The Minnesota Department of Transportation as well as other highway departments have been considering the accommodation of pedestrians and bicyclists along their roadways and bridges. One area of particular concern are bridges with standard height rails. A standard height bridge rail, typically measuring 813mm in height, is not capable of restraining a bicyclist during even a minor impact with the bridge railing. To protect bicyclists, it is necessary to substantially increase the height of most TL-4 bridge rails. Since many existing railings have been proven adequate for containing vehicular impacts, this rail height extension could be utilized on a number of different TL-4 barriers once testing has showed the extension to be crashworthy.
