I think SR 102 continues west to the airport.
Why is SR 109 split in two? The overlap with SR 115
is signed 'to', and I know similar overlaps are included in TM. If I'm not mistaken, there's actually been a reconfiguration so both directions of SR 109 now stay on the frontage road.
Does SR 112 actually continue west of FL953_N?
SR 114 is signed (at least on I-95). Waypoints are FraSt (if we're counting interchange-related stubs like that), I-95, and Blvd.
Why is SR 267 split in two?
SR 405 is signed east from US1_S to
the end at the JFK Space Center.
SR 414 has new interchanges between FL434 and I-4: GatDr, MaiSumBlvd, and KelRd (Lake Destiny Road will no longer have any direct access when construction is done). HopeRd should be WymRd. There's also a new exit 4B at Marden Road.
SR 419/434: GarAve should be moved west to TusRd.
SR 423: CurSt -> ChuSt, WyhRd -> WymRd
SR 426: move OakHillDr west to WinSprBlvd?
SR 436: the south end is north of CargoRd at the canal bridges.
SR 482: as with other similar routes that end at interchanges with nearby roads (e.g. SR 421), the route extends west of I-4 to TurLakeRd.
SR 524 continues east to SR 528.
SR 526: BurAve -> BumAve
SR 527: OraAve -> LakeviewSt or GarAve or something that isn't actually SR 527
SR 536: signs continue west of I-4 to the WDW property line (marked on OSM)
SR 551: GolRdExt -> OldGolRd
SR 586, SR 590, SR 686, SR 688: add CR501?
SR 594 extends west to the eastbound end of I-175.
US 17/92: add CR580 in Haines City, CR54 -> RonReaPkwy, CR535 -> HamBroRd, CR531 -> PleHillRd (neither CR 535 nor CR 531 is signed or recognized by the county), US17/92Trk_S -> FL423, FL414/17Trk -> FL414 (these are much better signed than the truck routes), DirDr -> CR4162, SaxBlvd -> CR4146
US 17/92/441: CR527A -> LanRd
US 17: move KatSt one block north to CR4053
US 27: add CR17_HaiCity, RonReaPwky -> RonReaPkwy, add CROld50 in Minneola
US 192: AvaRd -> CR545_N, CR545 -> CR545_S, KisParkRd -> OCanCRd (to match US 441)
US 192/441: CR523_N -> CR523
US 441: add CR437_N and CR437_S just south of SR 429, CR452 -> LakeEusDr, CR44_E -> CR44LegA, CR44_W -> CR44
US 17/92 Truck (Orlando): WyhRd -> WymRd_S, HopeRd -> WymRd_N
