Bridges

The tags defined on this page will render in various nautical charts (zoom-level 16 and higher).

An other example: Navigable Waterways, Europe (zoom-levels 1-13)


For routing purpose, the tag should be placed on the waterway beneath the bridge.

This page defines tags for the attributes of bridges.

Type S100 code seamark:type=* Definition
Bridge BRIDGE bridge A structure erected over a body of water to provide a roadway for vehicles, pedestrians or to carry utility services.

Categories

Category (CATBRG) seamark:bridge:category=* Note Definition Photo
Fixed bridge fixed preferred category. If known, add seamark:bridge:clearance_height=* A bridge having permanent horizontal and vertical alignment.
Opening bridge opening preferred category. If known, add seamark:bridge:clearance_height_closed=* A bridge that is closed when set for carrying road traffic and open when set to permit marine traffic to pass through the waterway it crosses.
Lifting bridge lifting preferred category. If known, add seamark:bridge:clearance_height_closed=* and seamark:bridge:clearance_height_open=* A movable bridge (or span thereof) which is capable of being lifted vertically to allow vessels to pass beneath. MovableBridge lift.gif
Swing bridge swing opening, if known, add seamark:bridge:clearance_height_closed=* A movable bridge (or span thereof) which rotates in a horizontal plane about a vertical pivot to allow the passage of vessels. MovableBridge swing.gif
Bascule bridge bascule opening, if known, add seamark:bridge:clearance_height_closed=* A counterpoise bridge rotated in a vertical plane about an axis at one or both ends. MovableBridge draw.gif
Pontoon bridge pontoon ambiguous: might be fixed or opening A fixed floating bridge supported by pontoons.
Drawbridge drawbridge opening, if known, add seamark:bridge:clearance_height_closed=* A general name for bridges of which part or the entire span of the bridge may be raised or drawn aside to allow ships to pass through. Drawbridge.gif
Transporter bridge transporter fixed, if known, add seamark:bridge:clearance_height=* A bridge that has towers on each side of the waterway connected by a girder system on which a carriage runs. MovableBridge transport.gif
Foot bridge footbridge ambiguous: might be fixed, opening, lifting A bridge structure used only for pedestrian traffic.
Viaduct viaduct fixed, if known, add seamark:bridge:clearance_height=* A long bridge consisting of a series of beams, spans or girders (of steel, timber or concrete) supported on towers or piers and used to carry a road, railroad, etc.
Aqueduct aqueduct fixed, if known, add seamark:bridge:clearance_height=* A bridge supporting an artificially elevated channel, for the conveyance of water.

Attribute seamark:bridge:<attribute> Value type Definition
Horizontal clearance (HORCLR) seamark:bridge:clearance_width=* Decimal The width that is available for safe navigation.
Vertical clearance (VERCLR) seamark:bridge:clearance_height=* Decimal The vertical clearance measured from the surface plane towards the object overhead.
Vertical clearance, closed (VERCCL) seamark:bridge:clearance_height_closed=* Decimal The vertical clearance the bridge in closed condition measured from the surface plane towards the object overhead.
Vertical clearance, open (VERCOP) seamark:bridge:clearance_height_open=* Decimal The vertical clearance of the bridge in opened condition measured from the surface plane towards the object overhead.
