CDOT needed a quick and easily understood method to convey the proposed viaduct design to the non-technical public and agency stakeholders. An aerial photo-simulation was determined to be the most appropriate solution. The background photograph was acquired through a stock aerial photograph supplier.
The Engineer provided a surface model of I-25 as the basis for POITRA modelers to create viaduct superstructure and substructure in 3D. The model was view matched it to the photograph in order to accurately locate the alignment with new piers, walls, barriers and even laneage. The previous bridge and roadway design experience of the POITRA Visual principals made the process quick and accurate.
Traditional digital painting techniques were used to finish the simulation.The off system streets were carefully modified to reflect the new lane configuration below and leading up to the new viaduct. New walks, medians, landscaping and expanded parking areas were added.
The RTD light rail viaduct running south along I-25 was added in a very conceptual stage. The transit station at Broadway would serve as the northern terminous for another POITRA project, the Southeast Corridor light rail line, also known as TREX.
The final existing and proposed photosimulation images were used in CDOT's public process.
