NDOT Spaghetti Bowl Xpress (SBX)

From NDOT: “Known as Spaghetti Bowl Xpress, the first phase of spaghetti bowl renovations will restripe eastbound Interstate 80 lanes between Wells Avenue and the Spaghetti Bowl and widen the eastbound I-80 to southbound I-580 Spaghetti Bowl ramp to two lanes. Auxiliary merge lanes and improved ramps will also be added on southbound I-580 between the Spaghetti Bowl and Plumb Lane, along with sound and aesthetic walls. Sections of pavement on northbound I-580 will also be repaired. The first phase of construction will not require relocation of any residences or businesses.

Additional interstate improvements will be built in prioritized phases through 2039 as funding is identified. Approximately 250,000 vehicles per day currently travel through the spaghetti bowl. The Reno-Sparks population is expected to increase 27 percent by 2040. Without the future improvements, population growth is anticipated to lead to travel delay increases of 53 percent through the Spaghetti Bowl.”

AQD (Ames Q&D Constructors) is the design-builder.  Q&D is a joint venture partner on the SBX project with Ames Construction. Horrocks Engineers is the designer.
