The present disclosure provides a method and apparatus for generating route information, a device, a medium and a product, relates to the field of computer technology and specifically to the field of artificial intelligence technology, and can be applied to map navigation scenarios. A specific implementation comprises: acquiring an origin and a destination; determining a candidate route set based on the origin and the destination; generating, for each candidate route in the candidate route set, weight information of the candidate route based on a predicted closure time length of a closed road, in response to determining that the closed road is present in the candidate route; and generating route information based on the weight information of the each candidate route in the candidate route set.
