HR Green Selected to Conduct I-90 Exit 406 Interchange Modification Study and Environmental Assessment
HR Green was chosen by the South Dakota Department of Transportation to perform an Interchange Modification Justification Report (IMJR) and associated environmental investigation for the I-90 Exit 406 interchange.
The challenges to transportation project designers are more difficult today than ever. Right-of-way (ROW), easements, utility adjustments, and the ability to efficiently stage construction while safely maintaining traffic are critical factors to keep projects on track, especially in constrained urban settings. Add to the mix are a broad range of regulatory clearances that must be obtained in a sequential manner during the National Environmental Policy Act (NEPA) process to keep the project on schedule. These clearances are often based on conceptual and preliminary design that if not thoroughly developed during the location and route studies phase can lead to rework and schedule delays later in the project life cycle.
The I-29 reconstruction project will improve safety, traffic operations and infrastructure conditions, and provide for enhanced driver expectancy.
HR Green, Inc. led the consultant team that prepared Interchange and Corridor Location Study documentation, including supporting technical reports for goals and objectives, multimodal needs, travel demand forecasts, preliminary environmental screening analysis, and an alternatives analysis.
