VIDEO: Neighbors in a Nephi community are feeling a little vulnerable after a semitrailer nearly took out a couple of homes when it lost control on the freeway and rumbled down a steep embankment Wednesday. Around 6 a.m., a northbound semitrailer lost control on I-15, hit a bridge structure, and crossed the median and southbound lanes of traffic before plunging into the neighborhood. Cullen Dinkel and his family were shaken awake by the loud noise and startled by how close the truck came to their home at 834 E. 850 North.
