Main Boulevard represented the principal thoroughfare in the city of Theed on the planet Naboo. This road stretched from Palace Plaza all the way to Theed's elaborate ceremonial gates. Its termination point was Main Boulevard Bridge, which spanned a branch of the Solleu River.
During the Invasion of Naboo in 32 BBY, the Main Boulevard, along with its associated bridge, functioned as the main route for a procession of the invading Droid Army belonging to the Trade Federation.
