Solid objects built to safely cross rivers or from ground to house, house to house.

Survey
Survey will give you information on where the other character is standing regarding distance, direction and height difference.
To survey for a bridge two characters are needed. One character must carry a range pole, the other a dioptra. The lowest quality of the two items determines how long a bridge is that you can survey.'
The character with the range pole does not have to do much besides holding the range pole. To do this activate the range pole, click the ground and select Hold from the menu. When the action timer starts face the character with the dioptra.
The character with the dioptra will do the actual survey. Activate the dioptra, right click the player holding the range pole and select Survey from the menu.
The planning process will print messages in the event log
You carefully place the dioptra on its tripod in front of you. You make sure the dioptra is level. You point the dioptra at <other player>. You wave at <other player>. You line up the dioptra with <other player>. You look through the dioptra. You focus on the range pole. You read the graduations on the range pole and work out the height difference. <other player> is <x> tiles <direction> of you. Also you appear to be <x> dirt higher than <other player>. You stop surveying. You pack up the dioptra.
Building
To plan a bridge two characters are needed. One character must carry a range pole, the other a dioptra.
The character with the range pole does not have to do much besides holding the range pole. To do this activate the range pole, click the ground and select Hold from the menu. When the action timer starts face the character with the dioptra.
The character with the dioptra will do the actuall bridge planning. Activate the dioptra, right click the player holding the range pole and select Plan bridge from the menu. Standing right in front of the other character will create a 1 tile wide bridge. Standing at an offset will create bridges multiple tiles wide.
The planning process will print messages in the event log
You carefully place the dioptra on its tripod in front of you. looks like bridge would be <'width'x'length'> (East-West) The tile border to your <direction> is level You make sure the dioptra is level. You point the dioptra at <other player>. You wave at <other player>. You line up the dioptra with <other player>. You look through the dioptra. You focus on the range pole. You read the graduations on the range pole and work out the height difference. The tile border to your helpers <direction> is level You check the heights of the plan ends. <Height difference>. You work out the orientation and width for the bridge. You check for clearance between the bridge ends. You check for protruding foliage. You check for nearby cave entrances and any lava. You check for any items in the way. You check that you have permissions to build the bridge. You check for any bridges that may interfere with this bridge. You check there would be no buildings under this bridge. You work out the styles of bridges that would fit. You start working out the bridge components required. Planned bridge area is <x> tiles long and <y> tile wide. (23:ESabFFFFFFFFFFFFFFFBASE) You stop surveying. You pack up the dioptra.
When all requirements are met you are presented with list of possible bridges.
The selection depends on planned width, length, height difference and clearance below the planned bridge.
If you have choosen a flat bridge that is longer than 5 tiles then you have the possibility to change the schematic of your bridge plan.
When you have choosen a type of bridge you can name the planned bridge and select the steepness of the bridge if you've choosen an arched bridge.
After clicking Finalize a wooden frame for the bridge is constructed.
For each tile of the bridge a bridge segment has to be completed in multiple stages. Those are 'abutments' for the out segments, 'bracing' and 'floating' for stone bridges and 'crown' for rope and wood bridges.
Until the bridge has been completed no other bridge can be started by the character.
Bridge Warnings and Possible Solutions
Your end of the bridge is too close to the water level!
- Both ends of the bridge need to be 10 dirts higher than water level.
"The quality of the dioptra makes it too hard to work out the distance." or "You can't read the graduations on the range pole at this distance".
- Improve both items. Note that the lowest QL of the two will determine the max length of bridge you can plan.
You notice that there is not enough clearance for a bridge to be built here.
- Remove trees, houses, fences at both end tiles where the bridge should have enough drop off.
There are some terrains nearby
- A cave entrance is one factor. Make sure to build the bridge at least 2 tiles away from the opening.

Notes
- Some Bridge info may be found in the week 43 news post here: http://forum.wurmonline.com/index.php?/topic/112518-news-update-work-and-progress-week-43/
- Bridge material calculator located here: http://forum.wurmonline.com/index.php?/topic/122044-bridge-material-calc/
- Each house floor is calculated as 30 dirt slope, you need to be higer from water level for arched bridge atlast 10 slope.
