers are temporary right now but authorities are working together to create permanent ones.
The permanent concrete barriers will be decorated by the art community to add a nice touch to the Fremont Street Experience.
People will also notice a greater police presence down on Fremont Street.
