SE3, as a subconsultant, assisted in the preparation of final design plans (Phase II Engineering) for the realignment of US-30 from just southeast of IL Route 59 to the I-55 Ramp in Plainfield, IL. SE3 was responsible for the preparation of temporary and modernized traffic signals at Frontage Road and at I-55 Southbound Ramp (temporary).
Temporary traffic signal plans were needed to accommodate multiple phases of roadway construction. A traffic signal interconnect for both the temporary and permanent conditions was provided. The final interconnect now runs from the I-55 southbound ramp intersection to Renwick Road.
In addition to the traffic signal design, SE3 prepared the hydraulic analysis and design for the proposed storm sewers from I-55 to Lily Cache Road.
The overall project included the reconstruction and widening of US-30, multi-use path improvements, drainage, and structure rehabilitation over Lily Cache.
