Methods, systems, and apparatus, including computer programs encoded on a computer storage medium that create lane graph geometries from lane graph topologies. One of the methods includes receiving data representing a topological lane path through a plurality of cells of a drivable region. From the topological lane path, an initial polyline that traverses the same plurality of cells as the topological lane path can be generated. The initial polyline can be defined by vertices located on edges of a triangulated decomposition of the drivable region. A geometry optimization process can be performed on the initial polyline to generate a final polyline according to optimization criteria. From the final polyline, a geometric lane path representing a geometry of a drivable lane that traverses the drivable region can be generated.
