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

964-999

KEY
Number: Self-explanatory. Listings shaded in BLUE are active. All numbers below 400 were originally assigned to other routes.
Year(s): Start date for this number and end date if decommissioned; may not be exact. Only years are used; see Jason Hancock's site for exact dates if available. Those specifically involved in the Second Great Decommissioning of 2003 are shaded in gray; those not shaded with a 2003 date were turned over in separate agreements. Years are based on when a bypass segment opened, and then the last year the number appeared on the 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/existed afterward.
Old/Co.: Its number when it was signed, _not_ the route the number was originally used for/county it's in, in the case of the non-9xxs.
Length: Self-explanatory. Most numbers are courtesy Jason Hancock's research into the "Primary Road Sufficiency Log". Some lengths of road segments created after 2002 are measured on Google Maps if possible.
Proof of life: Image(s) from at least one of the following: official state maps (if visible) and 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; more than a decade later, the Iowa DOT put online most if not all of its post-1969 (or so) official primary route descriptions. In those cases, maps without the numbers may be provided to show where the route was.
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.

Thanks to Alex Latham for spotting 20th-century traffic books online and pointing out some of their secrets.

965	1976-1980	US 52 Winneshiek	3.3	Jason Hancock's research: "US 52 intersects 3 times" Bypassed segments at W34 and through Burr Oak
*965*	1985 (-1990) (-1994) (-spring 2003) (-July 1, 2003)	US 218 Linn/ Johnson	17.8 (1985) 16.3 (1990) 13.79 (2003)	2001 Originally extended up to US 30, was 218 (rerouted after IC bypass done), 6th St. north of there and 16th Ave. became 941 in 1981; now only extends to 76th Ave. C.R. Gazette reported part N of F12 taken over by Cedar Rapids in spring 2003	Perhaps most famous "secret" road; poss. first signed Broken after N. Liberty's segments turned over until 2003

Jason Hancock: "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."	Football players have runs longer than this road, just west of Farley

UNUSED NUMBERS (past and present): 900-902, 905-911

Old 34 west of Ottumwa, old IA 150 south of Fayette, the pre-2003 route of IA 982, and old US 34 east of Chariton were renumbered in 1967 "due to a conflict with the accident coding procedures of the Department of Public Safety." Aside from 988, no number above 986 was recycled, even if it was gone by 1963.
