5 1980 s 2003 constructed by Lane/Rea 1980 s-ncdot Original Design

6 RFP Design-4 Level Stack

7 High level, long span bridges 2M CY borrow for approach fills High MSE walls Detour I-85 traffic Icing Future widening RFP Design-4 Level Stack Challenges

8 Turbine Design Proposed as an alternate design Based on a European model Similar designs in FL and UK All left turning traffic - circles counter-clockwise around intersecting roads at relatively high speed Uses simple span, low level bridges, smaller structural members 2 level lower embankments, flatter roadway profiles Future widening easier, less costly

9 Thorpe, England, UK Tampa FL I-4 and I-75 Similar designs in service
