A truck crashed into a house in Old Town on Wednesday evening, landing on its side, causing structural damage to the building and forcing the closure of a busy street. The truck was traveling downhill on Marsac Avenue close to the Marsac Building when the brakes failed at approximately 5:30 p.m., a Park City Police Department officer who responded said. Officer Mikel Archibeque said the driver was not injured and nobody else was inside the truck. There were no known injuries inside the house, 316 Marsac Ave., just after the accident.
