Phase 9
I80 Westbound Bridges in East Interchange
Construction started in February of 2016 with a triple joint venture between Hawkins Construction, Cramer and Associates, and United Contractors
- Major work included the installation of (8) 120′ and 140’ high mast tower lighting poles with 48″ diameter drilled shafts ranging in size from 30’ to 48’ deep, (3711 sq ft) of Type B extruded back sign panels, (1) 50’ overhead sign structures, (1) 90’ overhead sign structure, (2) 100’ overhead sign structure, (1) 115’ overhead sign structure, and (1) 130’ overhead sign structure, and (6000’) of electrical circuits.
- The IADOT also required the removal and relocation of an existing 70’ box truss DMS Structure and Daktronics DMS Sign. The relocation of the entire structure and digital sign was required to be completed within a 2 week window. Due to the requirement to keep lanes open on I80, a 120ton crane was used to remove the entire structure and sign in one lift. The structure and DMS where loaded onto trailers and relocated to the new site. From start to finish, the entire operation for relocating the structure/DMS board was completed in three back to back nights. High praises were again given by the IADOT Commercial vehicle enforcement, IADOT/HDR, and the Joint Venture on another smooth, thoroughly coordinated and executed installation.
