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.

Continuing southeast, the highway remains a two-lane road north of I-10 as it passes by Suwannee River State Park, where it encounters the east end of the former ROW that used the Hillman Bridge, the western terminus of County Road 132 which is a direct route to Suwannee Springs, and the unincorporated community of Ellaville. The CSX line previously used by the Sunset Limited hugs the side of the road once again, this time on the north side. After passing through Falmouth, US 90 has another parclo interchange with I-10 at Exit 275, and goes south of I-10 once again. East of there, the road is named Howard Street.
