== Bridge Warnings and Possible Solutions ==
'''Your end of the bridge is too close to the water level!'''
*raise both tiles Both ends of the one holding the range pole and dioptra by bridge need to be 10 slope dirts higher for 5 tile-long bridge and 60 - 80 slope beyond itthan 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 materialsitems. Note that the lowest ql QL of the two will determine the max length of bridge you can plan. Maximum length is QL x 0.4 rounded up.
'''You notice that there is not enough clearance for a bridge to be built here.'''
*Remove trees, houses, fences and at both end tile tiles where the bridge should have enough drop off.
