Environmental groups are going to court to stop further development of the proposed 280-mile Interstate 11 project from Nogales to Wickenburg, saying federal officials have not complied with legal requirements.
The lawsuit charges that the Federal Highway Administration, in approving one alternative route around the west side of Tucson, failed to consider the destruction to the Sonoran Desert, harm to wildlife and effects on air pollution. Those effects would be less if the highway is co-located with Interstates 19 and 10, it says.
