• Constructing two soil nail walls along the freeway in the eastbound direction with aesthetic treatment matching the walls on the westbound side.
• Constructing three retaining walls along the SR-4 structure, Willow Ave off-ramp, and Willow Ave on-ramp.
• Replacing damaged freeway PCC pavement slabs.
• Resurfacing existing asphalt concrete along freeway and ramps.
