The early alternatives that the EIS looked at included two alignments that re-routed I-70 with a long out of direction loop to the north. A visual simulation was required to show the proposed structure which would displace the National Western Stock Show Complex on the more western of the two alignments. The Stock Show is a major Denver attraction.
POITRA modelers created an accurate 3D model of the viaduct and ramps which was camera matched with the base photograph. Artists cound then determine what areas of the background would need to be restored.
We have a background in actual highway and bridge structure design so detailed plans and projects are no problem for POITRA.”

Several stock show buildings were to be removed from the path of the new viaduct. In the simulation view these removals would exposed views of the mountains beyond. POITRA artists carefully reproduced the view as they removed the appropriate foreground buildings. New curb, gutter and walks were included in the alternative where the project changed traffic patterns of local streets. This was accomplished in the simulation using traditional digital painting techniques. The 3D model was then lighted to match the photograph, rendered and composited with the base photograph to create the final simulation.
The complex arrangment of ramp alignments and profiles required special effort. POITRA was able to call on its principal's previous career experience in bridge design to ensure accuracy and efficiency.
The finished simulations were used by CDOT in the I-70 East EIS public meetings, newsletters and as exhibits in the Draft EIS Document.
