Editing Great River Road (section)

===National and other routes===
Until the early 1980s, a single Canada-to-Gulf alignment of the Great River Road, serving all ten states, was eligible for special [[Federal-aid highway program|federal funding]]. The states posted "National Route" plates above the markers on this route and marked their own alternate routes across the river, creating two alignments between [[New Orleans, LA|New Orleans]]<!--or farther south? the route defined by Louisiana state law crosses at NO--> and [[Hastings, MN|Hastings]]-[[Point Douglas, MN|Point Douglas]].<ref>{{cite web |author= Staff |publisher= [[Mississippi River Parkway Commission]] |url= http://www.mrpcmembers.com/files/MRPC_2007_info.pdf |title= The Great River Road and the Mississippi River Parkway Commission in Missouri |year= 2007 |access-date= June 20, 2014 |archive-url= https://web.archive.org/web/20080828033148/http://www.mrpcmembers.com/files/MRPC_2007_info.pdf |archive-date= August 28, 2008 |url-status= dead }}</ref> Signs marking the National Route are now used only in Illinois and Minnesota.<ref name=Goog/><!--some older assemblies in Kentucky still have it--> The National Route followed the following segments:<ref>[[Title 23 of the United States Code|23 C.F.R.]] [https://books.google.com/books?id=5CA6AAAAIAAJ&pg=PA300 661 (April 1, 1983)], added by {{USFR|41|52449}} (Nov. 30, 1976)</ref>
