It runs south from I-10, intersects with [[U.S. Route 90 in Louisiana|U.S. Route 90]], and ends at the Almonaster Boulevard [[interchange (road)|interchange]], near the [[NASA]] [[Michoud Assembly Facility]]. From this point, the highway continues south over the [[Gulf Intracoastal Waterway]] / [[Mississippi River Gulf Outlet]] on the [[Green Bridge (New Orleans)|Green Bridge]]. The Interstate spur route is a portion of Paris Road, a [[New Orleans metropolitan area]] roadway stretching from the [[Mississippi River]] to [[Lake Pontchartrain]] dating back to the 19th century. The portion designated I-510 is entirely within the [[Ninth Ward of New Orleans]], though the area the highway runs through is locally known as [[Eastern New Orleans|New Orleans East]]. ==Route description== [[File:Interstate 510 northern terminus from Interstate 10 eastbound.jpg|thumb|left|Northern terminus from I-10 eastbound.]] I-510 [[concurrent (road)|runs concurrently]] with [[Louisiana Highway 47|Louisiana Highway 47]] (LA 47) for its entire routing. The spur serves the NASA facility, the [[St. Bernard Parish]] seat of [[Chalmette, Louisiana|Chalmette]] (though the interstate portion ends a few miles north of the city, the highway continues as Paris Road), and the former [[Six Flags New Orleans]]. I-510 exits are numbered from the parent route to the remote terminus, as is normal for spur interstates.<ref>{{cite web |title = Manual on Uniform Traffic Control Devices, 2009 Edition |url = https://mutcd.fhwa.dot.gov/htm/2009/part2/part2e.htm |publisher = FHWA |access-date = 1 April 2011 }}</ref> ==History== What would eventually become I-510 was originally proposed in 1970 as a replacement for Paris Road, but was subsequently delayed due to environmental concerns.<ref name="October 13, 1992">{{cite news |first = Karen |last = Turni |title = I-510 link is nearly complete after 7 years of construction |publisher = New Orleans Times-Picayune |page = A1 |date = October 13, 1992 }}</ref> By 1981, an environmental impact statement was completed, and construction on the spur would commence in 1985.<ref name="October 13, 1992"/> The $87 million project saw its official ribbon-cutting on November 13, 1992.<ref name="November 14, 1992"/> I-510 was once planned as part of a longer [[Interstate 410 (Louisiana 1969)|I-410]] that would have also incorporated [[Interstate 310 (Louisiana)|I-310]] around the southern section of the [[New Orleans metropolitan area]].<ref>{{cite web |first= Richard F. |last= Weingroff |date= November 18, 2015 |url= https://www.fhwa.dot.gov/infrastructure/neworleans.cfm |title=The Battles of New Orleans: Vieux Carré Riverfront Expressway (I-310) |work= Highway History |publisher= Federal Highway Administration |access-date= February 9, 2016}}</ref> ==Exit list== {{Unreferenced section|date=November 2023}} {{LAinttop|exit|Parish|parish=Orleans|location=New Orleans}} {{LAint|exit |type=concur |mile=3.04 |exit=- |road={{jct|state=LA|LA|47|dir1=south}} |notes=Southern terminus }} {{LAint|exit |mile=2.91 |exit=2C |road=Almonaster Boulevard, {{scaps|To}} Old Gentilly Road }} {{LAint|exit |mile=2.28 |exit=2A |road={{jct|state=LA|US|90|name1=[[Chef Menteur Highway]]}} |notes=Signed as exits 2B (east) and 2A (west) northbound }} {{LAint|exit |mile=1.15 |exit=1B |road=Lake Forest Boulevard }} {{LAint|exit |mile=0.00 |mspan=2 |exit=1A |road={{jct|state=LA|I|10|city1=New Orleans|city2=Slidell}} |notes=Southbound exit to I-10 west unsigned; I-10 exit 246A }} {{LAint|exit |mile=none |type=concur |exit=- |road={{jct|state=LA|LA|47|dir1=north|city1=Little Woods}} |notes=Northern terminus; northbound exit and southbound entrance; I-10 exit 246B }} {{Jctbtm|keys=concur}} ==References== {{Reflist}} ==External links== {{AttachedKML|display=title,inline}} {{3di|10}} {{NOLA Streets}} {{DEFAULTSORT:I510}} [[Category:Auxiliary Interstate Highways|10-5]] [[Category:Interstate 10|510]] [[Category:Interstate Highways in Louisiana|10-5]] [[Category:Transportation in New Orleans]]
