Interstate 70 Extension - Nevada
Description From its existing terminus in Utah, this interstate would generally follow existing US-50/6 route to Ely. From there the interstate would continue west along one of two possible routes. 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.
Purpose and Need To promote interstate continuity and provide a link to the current west end of I-70 for several major cities such as Reno, Sacramento and the Bay Area.
Preferred Routing Since the likelihood of traversing the central Sierra Nevada mountains is low due to the high elevations and associated construction costs the southern route is likely impractical. Favoring the northern route is preferred even though the route travels through largely desolate areas on its way westward. Despite this the additional connection to existing I-70 to points west makes this highway justifiable
Interstate 501 - California/Oregon
Description This interstate would replace existing US-199 from Crescent City to Grants Pass.
Purpose and Need Continuity with the existing interstate system. and a logical connection to I-5
