Document Description
Southbound I-15 Ramps: The existing southbound ramps to SR-79S will be eliminated and replaced with a new far side exit loop ramp which is paired with a new southbound entrance ramp, which will intersect SR-79S opposite the existing Front Street intersection. The southbound exit will be reconfigured to provide a two lane exit with 396.24 meters (m) (1,300 feet) of auxiliary lane preceding the exit. A new bridge structure will be constructed over SR-79S to accommodate the new southbound exit ramp configuration. Northbound I-15 Ramps: The northbound exit ramp will be widened to provide four lanes at the ramp intersection. The northbound entrance ramp will be widened to provide three lanes at the ramp intersection and a three-lane ramp meter entrance to I-15. SR-79 South: Improvements include elimination of the sidewalk, curb and gutter, and parkway on the south side of SR-79S through the interchange area and paving/restriping to provide three through lanes and two left-turn lanes in each direction of travel.
