Conservation groups say the proposed Arizona routes for an Interstate 11 project failed to consider habitat for imperiled desert species.

The proposed freeway would run from Wickenburg to Nogales and has been subject to lawsuit filed by a conservation group.

As Arizona’s Family reported, one of the threatened species is the cactus ferruginous pygmy owl, whose climate would be threatened as part of the highway’s construction.

In response to a lawsuit from conservation groups, the Federal Highway Administration and Arizona Department of Transportation have agreed to halt planning activities and reevaluate their approval of Interstate 11.
