There's an old blog post at

On June 11, 1946, Star House Movers began driving the 160-foot-long wing sections on a 28-mile route to Terminal Island. From the 15th to the 16th, the hull of the plane was moved. Utility companies had to raise or cut 2,300 power and phone lines along the route, which took the hull down Santa Fe Avenue and eventually over the Pontoon Bridge onto Terminal Island.
