I found the ride to be very doable. The only time I felt it wasn't safe was Marine Road when leaving Creve Coeur Park. It's a long steep uphill without a spot to, even, stop, let alone pull over to the side. There's too great a drop off.
Fortunately, there's an alternative that you can see on the above link. I didn't know about it at the time -- wish I had.
There are times you will have to be on the road with traffic, but I didn't find it too bad, but some may not feel comfortable.
