* For example, POITRA created and maintained the public information websites for the Southeast Corridor MIS (TREX), the North Metro Major Investment Study (MIS) and the US36 Corridor MIS beginning in 1998. The North Metro Corridor Environmental Impact Statement (EIS) is part of the Regional Transportation District's (RTD) new FasTracks Project, which is advancing several corridors to the design phase.

Arapahoe Road and I-25 Photosimulations

CDOT, Arapahoe County, Colorado

When the Colorado Department of Transportation (CDOT) and the Regional Transportation District (RTD) partnered to widen I-25 and extend light rail service in the Southeast I-25 Corridor (TREX) a few interchanges were not fully re-configured. The interchange at Araphahoe Road being in need of further study fell into this category. *

Soon after the completion of the TREX project, planning began for Arapahoe Road as the I-25/Arapahoe Road Interchange Environmental Assessment (EA). POITRA Visual was selected to provide design visualization and graphic support services for the study.

POITRA Visual also created simulations of the soundwalls and abutments for the Arapahoe Road project.

The EA upgraded and widened Arapahoe Road and replaced the existing three-span I-25 structure with a longer two span structure. The new pier and abutment configuration was necessary to correct the odd lane arrangements the existing pier locations forced on Arapahoe Road.

POITRA photographers selected a vantage point that focused on the odd lane arrangement and the corrections but could be expanded to panorama form to also give good views of the new abutments, retaining walls and proposed landscaping. This could prove useful in designing aesthetic treatments.

POITRA artists began the simulation by replacing the bridge and then laying out the new lane configuration from CADD plans.

The new elements were added and and the old elements removed using traditional digital painting techniques. Particular effort was expended creating the new background areas previously hidden by the existing bridge abutments and piers.

Portions of the large panorama include aesthetic treatments to abutments, retaining walls and landscaping. The new Arapahoe Road median too was the subject of urban landscape design. POITRA artists emulated aesthetic treatments and landscaping similar to many south I-25 interchanges to complete these areas.

CDOT and Arapahoe County used the simulations in design meetings with the special citizens Action Committee, and area residents during the EA public process. The simulations also appeared in the EA documents. end of article
