This was rather an opportune prompt as we have been having a bit of work done in one of our fields. The bankings of this burn (stream) are getting washed away and previous attempts to make a bridge did not last through winter storms and the high volume of rain we have had in the last couple of years. So we decided it was time to get serious! The contractor came yesterday and placed these concrete pipes in the water and surrounded them by huge boulders and sub-base. It's not quite finished yet, but hopefully this will mean better access to the rest of the field for the tractors which means that the field can be used for crops as well as grazing cattle.
