Construction will begin on Nevada’s first Diverging Diamond Interchange (DDI) at I-580 and Moana Lane on Wednesday, September 12, 2012. This is also the first transportation project in northern Nevada to use the Construction Manager at Risk (CMAR) method of procurement and install “green” bike lanes. The project is on a fast-track construction schedule and includes two phases.
Phase one includes reconstructing the I-580 southbound Moana Lane off-ramp and prep work to reconstruct the northbound on and off-ramps. The I-580 southbound Moana Lane off-ramp will be closed 24-hours-a-day, seven-days-a-week beginning Wednesday, September 12, 2012 for an estimated four weeks. Motorists are encouraged to use Plumb Lane or Virginia Street/Kietzke Lane exits.
Phase two includes reconstruction of the I-580 Moana Lane northbound on and off ramps and the southbound on ramp, and Moana Lane from just west of the southbound off-ramp to just east of the northbound off-ramp. During phase two the following closures will be in place 24-hours-a-day, seven-days-a-week for an estimated five weeks:
- I-580 northbound on and off ramps
- I-580 southbound on-ramp
- Moana Lane underneath I-580 from just west of the southbound off-ramp to just east of the northbound off-ramp
Diverging diamond interchanges are often used at intersections located beneath or above freeway bridges. Traffic briefly crosses over to the left (opposite) side of the roadway, safely guided by traffic signals, physical barriers, and pavement markings at each crossover. Vehicles turn left onto freeway on-ramps without stopping and without conflicting with through traffic. Green bike lanes provide a clearly defined and dedicated lane for bicyclists by painting a green box in the lane.
To drive the virtual Moana Lane DDI access Moana395.com. Driving the Moana Lane DDI is safe and easy. As you approach the intersection, road signs and striping easily guide you to the opposite (left) side of the roadway and back again to the standard (right) side of the road. If you are accessing the freeway, you will follow signs to make an easy left-hand turn onto the freeway entrance.
