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.
U.S. Route 90 in Florida
After the eastern terminus of State Road 296 at Perry Avenue, the name of the road changes to "Scenic Highway," becoming an official Florida Scenic Highway known as the Pensacola Scenic Bluffs Highway. It narrows down from four lanes to two lanes between Chipley Avenue and Strong Street, and it turns north where it runs along the west side of Escambia Bay. Along the way, it frequently encounters the CSX P&A Subdivision, a former Louisville and Nashville Railroad line that carried Amtrak's Sunset Limited from 1993 until 2005 when Hurricane Katrina truncated the line to New Orleans. The road moves closer to the tracks near Magnolia Point just south of Hyde Park Road. Most of the area along this segment is residential, and those that aren't normally tend to consist of either parkland or merely open space.
