I-5 and Hammer Lane Interchange Photosimulations

CalTrans and City of Stockton, Stockton, California

POITRA Visual provided photo-realistic simulations for the I-5 North Stockton Corridor, which studied the I-5 Corridor through Stockton, California to make capacity improvements. The project resulted in highway widenings throughout the I-5 corridor, several interchange redesigns, and two new interchanges.

The interchange redesigns included the I-5 and Hammer Lane Interchange. The redesign featured additional ramp storage lanes and improved access from Hamer Lane. Photo-simulation was the medium chosen as the best way to accurately communicate the proposed design to project team members and to the public.

The simulation needed to show the variations under consideration for the interior lanes and median of I-5. The alternates were a mixed flow interior lane versus a High Occupancy Vehicle (HOV) lane and an open median with w-rail versus a paved median with concrete barrier.

POITRA artists plotted the lane configurations, medians and property takes onto the Engineer provided photograph from design plans. Using traditional digital painting techniques POITRA adjusted the interchange ramps, soundwalls, proposed laneage, lighting, sidewalks, medians, and landscaping. The previous bridge and roadway design experience of the POITRA Visual principals always plays a key role in accurately interpreting and representing the Engineer's design.

The final aerial simulation images were used as meeting materials for the City of Stockton's public involvement process.end of article
