Workers this week have been dismantling a 32-foot-long covered bridge that spans Tumalo Creek near the center of Shevlin Park. The bridge was seen in the 1993 Walt Disney Studios movie “Homeward Bound: The Incredible Journey.” Its distinctive appearance prompted calls to save it. But after a routine inspection three years ago, the Bend Park & Recreation District determined that the century-old abutments that support the bridge were near the end of their useful life. The bridge abutments were originally built for the Brooks-Scanlon railroad trestle. Disney built walls and a roof on the existing bridge so it could be used as a set during a short scene in “Homeward Bound.” The park district said repairing the bridge would have been prohibitively expensive.
