WisDOT I-39/CTH B Interchange

Plover, Wisconsin

SRF completed the configuration analysis, environmental documentation, FHWA approval documentation, and preliminary design for the CTH B interchange with I-39 in Plover. The project included two ramp terminal intersections and two adjacent arterial road intersections and a complex Interchange Control Evaluation that investigated five interchange configurations. SRF completed the ICE process and secured WisDOT Central Office approval of a diverging diamond interchange (DDI) alternative configuration. SRF then completed the NEPA process (Environmental Report) through Region review and the Interstate Access Justification Report for FHWA approval.
