The $130 million overhaul of the 215 Beltway/Summerlin Parkway interchange in Las Vegas has quietly crossed the halfway point, with crews finishing four of five new vehicular bridges and a key northbound ramp expected to open to traffic by the end of the year. Project manager Dan Erickson says the massive rebuild, which broke ground in February 2025, is now roughly 58 percent billed as of the end of August.
According to the Las Vegas Review-Journal, the final of five new vehicular bridges is expected to be finished by the end of 2026, and the new Summerlin Parkway westbound ramp to 215 northbound should begin carrying vehicles around November or December. That ramp passes beneath the completed pedestrian bridge at the northeast corner of the interchange, part of a broader package of walkways. Erickson told the paper that the bulk of remaining work involves walls and bridges built outside the flow of traffic.
A Three-Year Rebuild Taking Shape
Clark County Public Works detailed the scope of the project in June 2025, describing a three-year undertaking that includes eight bridge structures, roadway improvements, ramp reconfiguration, new ramps, retaining walls, drainage facilities, sidewalks and utility modifications, according to swcpa.org. That total breaks down into five new vehicular bridges and three new pedestrian trail bridges, per the Review-Journal's reporting, along with several retaining walls scattered throughout the project footprint.
Construction on the interchange began on February 10, 2025, according to 963kklz.com, which reported the work includes widening the Beltway, reconfiguring ramps and constructing new bridges. The station described the project as aimed at greatly improving traffic flow and safety through a stretch of roadway that serves both daily commuters and recreational traffic heading toward the western valley.
One Signal Instead Of Several
The redesign's biggest structural change is a new flyover ramp carrying 215 southbound traffic directly onto Summerlin Parkway eastbound. Per the same swcpa.org report, the goal is a continuous freeway connection between the two roadways that reduces the interchange down to just one traffic signal, replacing what has been a tangle of multiple signals. That matters given the intersection's traffic load — more than 17,000 vehicles a day at peak usage, according to the same source.
Pedestrian and bicycle bridge paths won't be ready as soon as the vehicle lanes, however. The Review-Journal's report notes those walkways are being delayed by remaining dirt-moving and related project work, and are expected to come online closer to the end of the overall project rather than alongside the new ramps.
What Drivers Can Expect Through Late October
Scheduled work between Monday and October 23 will touch nearly every leg of the interchange, spanning 215 in both directions between Far Hills Avenue and Lake Mead Boulevard, the 215 northbound off-ramps to Far Hills and Summerlin Parkway, the Far Hills ramps to Summerlin Parkway and to 215 in both directions, and the Summerlin Parkway westbound on-ramp to 215 southbound. Crews are also working on Summerlin Parkway westbound between Anasazi Drive and the 215 southbound on-ramp, plus the new westbound on-ramp to 215 northbound.
Despite that long list, the outlet reports the upcoming work will not require major lane closures. Erickson said motorists should still slow down through construction zones, and the article notes that 215 southbound traffic already sees periodic backups when concrete trucks or other heavy vehicles climb the hill from Cheyenne toward Lake Mead at speeds as slow as 10 mph.
Timeline Discrepancy On When It All Wraps
Exactly when the project will be finished depends on which account you read. The Review-Journal reports the interchange rebuild is scheduled for completion in spring 2028, while swcpa.org's June 2025 report put targeted completion at February 2028. Motorists are being reminded, per the Review-Journal, to obey posted speed limits and use extra caution in the work zone as the project continues after passing the halfway point.
