Ask two Mayfair neighbors what their summer looks like and you may get two different answers depending on which side of Colorado Boulevard they live on. That is not a metaphor. It is a construction schedule.
The Colfax BRT project is on a segmented timeline that happens to sever Mayfair's northern border into a west half nearing completion and an east half still years from finished. The rest of the neighborhood — the 9+CO retail row, Mayfair Park, the Mayfair Neighbors calendar — is running exactly as it has for years. If you learn to read the neighborhood along those three clocks, the summer becomes legible.
The Colfax line splits Mayfair at Colorado Boulevard
Mayfair's northern border is East Colfax, from Eudora to Monaco. The Regional Transportation District's May 2026 update puts Segments 1 and 2, Broadway to Colorado Boulevard, on track for completion in fall 2026, with final paving, striping, and finishing work expected in spring 2026. That covers the first half-block of Mayfair's Colfax frontage, essentially the corner at Eudora.
East of Colorado Boulevard is a different story. Segments 3 and 4, between Colorado Boulevard and Yosemite Street, are progressing toward a fall 2027 completion, with construction underway on both eastbound and westbound stations, traffic currently flowing in outer lanes, and work shifting to center lanes as crews complete drainage, utilities, signals, and streetscape improvements through 2027. Nearly every Colfax block that Mayfair actually touches sits inside that stretch.
| Mayfair Colfax frontage | BRT segment | Status this summer | Finish |
|---|---|---|---|
| Eudora to Colorado Blvd (west edge only) | 1–2 | Finishing work in progress | Fall 2026 |
| Colorado Blvd to Monaco (the long stretch) | 3–4 | Active center-lane construction | Fall 2027 |
The practical effect is that a Mayfair resident living west of Colorado Boulevard will watch the fencing come down this year. A resident living east of it, closer to Krameria or Leyden, will spend the summer with lane shifts, staggered platform builds, and the arch structures being lifted into place block by block. Around Hudson Street, preparation for the future BRT station is underway, including underground utilities and drainage in the center of Colfax for three to four weeks, with most work on the east side of Hudson and side streets remaining open. That is Mayfair's block.
For homeowners, the split matters in a way that median-price commentary usually misses: the same neighborhood is experiencing the tail end of a disruption cycle and the front end of one at the same time, on the same street, one block apart.
What is actually opening on the strip
Openings on Mayfair's Colfax frontage have slowed since 2024, which is what BRT construction tends to do to a corridor. The one substantial addition this summer sits at 5454 E. Colfax. Owner Larry Washington brings three decades of Louisiana and Southern-style barbecue to the address, featuring fried catfish alongside smoked ribs and brisket, with live music and a full bar planned, and Catfish King is aiming for a soft opening this fall.
That is one signed lease inside a construction zone, which is telling in both directions. It says an operator with a long track record is willing to take a bet on the Colfax that emerges after BRT, and it says the corridor is quiet enough right now that the rest of the leasing pipeline is waiting. The Colfax Mayfair Business Improvement District's grant tracking shows the same picture, with small businesses on East Colfax from Broadway to Glencoe Street eligible for one-time grants of $7,500 or $15,000 based on annual gross revenue tier, intended to support businesses impacted by city-funded construction. Grant programs and slow leasing tend to travel together.
The context is not academic. As of the Denverite check-in in early May, business owners began raising alarms soon after construction started in October 2024, with many saying the maze of construction deterred customers and led to record-low sales. The neighbors most affected by this are the residents on 14th and 13th who used to walk to Colfax two or three times a week for a coffee or a haircut and now drive to 9+CO instead. Which brings us to the western edge.
9+CO is the reason the summer feels normal
If the north edge is unusual, the west edge is aggressively stable. The 9+CO redevelopment at 9th and Colorado has been open long enough that residents treat it as neighborhood infrastructure, not new development. The former University of Colorado Health Sciences Center site is surrounded by Denver's premier pre-war neighborhoods, and Park Hill, Montclair, Hale, Hilltop, Congress Park, and Country Club all sit within a short walk, along with City Park and Cheesman Park. Mayfair is the neighborhood that gets the site's front door.
The retail row is a mature mix. Postino WineCafe, Hopdoddy Burger Bar, Culinary Dropout, Blanco Tacos & Tequila, Pizzeria Locale, Gelato Boy, Clean Juice, Frank & Roze Coffee, the AMC 10-screen theater, Elevation Cycles, and Fluff Salon are all in place, along with a CVS, a Chase branch, and a Bellco Credit Union. There have been no summer 2026 openings inside the project of the scale that Cherry Creek North is seeing at the Clayton Hotel or 2nd & Adams. The absence is the story. During a summer when the Colfax corridor is running at half capacity, 9+CO is functioning as Mayfair's default walkable retail center, and it happens to be doing so without any operational changes that would require a resident to relearn it.
The one variable worth naming for buyers watching the block: the site spans roughly 26 acres, totals about two million square feet with approximately 1,100 housing units and around 150,000 square feet of office, and additional residential phases continue to lease. Milo and Theo are the two named apartment communities on the ground; the for-sale opportunities remain concentrated across Colorado Boulevard, in the Mayfair single-family fabric itself.
The calendar residents already know
Everything that programs Mayfair's interior summer comes from one nonprofit, and it has not changed. Mayfair Neighbors Inc. was formed in 1977 with a mission to advance the common interests of the neighborhood, and its borders run clockwise from the north as Colfax Avenue, Monaco Street Parkway, 6th Avenue Parkway, and Eudora Street, encompassing over 3,200 households. The recurring summer events are what long-time residents plan around:
- The Fourth of July bike parade
- The annual concert in Mayfair Park
- The Mayfair Wine Tasting, run with Mayfair Liquors, which pairs wines from America and Europe with food from the neighborhood and supports Mayfair Liquors, in business since 1959
- The Shred-a-Thon at the Mayfair Plaza parking lot at 14th and Krameria
- Monthly board meetings, open to all residents
If you have moved in during the last two years and never attended one of these, this is the summer to fix that. The interior calendar is the ballast that keeps the neighborhood recognizable while the north edge is torn up.
How to read the neighborhood this summer
The honest version of the summer 2026 Mayfair story is this: the neighborhood a real estate portal shows you is a single polygon with a single median price, but the lived version has two north edges running on very different schedules, one steady western edge doing the walkable-retail work, and one interior program that has not moved.
Practically, that means:
- If your block is west of Colorado Boulevard, the summer feels like the end of something. Fencing on Colfax comes down in stages through spring and fall. Postino, Hopdoddy, and the AMC are effectively your default corridor.
- If your block is east of Colorado Boulevard, closer to Krameria, Leyden, or Monaco, the summer is the middle of something. Center-lane construction, staggered platform builds, and lane shifts continue through 2027. Catfish King's fall soft opening at 5454 E. Colfax is the first meaningful sign of what post-BRT Colfax will look like at that end of Mayfair.
- Regardless of which half you live in, the Mayfair Neighbors Inc. calendar and Mayfair Park are running unchanged, and the Mayfair Plaza corner at 14th and Krameria is doing exactly the everyday-errands work it has always done.
For homeowners considering listing this year, the split matters. A home two blocks off Colfax on the Eudora end presents differently in the fall of 2026 than a comparable home two blocks off Colfax at Krameria, and that gap is not a matter of finishes. It is the schedule of a bus rapid transit line, and it is worth pricing and staging accordingly.
