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.

North of Cypress the road intersects the northern terminus of CR 275 (Church Street) and then turns straight east, and continues in this trajectory as it enters the Town of Grand Ridge where it becomes a four-lane divided highway again and intersects State Road 69 (Porter Avenue). US 90 remains a four lane divided highway well east of the town limits. Nearly halfway outside of Grand Ridge, it intersects County Road 69A, where a short segment of "Old U.S. Highway 90" can be found on the northeast corner which actually ends at US 90 between the two ends of Morgan Loop, as it curves to the southeast. An abandoned segment of this road used to end at Mohawk Trail. As it enters the Town of Sneads it instantly has an intersection with County Road 10A (Keevers Road), which leads to the Old Spanish Trail. Further in town, it takes a slight turn to the northeast where it becomes a four-lane undivided highway as it runs along part of Three Rivers State Park before it serves as the southern terminus of County Road 271 (River Road), which runs along the west coast of the Jim Woodruff Reservoir and through parts of the Apalachee Wildlife Management Area, and then has an intersection with County Road 286 (Gloster Avenue) which leads to the last interchange with I-10 in the county, and then into Calhoun County. More than a block later, it narrows back down to two lanes. After curving to the southeast momentarily, CR 10A and the Old Spanish Trail reunite with US 90 before the road leaves town, and the road turns straight east once again. This alignment ends as it curves back to the southeast and approaches the last landmark along US 90 in Jackson County, the Apalachee Correctional Institute, a massive prison farm. East of that point, the road begins to cross the Victory Bridge over the floodplains of the Apalachicola River, but does not cross the river directly just yet, until it curves back to the east. A power line right of way and one last local intersection can be found before the road and bridge finally crosses the river itself between the Jim Woodruff Dam and the Old Victory Bridge, where US 90 finally leaves what is historically considered "West Florida."
