"Problematic" = Relatively large tunnel size needed for two pickups to pass due to lack of bedrock, needed strengthening for sandy soil, complicated drainage issues (and possible pumping needed) for high water table, mobilizing a boring machine since cut & cover wouldn't most likely be allowed across turnpike, etc., etc.
Please note that I did not say... "it can't be done." 
Although different environmental conditions, some of the same issues of a tunnel versus a bridge...are covered in this article.

Just setting the record straight.  |
"I am thinking that tunneling under a divided 4 lane turnpike, would be much more problematic (and expensive?),
plus it would be hard to make it large enough to get a pickup sized vehicle from one side to the other...which I believe will be something they will want with this crossing. "
OK, I took a little poetic license, my bad. But I wouldn't characterize it as "not even close" to what was said either. OMG, after the shock of agreeing with each other 4 or 5 times in a row, we are back to reality
