<p>Yes you can.... use a geogrid and float the road over the roots.

<p>Any engineer worth their salt would know of this and be able to
make it work. Key to the design is the coarse rock on the geogrid
(allows water in and gas out). <br>

suspect this situation is all too frequent for some members
of this forum: an infill development is given municipal
approval on the basis of an insufficient analysis of mature
tree retention. When upon closer scrutiny this analysis is
found to be lacking the role of the consulting arborist
(brought in at the 11<sup>th</sup> hour) is essentially to
fit a square peg into a round hole. In short, and without
getting into too many specifics, has anyone had experience
building a road over the roots of two mature sugar maples –
80-100 cm dbh (distance of road from base of trees is
1.2m!). And, yes, the trees must remain. I’m sure many of
you can relate to my frustration.<o:p></o:p></span></p>
