Phase 3South Expressway & I80
South Expressway & I80
WB Ramps
Construction started in September 2013 with Hawkins Construction as the Prime Contractor.
- Major work included a new traffic signal intersection consisting of radar detection, mast arm ranging in size from 40′ to 65′, overhead signals and signage, Opticom pre-emption GPS equipment, NEMA 2 signal controller cabinet with battery backup system, fiber optic cabling and infrastructure modifications, and a rework of the existing 29th Ave and South Expressway intersection. Signal foundations were again constructed via drilled shafts meeting the IADOT standards for Wet Shaft construction with polymer and mineral slurries ranging in size from 36″ in diameter by 10′ deep up to 42″ in diameter by 21′ deep.
- We also installed the first adaptive traffic signal system in the City of Council Bluffs going from 32nd Ave to 23rd Ave and consisting of 5 signal intersections. Existing intersections were modified with Wavetronix Presence and Advanced detection equipment and new underground cabling. All programming for the detection equipment was completed by Sadler Electric’s in-house employees and consisted of multiple detection zones and output channels per driving lane and separate BIU Channels in order to properly communicate the vehicle density volumes with the SynchroGreen Adaptive Signal software by Trafficware.
- A signing package was completed in conjunction with this project. It consisted of (1) Overhead DMS Sign structure with IADOT’s standard spread footing and stem wall construction for the foundations, (21) steel breakaway sign post, (787 sq ft) of Type B extruded back sign panels, a 70′ signing mast arm, delineators, mile markers, and chevron guidance markers.
