Work also included fiber terminations and testing to meet IADOT requirements.
Traffic signing work included removal of (6) existing overhead sign structures and installation of new systems, including (2) dynamic message signs (DMS) and multiple overhead sign trusses ranging from 66’ to 125’ spans. Additional work included installation of over (12,600 SF) of Type B guide signage, new structural foundations, and breakaway sign systems.
