After passing 12th Street, it regains 2 additional lanes and begins to gradually turn back towards the south as it begins ascending Lamoille Summit. The speed limit, 35 mph at 12th Street, gradually increases to 55 mph by the time it reaches Lamoille Summit. From Lamoille Summit, it continues in a general southeasterly direction into and through the community of Spring Creek, maintaining the 55 mph speed limit and 4 lanes for most of the way.
Further southeast, it passes through a roundabout in the central portion of Spring Creek where it intersects Spring Creek Parkway and Licht Parkway. Further southeast, near Palace Parkway, it again narrows down to just 2 lanes and turns due east, though it maintains the 55 mph speed limit. Just before entering the small town of Lamoille, it intersects Lamoille Canyon Road, a National Forest Scenic Byway which heads up into Lamoille Canyon.
