My friend Dayna Budde visited Universal and kindly sent along pictures from the various sets used time and again in Voyagers! Below are the shots she took in 2008. After looking at all these images, one comes to learn that Voyagers and Universal Studios in general got a lot of mileage out of their sets! And no doubt still do today. I have seen these sets used in two of my other favorite Universal shows, The Incredible Hulk and Quantum Leap.
2 shots of the New York streets, seen in Various Episodes of the series. Most notably, Cleo and the Babe & The travels of Marco Polo... and Friends.
Edison's house and Laboratory from World's Apart.
A section of the Mexican town, seen in many different episodes, particularly, Bully and Billy, World's Apart, and The trial of Phineas Bogg.
