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 Business (New Orleans, Louisiana)
From the west, US 90 Bus. begins at a modified trumpet interchange with US 90 in a sparsely developed area of Jefferson Parish surrounded by the suburban city of Westwego, Bayou Segnette State Park, and an industrial area formerly known as Avondale Shipyard. Mainline US 90 connects with Boutte to the west and the Huey P. Long Bridge across the Mississippi River to the east (geographically north). Due to the proximity of the BNSF/Union Pacific Railroad overpass on eastbound US 90, the ramp from westbound US 90 Bus. travels in an indirect fashion and intersects an eastbound ramp at grade at a four-way stop. As a result, a significant amount of local traffic circumvents this movement by turning onto Nine Mile Point Road toward a signalized intersection with US 90 that features a protected no-stop turn lane.
