A method, apparatus and computer program product for detecting a start location and an end location of a bridge are described herein. In the context of a method, one or more sequences of images, at least one sequence of images corresponding with a side barrier portion of the bridge, may be identified from image data corresponding with a probable location of the bridge. Each side barrier portion may comprise a plurality of side barrier segments. The method may identify one or more characteristics of the plurality of side barrier segments. The method may determine the start location and the end location of the bridge based at least in part by identifying characteristic differences of the plurality of side barrier segments. The method may cause transmission of information corresponding with the start location and the end location of the bridge for updating a mapping or navigation system.
