The urban section will have three 12-foot lanes with curb and gutter and grading for sidewalk on the south side of the roadway from Spring Canyon Trail to Albertta Drive. The rural sections of the project will be primarily two 12-foot lanes with four foot shoulders, some short sections may require curb and gutter due to steep back slopes. Horizontal and vertical curves will meet 50 mph design speeds where feasible.
