KEY
Number: Self-explanatory.
Year(s): Start date for this number and end date if decommissioned;
may not be exact. If possible, year is last year before removal
from the DOT map (for example, 392 was on 2000 but not 2001, meaning
decommissioning in 2000; 431 not on 2002 map, meaning gone in
2001). Year in parentheses, ex. (-1994), means part but not all
of the route was decommissioned that year and part still exists.
Old/Co.: Its number when it was signed, _not_ the route the number
was originally used for/county it's in.
Length: Self-explanatory. Most numbers are courtesy Jason Hancock's
research into the "Primary Road Sufficiency Log".
On list (Y/N/D): Y: Died as a result of the Second Great Decommissioning
(July 1, 2003). N: Still alive. D: Decommissioned before list
issued or in separate transaction as noted in county supervisors'
minutes.
Proof of life: Image(s) from at least one of the following: official
state maps (if visible) and most recent PDF state and/or county
maps from DOT site. State clips are from the map dated 1/1/00
and are more pixelated; county clips are from maps dated 1/1/01
unless noted. Jason Hancock did some additional research
in May 2002; if there are no images his research is credited as
proof.
NOTE: Images are severely trimmed to show number and part
or all of the route. Images are at a large size because otherwise
sometimes you can't even see it. Download
the county maps from the DOT's site for context.
Other notes: Self-explanatory. If you can help us fill out the
holes and question marks please send me an e-mail.

"From eastbound 20, there is a turnoff for Farley's industrial park at the same time you see the first BGS for the Y13 interchange. After turning left, there is a sharp turn to the right, and once you're there you'll come to a DOT-style Farley city limit sign right next to the Sinclair station. The pavement changes at that point, and that's where 968 ends." |
