Krissi and Shane McCollow were 8km away from the church where they would be married, when they smelt something funny inside the bus carrying their bridal party.
When smoke began billowing through the vehicle the couple became alarmed, according to USA Today.
"I was worried that it might stop and we may not get to the church," Krissi, 26, said.
"I just knew something wasn't right because of the smell and smoke."
After a warm journey, the bus made it to the church and everyone was safely unloaded when it exploded.
