As construction of Nevada’s first Diverging Diamond Interchange (DDI) at Interstate 580 and Moana Lane nears completion by Thanksgiving Day, the Nevada Department of Transportation and project partners are giving motorists an on-line sneak peek.
Beginning Monday, Nov. 19, NDOT will launch a diverging diamond Twitter countdown by sending out 10 days of Twitter updates on the Moana DDI. Each day’s tweet will feature a DDI construction alert, photo or driving tip. Those interested can receive the tweets by following @nevadadot on Twitter.
“Our Twitter feed is where drivers can go for social media road alerts, project updates and other statewide road information,” NDOT Communications Director Sean Sever explained. “We also have a Facebook page with daily updates and insights, and our 511 Travel Info system for up-to-the-minute road conditions.”
NDOT partnered with FOX 11 and Bobos Ski and Board to create an awareness and education campaign for motorists to drive the virtual DDI prior to traffic opening. The campaign encourages the public to access FOXReno.com and take the virtual tour of the DDI. Participants will be entered to win a ski package from Bobos.
Diverging Diamond Interchanges
At diverging diamond interchanges, traffic briefly crosses over to the left (opposite) side of the roadway, safely guided by traffic signals. As drivers approach the intersection, road signs and striping easily guide them to the left side of the roadway and back again to the standard side of the road. The unique interchange configuration enhances safety and traffic flow by allowing a free left turn onto freeway on-ramps. Diverging diamond interchanges in other states have decreased crashes by approximately 50 percent and reduced intersection travel time by nearly 40 percent.
Moana Lane Diverging Diamond Interchange Project
NDOT’s approximately $6.9 million Moana Lane Diverging Diamond Interchange Project, constructed by Granite Construction, utilized a fast track, two-phase construction schedule to minimize construction impacts. With the support and patience of the local residents and businesses, the project team has worked literally around the clock to open the DDI prior to Black Friday in only 70 calendar days including weekends. The project will also build landscape and aesthetic improvements and “green” bike lanes offering safer bicycling and pedestrian access within designated, color-coded bike lanes. This project is the first transportation project in northern Nevada to use the Construction Manager at Risk (CMAR) construction method to more collaboratively, quickly and efficiently complete the project.
