Best Practices for Barrier Protection of Bridge Ends

A general problem occurs at many bridge locations along highways where the required length of need for bridge approach rails cannot be met within the existing right-of-way limits. These conflicts occur when existing driveways, roads, or other objects are within the ROW. It is not unusual to have less than 15 feet length between the end of the bridg...
