The North Central Expressway (US-75) project in Dallas, Texas, is a total urban freeway reconstruction that provides an excellent case study for the new range of opportunities available to transportation engineers under the new 1991 Intermodal Surface Transportation Efficiency Act. This 10-mi-long, $640 million job was planned from the outset as an innovative project that will expand the envelope of urban freeway design and be a precursor of 21st century ideas. This project encompasses many of the enhancement elements listed in the act (e.g., pedestrian and bicycle facilities, landscaping and other scenic beautification, preservation of rail corridors for bicycle trails, archaeological planning and research). The expressway offers a case study of a new environmentally sensitive "enhancement-inclusive" design approach, methods used to solicit public input into the final design, the end product of this new approach, and advice for others embarking on similar undertakings based on the experiences on this project. |
