The deed named "Fake Lake Market" of the player Locath seems to be directly affected by this. Don't know if he is part of your group or not and if he agrees with this.
If you have already contacted him or if he is part of your group and does agree with these changes then this is fine and you can continue. If you didn't contact him yet then please do so now before making any changes. Also please make sure that the new road is finished before you remove the old road.
