In the three years that Emmert International worked on its transport plan for the four ConocoPhillips megaloads, project manager Mark Albrecht said, "I'd have to say that route's been measured at least 25 to 30 times. ... We really wanted to make sure that we ... met the requirements and get through there safely." He said his company also hired outside firms to do some measuring and study of the route, and developed a video of the entire route. "There were some tight areas, and in those tight areas, engineering came back and said if we would modify the saddles" within the trailer configuration, the loads would have more room to maneuver, he said. Those changes then were made, Albrecht said, "to enhance the safety and maneuverability of the trailer."
