Beginning at Seguin, US 90 Alternate splits from US 90 and travels parallel to the south, rejoining the main route in northeast Houston. In 1991, the construction on a four- to six-lane freeway northeast of Houston in Harris County was completed along a new routing for US 90; that portion was designated the Crosby Freeway. This segment traveled from just inside Beltway 8 to east of the town of Crosby. Construction began in 2006 to extend the freeway westward to the intersection of I-10 (East Freeway) and the I-610 (East Loop). On January 24, 2011, the new extension officially opened. Due to lack of funds, overpasses were not built over Greens Bayou and over future Purple Sage Road, leaving traffic to briefly exit to the frontage roads before rejoining the freeway. Entering Louisiana from the west, US 90 and I-10 travel side by side through Lake Charles to Lafayette. In Lafayette, US 90 and I-10 part ways: I-10 proceeds east to Baton Rouge, while US 90 takes a southern turn and passes through New Iberia, Franklin, Morgan City, and the Houma – Bayou Cane – Thibodaux metropolitan area before reaching New Orleans. The four-laning of US 90 was pushed in the 1990s by former State Senator Carl W. Bauer through his role as the chairman of the Governor’s Interstate 49 Task Force while also a member of the Greater Lafayette Chamber of Commerce. The portion of US 90 from Lafayette to New Orleans is designated to become the corridor for I-49. In New Orleans, US 90 again meets up with I-10, and the two highways follow a similar path into Mississippi. Prior to Hurricane Katrina, Mississippi's portion of US 90 was entirely four-laned except for a very short segment at the state's west end leading to the old Pearl River Bridge into Louisiana. That segment of old highway is obviated for most purposes by an extension of the four-lane roadway from its split with US 90 to I-10 just east of the much newer Pearl Bridge. Before Hurricane Camille in 1969, the stretch of US 90 traveling from the Bay St. Louis Bridge at the west end to the Biloxi Bay Bridge at the east was one of the most scenic roadways in the south, offering beautiful views of the Gulf of Mexico on its south side and lovely mansions — some antebellum — on its north.
