Editing Interstate 69 (section)

====Opposition and controversy====
The construction of the I-69 extension beyond Indianapolis has angered environmentalists. In particular, the southern portion of the route in Indiana would run through wetlands, existing farmland, and forested areas, and cut through geologically sensitive [[karst]] topography, which environmentalists argue threatens to pollute underground water systems and harm the [[rare species]] that live there.<ref>{{cite web |url = http://www.elpc.org/transportation/interstate69/index.php |title = Indiana I-69 |publisher = ELPC |access-date = January 13, 2012 |url-status = dead |archive-url = https://web.archive.org/web/20080626034249/http://www.elpc.org/transportation/interstate69/index.php |archive-date = June 26, 2008 }}</ref><ref>{{cite news |title = The World This Week: Nafty Business: 'Super Corridor' will pave over the heart of America |last = Bisbort |first = Alan |work = The Valley Advocate |url = http://www.valleyadvocate.com/article.cfm?aid=4476 |access-date = December 3, 2007 |archive-url = https://web.archive.org/web/20071201150110/http://www.valleyadvocate.com/article.cfm?aid=4476 |archive-date = December 1, 2007 |url-status = dead }}</ref> [[Fiscal conservative]]s also oppose completion of I-69, arguing that federal legislation establishing the I-69 corridor amounts to an [[unfunded mandate]] imposed by the federal government upon the states through which the highway will travel, as the legislation requires states to pursue construction of their portions of I-69 but provides no funding mechanism to cover its estimated $25-billion cost, thereby leaving cash-strapped states to figure out how to finance its construction. Three states (Louisiana, Mississippi, and Tennessee) have publicly stated they will not build their sections of I-69 until Congress appropriates funds to complete environmental studies, design, and construction in each state.{{Citation needed|date=July 2018}}
