From Quaking Aspen across the Sierra Nevada to Olancha, Caltrans has adopted a proposed alignment, but is unlikely to build it, in part due to two protected wilderness areas — the Golden Trout Wilderness and South Sierra Wilderness — along the route. The unconstructed routing heads northeast from Quaking Aspen, cresting a small summit before following Freeman Creek easterly past the Freeman Creek Grove, crossing the Kern River near its forks, and then using the path of Rattlesnake Creek and Beach Creek to the Beach Meadows area. Crossing several ridges to the northeast, SR 190 would make its way to the South Fork Kern River near Monache Mountain, then heading southeast along that waterway to the vicinity of Haiwee Pass. That pass, elevation about 8200 feet (2500 m) above sea level, would take the highway over the Sierra Crest into Inyo County, dropping down the steep Eastern Sierra escarpment for 12.0 miles (19.3 km) in a north-northeasterly direction to US 395 at Olancha (elevation 3650 feet/1100 m).
