COVID-19 Update: To see how we’re preparing for your visit, and to ensure your health and safety while you’re here, please view our Operational Plan


Cancelled for 2020 Due to COVID-19

At ERX, our first priority is always ensuring the health and safety to all who enter our facility. This year, more than ever, we are facing challenges in the event industry which have made it difficult for us to host nearly any event. After many conversations with state-level employees regarding restrictions on traditional seating and group sizes, we have made the difficult decision to cancel Monster Truck Mayhem, which was set to take place at ERX Motor Park on August 28 & 29.

Back by popular demand! The fun, roar and larger than life excitement of Monster Truck Mayhem returns to ERX Motor Park! Experience Monster Trucks like never before; the big tires and big thrills of this event have quickly become a favorite, especially among families.

Get here early for your chance to view the trucks up close, take a ride-along, and partake in our kid zone activities. Be sure to stick around after the show for a chance to chat with the drivers for an autograph signing. Watch these monsters catch massive air, crush cars and spin high-roost donuts with seating so close you’ll feel the earth rumble.
