A Comprehensive(?) Listing of the 900s - Page 4

970-999

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): Appears on DOT's "Routes Eligible for Transfer of Jurisdiction" list (12/27/00) or decommissioned before list issued.
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.
