U.S. Route 90


U.S. Route 90 or U.S. Highway 90 is an east–west major United States highway in the Southern United States. Despite the "0" in its route number, US 90 never was a full coast-to-coast route. With the exception of a short-lived northward extension to US 62/US 180 near Pine Springs, Texas that existed for less than one year, its western terminus has always been at Van Horn, Texas; currently, this is an intersection with Interstate 10 Business just north of an interchange with Interstate 10. Its eastern terminus is at Florida State Road A1A in Jacksonville Beach, Florida, three blocks from the Atlantic Ocean.
On August 29, 2005, a number of the highway's bridges in Mississippi and Louisiana were destroyed or damaged due to Hurricane Katrina, including the Bay St. Louis Bridge, the Biloxi Bay Bridge, and the Fort Pike Bridge. US 90 has seven exits on I-10 in the State of Florida. It also includes part of the between Tallahassee and Lake City, Florida.

Route description

Texas

US 90 begins at an intersection with BL I-10 and SH 54 in downtown Van Horn. It then heads south-southeast towards Marfa, where the route begins to head generally east. The route is mostly two lanes west of Uvalde. At this point, it becomes a four-lane surface road until it reaches western Bexar County where it becomes a freeway, joining I-10 in Downtown San Antonio. This concurrency with I-10 continues intermittently into western Houston, 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 towards Liberty, eventually traveling through downtown Beaumont where it rejoins I-10 for the rest of its routing through Texas.
The speed limit on US 90 between Van Horn and Del Rio is mainly. 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 and the I-610. 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.

Louisiana

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.

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. 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, the entire route is now restored. However, reconstruction projects continue on much of the highway and lane closures are not rare. Substantial completion of all US 90 Katrina-related road work in this state was scheduled to have been completed by now.
'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 the Old Spanish Trail. The pdf document is available at the 'Project Updates' page of the Mississippi Department of Transportation's website.

Alabama

US 90, internally designated by the Alabama Department of Transportation as State Route 16, is a major east–west state highway across the southern part of the U.S. state of Alabama. US 90/SR 16 crosses the extreme southern part of the state, covering approximately. The routes pass through the city of Mobile and its suburbs before entering Baldwin County. With the completion of I-10, US 90/SR 16 serves primarily as a local route connecting the towns along its path.

Florida

As it enters the Sunshine State, US 90 shifts south towards Pensacola while US 90 Alternate stays to the north of the city. This stretch of highway is also known as Nine Mile Road. After Hurricane Ivan destroyed the I-10 Bridge in Northwest Florida, motorists waited as long as two hours to cross the Escambia bridge between Santa Rosa and Escambia counties.
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 the panhandle, becoming four lanes through and near several towns. In Gadsden County, US 90 cuts to the southeast toward downtown Tallahassee, where it passes the north entrance of Florida State University and expands to six lanes until its intersection with US 27. The portion of the highway that extends through Midway has been designated as the Alfred 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 through Lake City at I-75. After going through the Osceola National Forest, it passes I-295 heading into Jacksonville, becoming four lanes through the industrialized west side as Beaver Street, and through downtown as Union Street. It crosses the St. Johns River on the Main Street Bridge and continues east as Beach Boulevard to its terminus at Florida State Road A1A in Jacksonville Beach.
US 90 passes through the county seats of 15 counties on its course in Florida, and is never more than from I-10 throughout the state. The highway's hidden state road designation is primarily Florida State Road 10, but along Beach Boulevard in Jacksonville it becomes Florida State Road 212.
The speed limit is for all rural points west of Monticello, Florida, and it is on all rural points beginning in Madison County to Glen St. Mary.

History

Hurricane Katrina

The US 90 bridge between Bay Saint Louis, Mississippi and Pass Christian, Mississippi, as well as the bridge between Biloxi, Mississippi and Ocean Springs, Mississippi were destroyed by Hurricane Katrina in August 2005. During the storm, the St. Louis Bay bridge was under water and destroyed. Portions of US 90 were damaged along the Battleship Parkway on Mobile Bay in Baldwin County, Alabama. Sections of the highway in Harrison County, Mississippi, including other bridges and much of the roadbed, were damaged or destroyed. Both the Rigolets Bridge and the Chef Menteur Bridge across Chef Menteur Pass in New Orleans East were damaged, but have since been reopened. Some sections of the highway in New Orleans were impassable under flood waters for weeks due to the general flooding of that city; see Effect of Hurricane Katrina on New Orleans. The Crescent City Connection bridge over the Mississippi River in Sector 49, also known as US 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 and Metairie was able to be cleared of heavy debris, but was blocked off by Jefferson Parish and Gretna law 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.
In mid-2006, construction began on the replacement for the Bay St. Louis bridge. It was completed on January 4, 2008 and includes four traffic lanes plus emergency shoulders and a bicycle/pedestrian path. It also stands high at its highest point. Two-way traffic resumed on the eastbound lanes of the bridge on May 17, 2007 after an afternoon ceremony, effectively ending the temporary ferry service. The remaining half of the bridge opened to traffic on January 4, 2008.
On June 6, 2006, a $338.6 million contract was let for the Biloxi-Ocean Springs replacement. The bridge will be tall at its highest point and will carry six traffic lanes, inside and 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. Total bridge construction, including the opening of all six lanes of traffic, was scheduled to be completed by April 2008.
After it was closed due to storm damage, the 1929 vintage bridge carrying US 90 over Chef Menteur Pass was repaired and opened to traffic on August 11, 2006.

Florida State Road 1

The Florida State Road No. 1 is a historic road near Milton, Florida. It is located, roughly, in three sections east of Milton, parallel to U.S. 90, between Marquis Bayou and Harold. On June 23, 1994, it was added to the National Register of Historic Places.
