traffic. As originally envisioned, the freeway would then join I-10 in Tucson and continue to Casa Grande. However, corridor alternatives were studied, and the draft tier 1 environmental impact statement selected a recommended corridor alternative that would split from I-19 near Sahuarita and travel around the Tucson Mountains as a Tucson bypass route, then travel parallel to I-10 until Casa Grande. The two Interstates would be within miles of each other, and a short connection to I-10 is proposed in Marana. At or near the interchange with I-8 and I-10 in Casa Grande, the freeway would split from I-10 and travel in a generally westward and then northward direction as a bypass route around the Phoenix metropolitan area. Two general corridor alternatives have been identified for this bypass section. One recommended alternative would have the highway running concurrently with I-8 west to Gila Bend, turning north to its interchange with I-10 in Buckeye or Tonopah. The second recommended alternative would have the highway run concurrently with I-8 east to an intersection with either Loop 303 or the Hassayampa Freeway, and then follow some combination of those highways, SR 30, or SR 85 to an intersection with I-10 in or near Buckeye. North of I-10 in Buckeye or Tonopah, the study has identified a general corridor roughly parallel to the Hassayampa River with two more specific corridor alignments. The first would create a new highway running north to the US 60/SR 74 intersection in Morristown before turning northwest to run concurrently with US 60 to its intersection with US 93 in Wickenburg, thereafter, running concurrently with US 93 to the northwest. The second alignment would follow the alignment of the Hassayampa Freeway as proposed by the Maricopa Association of Governments to an intersection with US 93 northwest of Wickenburg in Yavapai County. The highway would then run concurrently with US 93 through northern Arizona, including a concurrency with I-40 in and near Kingman. After leaving Kingman, the highway would continue north, crossing the Mike O'Callaghan–Pat Tillman Memorial Bridge into Nevada. Nevada In Nevada, the highway currently begins at the Arizona state line on the Hoover Dam Bypass, then runs along the Boulder City Bypass around Boulder City, which opened on August 9, 2018. It is signed concurrently with US 93 throughout. At mile 14, I-11 intersects and joins with US 95 heading north. Continuing northwest, the highway runs along a former
