Hi abclop99, 
I found the following discussion: 
https://help.openstreetmap.org/questions/60200/what-barrier-type-should-be-uses-for-cones-and-signs-on-the-road
The suggested solution by keithonearth seems sound. I added the tag barrier=cones. This is not an official barrier type and routing software will ignore it, but as the streets are tagged correctly this seems the best solution. 
Best, Jokobus
