Consultant Engineering, Inc. (CEI) was selected to provide construction administration and inspection for four projects along Hunt Highway, which include:
- Hunt Highway Phase 4 – a 2.5-mile segment that runs from Bella Vista Road to Magma Road

- Hunt-Magma Phase II and III Flood Mitigation – new drainage channels along and near Magma Road to convey storm runoff under Hunt Highway to large detention basins along the Copper Basin Community.
Prior to construction, CEI worked closely with the designer and utility companies for constructability reviews and relocation schedules.
