Corridor 11

Originating from Gila Bend, Arizona I-11 travels north into Nevada crossing the new Colorado River Bridge near the Hoover Dam. This interstate would replace existing US-93 and I-515 south of Las Vegas. North of Las Vegas the route will generally follow US-95 northward throughout the state north through Fallon. I-11 would be cosigned with I-80 from Fallon Junction to Winnemucca before continuing north along US-95 into Oregon. Eventually the route continues north toward Boise and Lewiston eventually ending in Spokane.

From Ely the northern route follows along US-50 to Fallon and then ends in Fernley terminating at I-80. The southern route would generally follow US-6 toward Tonopah and Bishop connecting to I-11 and ending at I-9 where at some point it could be extended westward into California as a second interstate route to the California Central valley and Bay Area region.

Central Colorado

The Greater Denver metro region is growing significantly and so are other major Colorado cities such as Colorado Springs and Pueblo. Highways are becoming more congested in the region. Several "Ultimate Interstate" highway proposals in central Colorado would help make better connections to cities along the I-25 corridor and better connect the plains cities to the ports located on the Gulf Coast.
