RDV Helps Arizona DOT with Public Involvement for Highway SR303L

Location: Goodyear, AZ | SR-303 Loop from I-10 to SR-30.
Arizona’s State Route Loop 303, or SR303L, is a freeway that currently encircles the Northwest quadrant of the greater Phoenix area, running 35 miles from highway I–17 to the North of Phoenix to highway I–10 to the West. In late 2018 the Arizona Department of Transportation and engineering consultant WSP completed the environmental assessment and final design concept report for extending SR303L four miles South from its current terminus at Van Buren Street in the City of Goodyear to connect with the planned SR30 freeway.
The proposed design calls for a controlled–access urban freeway with four general use lanes and one HOV lane in each direction. It overlays the existing four–lane arterial Cotton Lane for approximately two miles, providing auxiliary lanes, one–way frontage roads, and grade–separated interchanges. It also includes a freeway–to–freeway flyover interchange with the planned SR30 highway. Construction is planned to begin in 2020.

Before finalizing the EA and final design, WSP and ADOT conducted meetings to present the proposed project to the public, local agencies, and other stakeholders. To facilitate communication they turned to RDV Systems, Inc. to provide a 3–D visualization model showing both the existing and proposed conditions.
“RDV had worked on other ADOT projects and had shown they could deliver a quality product quickly and at a reasonable cost, so they seemed the natural choice to help us with our visualization needs.”
Tom O'Reilly, Project Manager 
RDV began developing the model in early May 2018, delivering the final product in time for ADOT’s public hearing on June 27. In addition to the proposed design elements, RDV also had to model the highly complex existing interchange between SR303L and highway I–10.
RDV also conducted training for the project team to show them how to use its 123BIM applications for interactively viewing the model and creating images, videos, and other visualization assets.
“We take a different approach to visualization. Instead of delivering images and videos we create an interactive 3–D project model. That lets the people directly involved in the project decide for themselves what they need to show, and gives them the tools to create these assets quickly and easily.”
Natan Elsberg, CEO and founder

“The Public Hearing was a huge success and we couldn’t have done it without RDV’s work. The public was very receptive to the video simulations and it was a very positive tool to show property owners what the proposed freeway might look like.”
Tricia Brown, Project Manager 
WSP and ADOT used the 123BIM tools to create still images, flyover videos, and drive–through videos showing both existing and proposed conditions which were used in their outreach events. They also set up a 123BIM Virtual Tour, giving the public a way to interactively explore the project on their own.
