==Route description==
{{Unsourced section|date=December 2023}}
I-10 enters Louisiana at the state's southwestern corner from [[Orange, Texas|Orange]], [[Texas]], in a concurrency with [[U.S. Route 90 in Louisiana|US Route 90]] (US 90), which leaves the freeway at the first exit. The two routes closely parallel each other through much of the state. The first community I-10 approaches in the state is [[Vinton, Louisiana]]. Between [[Sulphur, Louisiana|Sulphur]] and [[Lake Charles, Louisiana|Lake Charles]] there is an interchange with [[Interstate 210 (Louisiana)|I-210]]. I-10 crosses the [[Calcasieu River Bridge]] into Lake Charles, passing north of the center of town, before meeting the western end of I-210. Between Lake Charles and [[Lafayette, Louisiana|Lafayette]], I-10 bypasses several small towns including [[Iowa, Louisiana|Iowa]], [[Welsh, Louisiana|Welsh]], [[Jennings, Louisiana|Jennings]], and [[Crowley, Louisiana|Crowley]]. In Lafayette, I-10 meets the current southern terminus of [[Interstate 49 in Louisiana|I-49]], leaving northwest out of the city and passing by the community of [[Breaux Bridge, Louisiana|Breaux Bridge]].
From Lafayette, the highway heads east-northeast toward Baton Rouge via the [[Atchafalaya Basin Bridge|Atchafalaya Swamp Freeway]], an {{convert|18.2|mi|km|adj=on}} bridge across the [[Atchafalaya Basin|Atchafalaya River and its accompanying swamp]]. Between the two cities, I-10 parallels [[U.S. Route 190|US 190]], from [[Opelousas, Louisiana|Opelousas]] to Baton Rouge. This route has signs and is designated as an alternate I-10 bypass that runs from I-10/I-49 north to US 190 (exit 19B at Opelousas) then east across to Baton Rouge and back down to I-10 via I-110 south. Traffic can be diverted both ways along this route should there be the necessity to close I-10 across the Atchafalaya Swamp Freeway and is also used as a hurricane evacuation route.
[[File:The I-10, running west of New Orleans.jpg|thumb|left|I-10 running west of New Orleans, spanning the Bonnet Carre Spillway at Lake Pontchartrain]]
In the capital of Baton Rouge, US 190 continues east alongside [[Interstate 12|I-12]] to [[Hammond, Louisiana|Hammond]] and [[Slidell, Louisiana|Slidell]] while I-10 turns southeastward and parallels [[U.S. Route 61|US 61]] ([[Airline Highway]]) to [[New Orleans]]. In the Crescent City, I-10 rejoins US 90 (and later [[U.S. Route 11 in Louisiana|US 11]]) as it heads toward [[Slidell, Louisiana|Slidell]]. In Slidell, US 11 continues northeastward toward [[Hattiesburg, Mississippi]] while I-10 and US 90 turn eastward toward coastal [[Mississippi]].
Major bridges on I-10 in Louisiana include the [[Interstate 10 bridge (Sabine River)|Sabine River Bridge]] (c. 1952, replaced 2003), the [[Lake Charles I-10 Bridge]] (1952), the Atchafalaya Swamp Freeway (1973), the [[Horace Wilkinson Bridge]] over the [[Mississippi River]] (1968), the [[I-10 Bonnet Carré Spillway Bridge|Bonnet Carré Spillway Bridge]] (c. 1972), the [[I-10 High Rise Bridge|Industrial Canal Bridge]] (c. 1960), [[I-10 Twin Span Bridge|Frank Davis "Naturally N'Awlins" Memorial Bridge]] (1965, replaced 2010), and the [[Interstate 10 bridge (Pearl River)|Pearl River Bridge]] (c. 1970).

I-12, serving as a bypass of New Orleans around the north side of Lake Pontchartrain, was not added until October 17, 1957. At the time, I-10 and [[Interstate 59 in Louisiana|I-59]] split in eastern New Orleans, with I-59 following present I-10 and I-10 following the US 90 corridor into Mississippi, and so I-12 only ran to I-59 north of Slidell.<ref name="October 1957 Interstates">{{cite map |author = Public Roads Administration |url = https://commons.wikimedia.org/wiki/File:Interstate_Highway_plan_October_17,_1957_reverse_colors.jpg |title = Routes To Be Added to the National System of Interstate and Defense Highways |date = October 17, 1957 |scale = Scale not given |___location = Washington, DC |publisher = Public Roads Administration |access-date = August 15, 2012 |via = Wikimedia Commons |archive-date = October 22, 2016 |archive-url = https://web.archive.org/web/20161022094425/https://commons.wikimedia.org/wiki/File:Interstate_Highway_plan_October_17,_1957_reverse_colors.jpg |url-status = live }}</ref> By the mid-1960s, the routes had been realigned to their current configuration, with I-12 and I-59 both ending at I-10 near Slidell.<ref>{{cite map |author = Public Roads Administration |url = https://commons.wikimedia.org/wiki/File:Interstate_Highway_status_unknown_date.jpg |title = The National System of Interstate and Defense Highways |year = c. 1963 |scale = Scale not given |___location = Washington, DC |publisher = Public Roads Administration |access-date = August 15, 2012 |via = Wikimedia Commons |archive-date = November 9, 2012 |archive-url = https://web.archive.org/web/20121109213025/http://commons.wikimedia.org/wiki/File:Interstate_Highway_status_unknown_date.jpg |url-status = live }}</ref>
Construction of the Interstate Highway System in Louisiana began in 1957.<ref name="S-T 8-7-57">{{cite news |title = Federal funds for roads |newspaper = State-Times |___location = Baton Rouge |date = August 7, 1957 |page = 8A }}</ref> Early I-10 contracts were done under the route designation LA 3027. Much of the early construction on the I-10 corridor was concentrated on relieving traffic problems in urban centers. Several such projects were already underway and were incorporated into the route of I-10 during construction, such as the [[Pontchartrain Expressway]] in New Orleans. In addition, the two major bridges on the route in [[Calcasieu Parish, Louisiana|Calcasieu Parish]] between the Texas state line and Lake Charles were built for US 90 in the early 1950s and retrofitted for I-10 traffic. Sections of I-10 through rural areas and/or those sections already served adequately by existing highways, such as Airline Highway (US 61) between Baton Rouge and New Orleans, were constructed later in the program. By the spring of 1975, the entire route of I-10 had been opened across Louisiana except for a problem {{convert|5.5|mi|km|adj=on}} section between [[Gonzales, Louisiana|Gonzales]] and [[Sorrento, Louisiana|Sorrento]] that was not completed for another three years.

Reconstruction of the portion at the I-610 Split vicinity was undertaken in the late 1990s. Also in the late 1990s, further work was done on the expressway as two ramps were constructed, connecting West I-10 to West Business U.S. 90 and westbound Claiborne Avenue (West US 90), replacing an earlier, more dangerous ramp. The direct ramp from 90B East to I-10 East was completed by 1989.<ref name="T-P 3-8-89">{{cite news |last=Philbin |first=Walt |title=I-10's Deadly Ramps a Worry from the Start |newspaper=The Times-Picayune |issn=1055-3053 |___location=New Orleans |date=March 8, 1989 |page=A1}}</ref>
In the aftermath of [[Hurricane Katrina]], the I-10 Twin Span Bridge, a portion of I-10 between New Orleans and Slidell, spanning the eastern end of Lake Pontchartrain, was severely damaged, causing a break in I-10 at that point. Unlike the [[Escambia Bay Bridge]] (east of [[Pensacola, Florida|Pensacola]], [[Florida]] and damaged by [[Hurricane Ivan]]), which is a major artery, I-12 is available to bypass New Orleans. Taking I-12 to the [[Lake Pontchartrain Causeway]] allowed entry and exit to and from the [[Greater New Orleans]] area from the East. On October 14, 2005, at 3:00 pm, the eastbound span was reopened to two way traffic.
