A Culvert is a pipe (less than 3m in diameter) or half-round flume used to transport or drain water under or away from the road and/or right of way. Culverts that are greater than or equal to 3m in diameter are stored in the MoT Bridge Structure Road Dataset. It is a Point feature

A Retaining Wall is a structure designed to protect the road infrastructure by retaining materials on the fill side to prevent road bed slips and by retaining materials on the cut side to prevent the road surface from being covered by debris. Retaining walls that are greater than or equal to 2m in height are stored in the MoT Bridge Structure Road dataset. It is a Linear feature

A Drainage Appliance is an apparatus (that has not been described as a culvert), or earth works, designed to facilitate the movement of water in a controlled manner. Drainage Appliance include some appliances/earth works that work in conjunction with culverts. It is a Point feature

A Special Lane defines the number of special lanes that are not defined as through travel lanes, passing lanes, or truck lanes which are described in the Highway Profile dataset. It is a Linear feature
