U.S. Route 90
U.S. Route 90 (US 90) is an east–west United States highway. Despite the "0" in its route number, US 90 never was a full coast-to-coast route; it has always ended at Van Horn, Texas with the exception of a short-lived northward extension to US 62/US 180 near Pine Springs, Texas which lasted less than a year, and the signs on that segment were changed to Texas State Highway 54, traveling from Interstate 10 (I-10) at exit 140A and heading to its northern terminus at US 62/US 180.

The second segment begins in eastern Ponce De Leon at US 90 east of Main Street. The first name of this segment is Old US 90, and runs northeast of US 90 from there until it reaches Oak Grove Church Road, then turns southwest until it terminates at US 90 in rural western Holmes County. FDOT maps, however suggest that the route extends past Oak Grove Church Road, and runs along the P&A Subdivision until that railroad line runs parallel to the north side of US 90 more than halfway between Oak Grove Church Road and Valee Road. It's possible that this is an abandoned segment of the road.
County Road 10A also exists in two different segments in Jackson County, one in the Marianna area and the other in Sneads. The first one is Old Cottondale Road which begins at US 90 west of Marianna, beginning southeast from US 90, and then curving straight east and west just before the intersection with Heritage Road, only to curve southeast again at a power sub-station just before the intersection with Moneyham Road. CR 10A doesn't truly enter the city limits until it approaches the headquarters of Jackson County Transportation on the northwest corner of Sunrise Drive. After this intersection, the road passes by the Apostolic Life United United Pentecostal Church turns straight east and west again. A few blocks after this it encounters its one major intersection other than its termini, State Road 276(Pennsylvania Avenue) at a blinker light intersection. East of there, the road takes a dip into the woods and has one intersection with Edenfield Street before a fork in the road for a former segment named Milton Avenue, and then a connecting spur named Hanson Street. Four blocks after this, it encounters a three-way stop intersection with Orange Street and then one intersection with a residential street before it crosses the P&A Subdivision next to a dry river bed and ends at US 90.
