In 1988, Colorado DOT and the firm of Daniel, Mann, Johnson, & Mendenhall, Denver, the oversight consultant on the project, set out to bring the highway up-to-date and promote alternate modes of transportation. With funding from the Federal Highway Administration, the Federal Transit Administration, the Regional Transportation District, and the city and county of Denver, Colorado DOT planned to reconstruct six major interchanges, build 44 new highway structures, refurbish the existing six to eight lanes and add two new center lanes for the exclusive use of high-occupancy vehicles HOV. The center lanes were designed to operate as a reversible highway, allowing commuters to head southbound and enter downtown in the morning, then letting them travel north in the evening. Almost seven years later, the project is nearly finished, and an advanced traffic-management system (TMS) will be set up by September. Completion of the TMS will put the finishing touches on a project that faced diverse challenges in construction, urban design, traffic management and hazardous-waste mitigation.
