Regarding tagging highway=motorway or highway=trunk my take is the 
documentation is a bit ambiguous. I've posted the paragraph here. See 'In the 
less usual case ... along the same carriageway use a single way ...'.

I do not see a barrier using BING nor Mapbox Satellite.  However, TIGER 2014 
shows as a dual carriageway. Umm ... what to do? Follow TIGER? Or remove the 
FIXME and do nothing more?

>From the wiki:
'A motorway is normally represented by a series two parallel ways, one for each 
carriageway<http://en.wikipedia.org/wiki/carriageway> tagged with 
highway=motorway. These ways should all point direction of travel and be tagged 
with oneway=yes. In the less usual case of a motorway where traffic travels in 
both directions along the same carriageway use a single way and tag it with 
oneway=no. '

If there is actually a barrier in the middle that is not visible in Bing, then 
it should split into two separate one lane ways. Not sure I'd hang a motorway 
tag on it though as that requires a minimum of two lanes in each direction.

While mapping a FIXME in the US this situation came up: WAY ID 8822153. The

see this is one long stretch of highway=motorway. What is the thought on this?
it looks like it is divided by a barrier but single lane each way.
it would be good to verify the presence of the barrier. i think
a motorway designation is borderline given the single lane, but
a trunk would be about right. given verification of the barrier,
dual carriageway would be correct.
