It heads north on 3200 West through Lake Shore, and after a few turns near the shore of Utah Lake, and a bridge over the Spanish Fork, ends up eastbound on 4000 South.

The legislature deleted SR-228 in 1969, but the north–south piece became part of an extension of SR-77, along with a portion of 4000 South connecting the I-15/SR-77 interchange to former SR-228.
