The space shuttle Endeavour reached its resting place in Los Angeles a day later than expected.
The 80-tonne shuttle travelled through the streets of LA at a speed of 3km/h.
Hundreds of trees, traffic lights, power lines and parking meters were removed to clear a path for the shuttle.
But technical hitches mean it did not reach its final destination, a museum, on Saturday, as planned.
The BBC reports some trees were too valuable to be cut down and the shuttle's wing had to be manoeuvred around them.
Endeavour arrived at Los Angeles international airport three weeks ago. It left there on Friday morning to travel to the California Science Center on the other side of the city.
The spacecraft entered service in 1992, making 25 trips and circling the globe almost 4700 times.
