The Las Vegas Beltway carries two numerical designations. Approximately {{convert|11.1|mi|km}} of the highway, from its southern terminus at Interstate 11/Interstate 515/U.S. Route 93/U.S. Route 95 in Henderson west and northwest to Interstate 15, is signed as Interstate 215 (I-215); however, only two distinct portions of this section (I-515 to Stephanie Street and Warm Springs Road to I-15), totaling a little over {{convert|4.6|mi|km}}, are maintained by the Nevada Department of Transportation.[1] Clark County Route 215 (CC 215) composes the remaining {{convert|39.2|mi|km}} of this semi-circumferral highway, with the county's Department of Public Works responsible for all construction and maintenance (the county also maintains the {{convert|6.7|mi|km|sing=on}} middle section of the aforementioned southeast leg signed as I-215). The Las Vegas Beltway currently consists of two different road types: freeway and an interim expressway. The beltway is currently a freeway from the I-515 interchange in Henderson to just west of US 95 in northwestern Las Vegas. The remainder of the beltway is a mix of freeway and expressway, with several of the expressway sections being upgraded to Interstate freeway standards. The beltway was planned and constructed by Clark County. This marked the first time in the United States that a county has overseen the construction of an Interstate highway with little to no state or federal funding. Once completely upgraded to freeway, it is anticipated that the CC 215 portion of the beltway will be designated I-215 and the entire facility turned over to the Nevada Department of Transportation for maintenance. Route descriptionThe Las Vegas Beltway begins in Henderson, at the I-11/I-515/US 93/US 95 interchange, where traffic on westbound State Route 564 (Lake Mead Parkway) defaults onto I-215 west. From here, the beltway primarily follows the former Lake Mead Drive alignment west to the Pecos Road/Saint Rose Parkway (SR 146) interchange. The highway then curves northwest towards McCarran International Airport before turning west to cross under Las Vegas Boulevard and I-15. As the beltway passes under I-15, it changes from Interstate to county highway still maintaining freeway status as it heads nearly due west. Passing Decatur Boulevard, two one-way frontage roads (which formerly carried the initial beltway facilities) appear on either side of the highway. At Durango Drive, the roadway curves northward. The frontage roads end as the highway reaches Tropicana Avenue, but the freeway continues briefly west and then north again to intersect Charleston Boulevard (SR 159) near Red Rock Canyon. As it passes north through the community of Summerlin (part of the city of Las Vegas), it meets the Summerlin Parkway freeway at a recently upgraded system interchange. The beltway downgrades from freeway to an expressway (with some grade separations) after it passes the Cheyenne Avenue/Cliff Shadows Parkway interchange. From here, the road continues north along the western foothills of Las Vegas to pass behind Lone Mountain. Soon afterward, the highway curves east and intersects US 95 at a yet to be upgraded partial interchange. From there the beltway continues nearly due east along the alignment of Centennial Parkway before entering northern North Las Vegas at Decatur Boulevard. From there it swings northeast, passing by the large Aliante development before turning east again. Much of the final few miles of the route from here on are in undeveloped land, except near the interchange at 5th Street, with intersections existing primarily as turnarounds, until the beltway swings southeast just past Lamb Boulevard and reaches its ending terminus at I-15 just west of the Las Vegas Motor Speedway. HistoryAASHTO approved the I-215 designation for approximately {{convert|18.9|mi|km}} of (then unbuilt) highway, from Tropicana Avenue to US 95 (I-515) on April 17, 1993.[2] As eventually built, this specific portion of the beltway is {{convert|19.59|mi|km}} in length. Much of the beltway was built completely with local funds, and expressway to freeway upgrades have continued to be built without state or federal money (except for the I-515 interchange upgrade). A tax measure voted on by the County residents increased funding for the beltway. As a result, it was expected to be fully upgraded to a freeway by 2013, rather than the previous goal of 2025.{{Citation needed|date=February 2012}} However, at present it appears that this target date will slip back at least a few years. The first section of I-215 opened to traffic in 1996 from I-15 to Warm Springs Road, including the Airport Connector and tunnel, which linked McCarran International Airport to southern metro Las Vegas without requiring motorists to use Tropicana Avenue or Russell Road to access the main passenger terminal. The southeast leg of the beltway (except for the I-515 connection) was completed ahead of schedule in 1999, while the northern end was extended from Decatur Boulevard in 1998 to Tropicana Avenue by 2000. The remaining sections in the western and northern legs of the beltway were completed by 2003 – either in their final, full freeway mode or in one of two lesser interim configurations. I-215 was built on the State Route 146 alignment between a point just east of Exit 6 (Saint Rose Parkway/Pecos Road) and Mile 0 (the Interstate 515/U.S. Route 93/U.S. Route 95 interchange at Lake Mead Parkway, formerly known as Lake Mead Drive). Since the Nevada Department of Transportation (NDOT) does not co-sign state routes along Interstate highways, SR 146 was truncated to its current eastern terminus at I-215. SR 146 was co-signed with I-215 from Pecos Road to I-515/US 93/US 95, even though the state highway designation no longer existed in this section when the freeway was completed. Some SR 146 signs were still remaining on I-215 as late as July 27, 2008. In 2003, the entire {{convert|50.5|mi|km|sing=on}} long beltway was opened, albeit with three different road types – freeway, limited access expressway, and as interim frontage roads – with all the newly opened sections being designated as County Route 215. On August 9, 2006 a section of freeway was completed that allowed the connection of two previously built freeway portions. This meant a continuous stretch of road consisting of about half the road's overall mileage, from the I-515/SR 564 terminus to Charleston Boulevard, was now completed to freeway standards. Roads & Bridges magazine, a national publication that provides technology news and information to the transportation construction industry, named the Las Vegas Beltway as one of the nation's Top Ten Road Projects in 2002. At the Board of County Commission meeting on March 2, 2004, the beltway was renamed as the Bruce Woodbury Beltway.[3] The Board approved a resolution recognizing Commissioner Woodbury for his many years and efforts in the future of transportation in the valley. Recent and future improvementsConstruction of the North 5th Street Interchange was completed and fully opened to traffic in September 2011. The project's scope included roadway, bridge, drainage and utility improvements along the northern beltway at the intersection of North 5th Street in North Las Vegas.[4] Beginning in 2012 and completed in 2014, construction by the Clark County Department of Public Works built-out of another northern beltway segment between Tenaya Way and Decatur Boulevard. The project widened CC 215 to four-lanes, built two new highway interchanges at Jones and Decatur Boulevards, and a new bridge to carry Bradley Road over the freeway. Improvements to the beltway were also completed in the southern region of the valley with upgrades between I-15 and Windmill Lane. This project provided one additional travel lane in each direction, auxiliary lanes between interchanges and included the widening of four bridges over I-215 at Paradise, Warm Springs, and Robindale roads as well as for the Airport Connector.[5] Additionally, The beltway from Decatur Blvd to North 5th Street was built out between 2014 and Fall of 2016. A new bridge was built for the expected extension of Revere Street and the roadway widened to a four-lane freeway from Decatur Boulevard to North 5th Street. Current construction projects on the 215 Beltway include a conversion of the roadways between Craig and Hualapai to a four-lane freeway with interchanges at Lone Mountain Road and Ann Road and a grade separation for Centennial Parkway[6] , and the further improvements to the Airport Connector with the Airport Connector 2 project. Additionally, phased construction of the Centennial Bowl system interchange between the Beltway and the US 95 freeway in the northwest valley continues. The NB 95 to EB 215 ramp was completed on May 28, 2016. The WB 215 to SB 95 Flyover ramp opened on July 12, 2017. Additionally, an expanded bridge over Montecito Parkway is also under construction in anticipation of the widening of the Beltway between Durango Drive and Tenaya Way as part of construction of the Centennial Bowl.[5] Exit list{{jcttop|exit|state=NV|county=Clark}}{{NVint|exit|location=Henderson |lspan=7 |type=trans |mile=0.00 |mspan=2 |exit=— |road={{jct|state=NV|SR|564|dir1=east|name1=Lake Mead Parkway}} |notes=Continuation beyond eastern terminus of I-215 }}{{NVint|exit |mile=none |exit=1 |road={{jct|state=NV|I|11|dir1=south|I|515|dir2=north|US|93|US|95|city1=Boulder City|city2=Las Vegas}} |notes=I-11 northbound exit 22;
