U.S. Route 90orU.S. Highway 90(US 90) is an east–west majorUnited States highwayin theSouthern United States.Despite the "0" in its route number, US 90 never was a full coast-to-coast route. It generally travels nearInterstate 10(I-10) and passes through the southern states ofTexas,Louisiana,Mississippi,Alabama,andFlorida.US 90 also includes part of theDeSoto TrailbetweenTallahasseeandLake City, Florida.

With the exception of a short-lived northward extension toUS 62/US 180nearPine Springs, Texas,that existed for less than one year, its western terminus has always been atVan Horn, Texas;this is an intersection withI-10 Business(formerlyUS 80) just north of an interchange withI-10.Its eastern terminus is atFlorida State Road A1AinJacksonville Beach, Florida,three blocks from theAtlantic Ocean.

On August 29, 2005, a number of the highway's bridges inMississippiandLouisianawere destroyed or damaged due toHurricane Katrina,including theBay St. Louis Bridge,theBiloxi Bay Bridge,and theFort Pike Bridgewhich have been replaced.

Texas

US 90 south ofVan Horn

US 90 begins at anintersectionwithBL I-10andSH 54in downtownVan Horn.It then heads south-southeast towardsMarfa,where the route begins to head generally east. The route is mostly two lanes west ofUvalde.At this point, it becomes a four-lane surface road until it reaches westernBexar Countywhere it becomes afreeway,joiningI-10inDowntown San Antonio.Thisconcurrencywith I-10 continues intermittently into westernHouston,where US 90 follows the Katy Freeway. The section of US 90 that is multiplexed with I-10 through Houston is the only section of the route that is unsigned. In eastern Houston, US 90 splits from I-10 and heads northeast towardsLiberty,eventually traveling throughdowntown Beaumontwhere it rejoins I-10 for the rest of its routing through Texas.

The speed limit on US 90 between Van Horn andDel Riois mainly 75 miles per hour (121 km/h). Beginning atSeguin,US 90 Alternatesplits 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 inHarris Countywas completed along a new routing for US 90; that portion was designated the Crosby Freeway. This segment traveled from just insideBeltway 8to east of the town ofCrosby.Construction began in 2006 to extend the freeway westward to the intersection of I-10 (East Freeway) and theI-610 (East Loop).^[2]On January 24, 2011, the new extension officially opened. Due to lack of funds, overpasses were not built overGreens Bayouand over future Purple Sage Road, leaving traffic to briefly exit to the frontage roads before rejoining the freeway.^[3]

Louisiana

Entering Louisiana from the west, US 90 andI-10travel side by side throughLake CharlestoLafayette.In Lafayette, US 90 and I-10 part ways: I-10 proceeds east toBaton Rouge,while US 90 takes a southern turn and passes throughNew Iberia,Franklin,Morgan City,and theHouma – Bayou Cane – Thibodaux metropolitan areabefore reachingNew Orleans.The four-laning of US 90 was pushed in the 1990s by formerState Senator Carl W. Bauerthrough his role as the chairman of the Governor'sInterstate 49Task Force while also a member of the Greater LafayetteChamber of Commerce.^[4]

The portion of US 90 from Lafayette to New Orleans is designated to become the corridor forI-49.In New Orleans, US 90 again meets up with I-10, and the two highways follow a similar path into Mississippi.

The description of US 90's route in Mississippi is explained in State Code § 65-3-3.

Prior to Hurricane Katrina, Mississippi's portion of US 90 was entirely four-lanes 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.

BeforeHurricane Camillein 1969, the 26-mile (42 km) stretch of US 90 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 theGulf of Mexicoon its south side and lovely mansions — someantebellum— on its north. The median featured many old, stately oak trees, a good number of which survived the storm.

Many segments and important bridges were heavily damaged or destroyed by Hurricane Katrina in 2005. With the opening of two lanes of the Biloxi Bay Bridge on November 1, 2007,^[5]the entire route is now restored. Reconstruction projects continue on much of the highway and lane closures are common. Substantial completion of all US 90 Katrina-related road work in this state was scheduled to have been completed by now.^[when?]

'US Highway 90 Project History' recounts in some detail this roadway's colorful past in Mississippi, dating back to the early 20th century when it was part of theOld Spanish Trail.The pdf document is available at the 'Project Updates' page of theMississippi Department of Transportation's website ( gomdot ).

US 90/Alabama State Route 188concurrency ends inGrand Bay.

US 90, internally designated by theAlabama Department of TransportationasState Route 16(SR 16), is a major east–weststate highwayacross the southern part of theU.S. stateofAlabama.US 90/SR 16 crosses the extreme southern part of the state, covering approximately 77 miles (124 km). The routes pass through Baldwin County before entering the city ofMobilewhere it gains awrong way concurrencywith US 98. and later joins US Truck Route 98, briefly also overlappingInterstate 165.The portion of US 90 that crosses Mobile Bay is locally referred to as the "Causeway".With the completion ofI-10,US 90/SR 16 serves primarily as a local route connecting the towns along its path.

As it enters the Sunshine State, US 90 shifts south towardsPensacolawhileUS 90 Alternatestays to the north of the city. This stretch of highway is also known as Nine Mile Road. AfterHurricane Ivandestroyed the I-10 Bridge in Northwest Florida, motorists waited as long as two hours to cross the Escambia bridge betweenSanta RosaandEscambiacounties.

The highway's route continues to the north of I-10 as a two-lane highway through most of the sparsely-populated inland areas of thepanhandle,becoming four lanes through and near several towns. InGadsden County,US 90 cuts to the southeast toward downtownTallahassee,where it passes the north entrance ofFlorida State Universityand expands to six lanes until its intersection withUS 27.The portion of the highway that extends throughMidwayhas been designated as theAlfred Lawson, Jr.Highway. Continuing east, the highway is a two-lane road north of I-10 along the rest of its route, except as it turns to the south to pass throughLake CityatI-75.After going through theOsceola National Forest,it passesI-295heading intoJacksonville,becoming four lanes through the industrialized west side as Beaver Street, and through downtown as Union Street. It crosses theSt. Johns Riveron theMain Street Bridgeand continues east asBeach Boulevardto its terminus atFlorida State Road A1AinJacksonville Beach.

US 90 passes through thecounty seatsof 15 counties on its course in Florida, and is never more than 6 miles (9.7 km) from I-10 throughout the state. The highway's hiddenstate roaddesignation is primarilyFlorida State Road 10(Florida State Road 10Ain Pensacola), but along Beach Boulevard in Jacksonville it becomesFlorida State Road 212.

The speed limit is 55 mph (89 km/h) for all rural points west ofMonticello, Florida,and it is 60 mph (97 km/h) on all rural points beginning in Madison County toGlen St. Mary.

History

Hurricane Katrina

The US 90 bridge betweenBay Saint Louis, Mississippi,andPass Christian, Mississippi,as well as the bridge betweenBiloxi, Mississippi,andOcean Springs, Mississippi,were destroyed byHurricane Katrinain August 2005. During the storm, the St. Louis Bay bridge was under water and destroyed. Portions of US 90 were damaged along theBattleship Parkwayon Mobile Bay in Baldwin County, Alabama. Sections of the highway inHarrison County, Mississippi,including other bridges and much of the roadbed, were damaged or destroyed. Both theRigolets Bridgeand the Chef Menteur Bridge acrossChef Menteur PassinNew Orleans Eastwere damaged, but have since been reopened. Some sections of the highway inNew Orleanswere impassable under flood waters for weeks due to the general flooding of that city; seeEffect of Hurricane Katrina on New Orleans.TheCrescent City Connectionbridge over theMississippi Riverin Sector 49, also known asUS 90 Business,remained intact and was the only usable route out of that city in the immediate aftermath of the storm until the section of Leake Avenue/River Road between New Orleans andMetairiewas able to be cleared of heavy debris, but was blocked off byJefferson ParishandGretnalaw enforcement officials in a politically controversial move to prevent the looting and general anarchy from spreading to the relatively intact west bank of the Mississippi River.

New US 90 bridge between Biloxi and Ocean Springs under construction

In mid-2006, construction began on the replacement for the Bay St. Louis bridge.^[6]It was completed on January 4, 2008, and includes four traffic lanes plus emergency shoulders and a bicycle/pedestrian path. It also stands 85 feet (26 m) high at its highest point. Two-way traffic resumed on the eastbound lanes of the bridge on May 17, 2007, after an afternoon ceremony,^[7]effectively ending the temporary ferry service. The remaining half of the bridge opened to traffic on January 4, 2008.^[8]

On June 6, 2006, a $338.6 million contract was let for the Biloxi-Ocean Springs replacement. The bridge will be 95 feet (29 m) tall at its highest point and will carry six traffic lanes, 8-foot-wide (2.4 m) inside and 10-foot-wide (3.0 m) outside shoulders, and a bicycle/pedestrian path. To many area residents' and leaders' delight, the bridge's westbound lanes opened to two-way traffic after a ceremony and parade on November 1, 2007, two weeks ahead of schedule.^[9]Total bridge construction, including the opening of all six lanes of traffic, was scheduled to be completed by April 2008.^[10]

After it was closed due to storm damage, the 1929 vintage bridge carrying US 90 overChef Menteur Passwas repaired and opened to traffic on August 11, 2006.
