I-20 traverses the northern portion of the state, serving the [[metropolitan area]]s of [[Shreveport, Louisiana|Shreveport]]&ndash;[[Bossier City, Louisiana|Bossier City]] and [[Monroe, Louisiana|Monroe]], as well as the smaller cities of [[Minden, Louisiana|Minden]] and [[Ruston, Louisiana|Ruston]]. It entirely parallels the older [[U.S. Route 80 in Louisiana|U.S. Highway&nbsp;80]] (US&nbsp;80) corridor through Louisiana. The route is mirrored by [[Interstate 10 in Louisiana|I-10]], which traverses the southern portion of the state. The two are connected by [[Interstate 49 in Louisiana|I-49]], the state's major north&ndash;south [[Interstate Highway]]. ==Route description== ===Texas state line to Shreveport (Interstate 49)=== I-20 enters Louisiana about {{Convert|20|mi|km}} east of [[Marshall, Texas]], near [[Waskom, Texas|Waskom]]. I-20 passes through [[Greenwood, Louisiana|Greenwood]] to the north of town, where [[U.S. Route 80|US&nbsp;80]]/[[U.S. Route 79|US&nbsp;79]] serve as the main east–west highway. I-20 enters [[Shreveport, Louisiana|Shreveport]] about {{Convert|5|mi|km}} east of Greenwood. I-20 intersects [[Interstate 220 (Louisiana)|I-220]] (the north Shreveport bypass) and [[Louisiana Highway 3132]] (LA&nbsp;3132, the south Shreveport bypass) on the westside of the city. On the way to Downtown Shreveport, I-20 intersects [[U.S. Route 171|US&nbsp;171]] and serves as the current northern terminus of [[Interstate 49|I-49]]. ===Shreveport to Monroe=== As I-20 leaves Shreveport, it passes through [[Bossier City, Louisiana|Bossier City]] where it shares an overlap with [[U.S. Route 71|US&nbsp;71]]. I-20 passes north of [[Barksdale Air Force Base|Barksdale AFB]] where it intersects [[Interstate 220 (Louisiana)|I-220]] and heads east toward [[Monroe, Louisiana|Monroe]]. On its way to Monroe, I-20 traverses mainly rural, hilly terrain as it passes through the towns of; [[Minden, Louisiana|Minden]], [[Arcadia, Louisiana|Arcadia]], [[Grambling, Louisiana|Grambling]], [[Ruston, Louisiana|Ruston]] (where it intersects [[U.S. Route 167|US&nbsp;167]]), and [[West Monroe, Louisiana|West Monroe]]. ===Monroe to Mississippi state line=== I-20 passes through [[Monroe, Louisiana|Monroe]], where it intersects [[U.S. Route 165|US&nbsp;165]]. East of Monroe, I-20 enters flatter terrain as it passes through [[Rayville, Louisiana|Rayville]], [[Delhi, Louisiana|Delhi]], and [[Tallulah, Louisiana|Tallulah]]. About {{Convert|15|mi|km}} east of Tallulah, I-20 crosses over the [[Mississippi River]] into [[Vicksburg, Mississippi]]. {{-}} ==Exit list== {{LAinttop|exit|length_ref=<ref name="LRS 2016"/>}} {{jctint|exit |river=[[Louisiana]]–[[Texas]] line |lspan=2 |mile=0.000 |road={{jct|state=TX|I|20|dir1=west|city1=Dallas}} |notes=Continuation into [[Texas]] }} {{jctrestarea|exit |state=LA |type=incomplete |mile=0.039 |restarea=Texas Travel Information Center (westbound only) }} {{jctrestarea|exit |state=LA |parish=Caddo |pspan=16 |location=Greenwood |lspan=3 |type=incomplete |mile=2.292 |mile2=2.928 |restarea=Greenwood Rest Area & Visitor's Center (eastbound only) }} {{LAint|exit |mile=3.592 |mile2=4.085 |exit=3 |road={{jct|state=LA|US|79|dir1=south|location1=[[Carthage, Texas]]}}<br/>{{jct|state=LA|LA|169|city1=Mooringsport}} |notes= }} {{LAint|exit |mile=5.368 |mile2=5.894 |exit=5 |road={{jct|state=LA|US|79|dir1=north|US|80|city1=Greenwood}} |notes= }} {{LAint|exit |location=Shreveport |lspan=13 |mile=8.370 |mile2=8.886 |exit=8 |road={{jct|state=LA|US|80}}<br/>{{jct|state=LA|LA|526|dir1=east|name1=Industrial Loop}} |notes=Location also known as [[Flournoy, Louisiana|Flournoy]];
