The 215 Through Summerlin Is One Work Zone Until 2028. Here's Which Project Owns Which Mile.

Get on the 215 northbound near Sahara and head toward Lake Mead Boulevard, and the cones never really stop. Lanes narrow near Charleston, traffic shifts around Far Hills, and then you're climbing past Summerlin Parkway. It feels like one long project. It's actually two Clark County contracts with two crews, two budgets and two finish dates, and they meet at Far Hills Avenue.

Knowing where one ends and the other begins tells you why a backup is where it is, when it might ease, and which county page to check before you leave.

Two contracts, one seam at Far Hills

South of Far Hills, the county is widening the 215 between Charleston Boulevard and Far Hills Avenue. North of Far Hills, it's rebuilding the 215/Summerlin Parkway interchange. Here's how the two compare.

The interchange started 16 months earlier, but on paper the widening finishes first. If both stay on schedule, the 215 through Summerlin will have new pavement on one side of Far Hills for a few months while crews are still working on the other side.

Las Vegas Paving won the widening contract in March 2026. The Las Vegas Review-Journal's Road Warrior column reported a 540-day work schedule at the time. On the interchange, the fact sheet on the county's project page lists a February 10, 2025 start and a contract of about 1,100 days.

The Downtown Summerlin side gets a new way onto the freeway

The widening is the project closest to the Downtown Summerlin and Red Rock Casino area, and its biggest change has little to do with the extra lanes. It adds a braided ramp from the 215 northbound to Charleston that crosses over Hughes Park Drive East.

Rahel Shibeshi, a principal civil engineer for Clark County, explained it to the Review-Journal. The new ramps will let drivers on Summerlin Centre Drive get on the freeway directly instead of going through Charleston, and drivers coming off the 215 will get direct access to Charleston. In practice, a trip from Downtown Summerlin to the freeway won't have to fight Charleston Boulevard traffic first.

Getting there is messy. The county's October 2026 update for the widening listed grading, bridge widening, retaining walls, drainage and electrical work. The last detailed closure sheet on the project page covered October 11 to 24. It showed:

• Three lanes open northbound from Sahara to Far Hills and three open southbound from Far Hills to Charleston
• One lane open each way on Summerlin Centre Drive and on Hughes Park Drive East, with a dedicated left-turn lane at Hughes Park
• Red Rock Casino's north driveway closed and its south driveway open

That sheet has expired. Restrictions on surface streets around Hughes Park and Summerlin Centre change every two weeks or so, so check the Charleston to Far Hills project page for the current notice before you plan a drive to Red Rock or the shops on Summerlin Centre. We covered what's opened at the shopping district itself in our look at Downtown Summerlin's storefront turnover.

North of Far Hills, the week of Nov. 8

Cross Far Hills going north and you're in the interchange project. The county's weekly notice for the week of November 8 lists these 24/7 restrictions:

1. 215 northbound, Far Hills to Lake Mead: one lane and the shoulder closed.
2. 215 southbound, Lake Mead to Summerlin Parkway: one lane and the shoulder closed.
3. 215 southbound, Summerlin Parkway to Far Hills: two lanes and the shoulder closed.
4. Both directions, Far Hills to Lake Mead: temporary traffic shift.
5. Summerlin Parkway westbound, Anasazi Drive to the 215 southbound on-ramp: one lane open.
6. Summerlin Parkway westbound on-ramp to 215 southbound: one lane and the shoulder closed.
7. 215 northbound off-ramp to Summerlin Parkway: running on a temporary ramp.
8. Far Hills on-ramps: one lane and the shoulder closed in both directions. Access to 215 northbound from Far Hills is detoured.
9. 215 northbound off-ramp to Far Hills: one lane and the shoulder closed.

The southbound stretch between Summerlin Parkway and Far Hills is where the two projects press hardest on each other. Two lanes are closed there, and right after it you drive into the widening zone.

Even so, the interchange's project manager says the worst of the lane closures are behind it. Dan Erickson told the Review-Journal in late September that "this project shouldn't have any closures coming up anytime soon," because "the major portion of the work is the walls and bridge, and that is all outside of traffic." As of the end of August, about 58 percent of the work had been billed, slightly ahead of the expected pace. All but one of the five vehicle bridges were done, and the last was set to finish by the end of the year.

The backup on the hill comes from trucks

If your slowdown is southbound between Cheyenne and Lake Mead, the cones aren't the main cause. Erickson told the Review-Journal that the steady backups are on the southbound climb, where concrete trucks and other heavy trucks heading up the hill from Cheyenne toward Lake Mead "can only go up 10 mph."

That's the one stretch where the backup is set by the grade and the trucks the project needs, so it won't clear when a lane reopens. The interchange still has walls and its last bridge to build, so concrete deliveries will keep coming.

The one change coming this winter

The next change that will make the commute feel different is a single ramp. Erickson called it a major milestone when traffic starts using the new ramp from Summerlin Parkway westbound to the 215 northbound. He said the ramp will "go under that new ped bridge on the northeast corner," with timing of "maybe November or December," and that "cars will be on the ultimate alignment."

The county's November 2 to November 28 look-ahead lists active work on that ramp. If you live off Summerlin Parkway and head north on the 215 toward Lake Mead or the northwest, this is the first piece of the rebuilt interchange you'll drive on in its finished form. Until then, keep an eye on the weekly notices on the interchange project page.

The trail bridges are built, and the paths come last

Cyclists and runners get the longest wait. Three new pedestrian and bike bridges are part of the interchange project and will extend the 215 Beltway trail. The bridges are finished. The paths leading to them aren't. "That won't happen till closer to the end of the project because there's still a lot of dirt to move," Erickson told the Review-Journal.

For now, the paved trail between Far Hills Avenue and Summerlin Parkway is detoured, according to the county's notices for the weeks of November 1 and November 8. An earlier county graphic said this section would close for six months beginning "the week of March 24." The November notices still show the detour, so if your loop uses the stretch near Carriage Hill Drive, plan the detour into your route.

Here's what that adds up to. The project scheduled to finish last is the one that holds the trail connections, and the trail connections are among the last pieces of that project. Parts of the new trail bridges that cross over the interchange are likely to be among the last things on the corridor to open. If you're new to riding the west side, our guide to Red Rock's reservation rules covers the rides and hikes farther west that don't depend on the Beltway trail.

Which page to check, by where you're headed

• Downtown Summerlin, Red Rock Casino, Hughes Park Drive or Charleston: the Charleston to Far Hills widening page.
• Summerlin Parkway, Far Hills on-ramps, anything north to Lake Mead, or the trail: the 215/Summerlin Parkway interchange page, which posts weekly restriction notices and a monthly look-ahead.
• Far Hills itself: check both pages. Far Hills is where the two projects meet.

Living near a corridor that's under construction until 2028 can affect when you list a home or close on one, and how you describe the commute to buyers in the meantime. Teresa McCormick and our team follow these project pages for clients in Summerlin and can tell you how the 215 timeline fits your plans.
