Height restrictions

The height restrictions category of the wizard system is under the Restrictions and Decisions dataset of the Decisions Register. The altitude limits category in the Road Register was called TL 263 altitude limit. All obstacles to underpassing on public roads (except electrical wiring) are included in the height limitation material. The permissible underpass height shall be defined by driving directions. This allows for 2 different values on roads on 1 carriageways, in which case a half of the direction of the road’s measurement shall be given in focus. For sections of 2 carriageways, only one value per runway shall always be reported, i.e. the side shall not be specified (9). If necessary, the trajectory characteristics shall also be indicated by direction. The property descriptions of the wizard’s data can be found here: in the United States. The data cover the road network maintained by the Finnish Transport Agency.
