Spaghetti Bowl, Reno SBX

The Spaghetti Bowl is the colloquial name for a freeway interchange in downtown Las Vegas, Nevada. It is the system interchange between Interstate 15, Interstate 515, U.S. Route 93 and U.S. Route 95, which also includes a service interchange with Martin Luther King Boulevard.

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.”
