In one embodiment, a method is provided for componentized junction models. A plurality of road junction configurations are defined with a different set of road segment models corresponding to each of the plurality of road junction configurations. One of the plurality of road junction configurations are selected for a route through a physical road junction. A model of the physical road junction is generated by assembling the set of road segment models corresponding to the selected road junction configuration. The three-dimensional model of the physical road junction is rendered.
