Interstate 70 runs for over 2200 miles from a park and ride lot east of I-695 in Baltimore, MD to Cove Fort, UT . The first interstate constructed was of I-70 in Missouri. In Breezewood, PA, there are traffic lights on I-70.

I-70 was supposed to start at I-90, but strong neighborhood opposition stopped it from intersecting there, so I-70 currently begins at a park and ride lot. It continues through Pennsylvania and St. Louis, MO. From there, it treks west through Kansas and Colorado ending at Interstate 15 near Cove Fort, UT.

US Highway 6 is the second longest US Highway behind US 20. It runs from Provincetown, MA to Bishop, CA (US 395). It starts at the very end of Cape Cod in Provincetown, then bisects Connecticut. It continues west across northern Indiana and Nebraska, then goes through Denver, CO. From Denver, US 6 takes traffic through Spanish Fork, UT and Ely, NV. It ends at US 395 in Bishop, CA.
