Bridge Style - Specify start gap length

Entities that are bridged with this bridge style will have what is effectively a Spanish Bridge at the start (this is the Gap), followed by the appropriate number of bridges with a fixed distance between them.

Fixed Number

Switch this option on if a fixed number of bridges should be added to all entities regardless of their length. Enter the required number.

Maximum length with no bridges

Enter the maximum length an entity can be without having bridges added to it.

Start gap length

Enter the required gap length as described above.

Minimum End Land Length

Enter the minimum land length allowed at the end of the entity.

Tie Bridges

These are generally smaller bridges that may be added to shorter entities. Select this option if they are to be used.


Enter the required width of a tie bridge.

Maximum Length

Enter the maximum length that an entity can be before it has to have a standard bridge rather than a tie bridge.

Standard Bridge
