The shuttle made stop-and-go progress, with some halts to check its balance on its 160-wheeled carrier and to prune trees in its path as it rolled past strip malls, storefronts, apartment buildings and front lawns.
'It's still a work in progress,' Scheier said.
The shuttle was to travel three miles and then stop in a private lot for a nine-hour layover as crews deal with power lines father ahead on the route.
Ushering a shuttle through an urban core is a logistical challenge that took almost a year to plan.
