Route description

State Highway 48 starts at a diamond interchange with I-15 before heading due east on North Berrett Road through the town Roberts, where it becomes the road East 627 North. SH 48 continues north on Old Highway 91 before turning east and leaving the city of Roberts as Roberts Highway (also known as East 650 North), crossing Roberts Slough. Near the town of Lewisville, SH 48 turns south onto Saint Leon Road (alternatively known as North 3500 East), passing Midway Elementary School and Jefferson Alternative High School as it enters the town of Lewisville.
