Although my preference would also be for the former, people will break
the ways midblock, for very good reasons. For example, recording a small
bridge in the middle of the block would entail splitting the way into
three--one for the bridge, and one on each end of it. Most likely, each
piece will still carry the full address range, even though the bridge
should have none and the range should be split. In Tampa, we also have
instances of streets transitioning from 4-lane undivided to 4-lane
divided ("dual carriageways") midblock.
Which raises another issue. The old TIGER files had a single way for
most of the dual carriageway major streets in our area. I have not
looked at the new 2009 TIGER files, but I suspect that they have similar
representations of these streets. When splitting these into two parallel
one-way routes, should both then carry the original addressing ranges,
or should one carry the odd address numbers and the other carry the even
address numbers?
