Jorgensen has prepared 13 Road Design Manuals for State DOTs and the Emirate of Abu Dhabi; see the table below. Based on the quality of our work, Jorgensen has been retained by the DOTs in Maine, Connecticut, Mississippi (twice), Montana (twice), Oklahoma, South Carolina, and Illinois (twice) to update the Road Design Manuals after Jorgensen’s original work. Each of these manuals is a comprehensive, user-oriented document tailored to meet the prevailing conditions within the State. The manuals address context sensitive solutions, functional classification, design speed, design vehicles, sight distance, horizontal and vertical alignment, cross section elements, intersections, interchanges, roadside safety, etc. In addition, the Road Design Manuals have addressed project development, plan preparation, quantity estimates, cost estimates, design exceptions, specifications, reports, etc. For background and source material, Jorgensen uses the AASHTO A Policy on Geometric Design of Highways and Streets, AASHTO Roadside Design Guide and several other national documents published by AASHTO, Institute of Transportation Engineers, Transportation Research Board, and other organizations.
