The land around Denver’s 41st & Fox commuter rail station, just across the tracks from Sunnyside, is turning from industrial lots into apartments and a 41-acre mixed-use district called Fox Park, with a new 47th Avenue bridge planned to tie it to Sunnyside.
For most of Sunnyside’s history, its eastern edge was a working rail corridor lined with warehouses, yards and industrial buildings. The neighborhood looked west toward Federal Boulevard and south toward 38th Avenue, and few people had a reason to walk east.
That started to change when RTD opened the 41st & Fox Station in 2019. Since then, apartment buildings have gone up on both sides of the tracks, the old Denver Post printing site next to the station has been cleaned up for a large redevelopment, and the city has been working on new connections across the rail yards.
Jason Sirois is a Denver Realtor with FORM at Compass, whose office is at 1900 W 32nd Ave in Northwest Denver. Here is what has been built, what is underway, what is still only proposed, and what it means for homes on the Sunnyside side of the line.
Where is the 41st & Fox Station?
The station is at 4105 N. Fox St., an at-grade commuter rail stop served by RTD’s B Line and G Line. It is the first stop north of Denver Union Station, opened on April 26, 2019, and has about 500 parking spaces.
Sunnyside’s boundaries are Federal Boulevard on the west, West 38th Avenue on the south, I-70 on the north and the Union Pacific rail lines on the east. The station sits on the far side of that rail corridor, along Fox Street in the Globeville neighborhood, so for Sunnyside the station is a short walk or ride east rather than inside the neighborhood itself. Streets such as Jason Street, on the Sunnyside side, are only a few blocks from the platform.
What has been built near the station?
Most of the change so far is apartments. Denver Infill’s June 2024 roundup of the 41st & Fox area tracked these projects, with status as of that date:
| Project | Address | Homes | Status, June 2024 |
|---|---|---|---|
| Alloy Sunnyside (Prime West) | 4150 Jason St | 209 | Exterior complete, awaiting certificate of occupancy |
| 4155 Jason Street (LiveForward) | 4155 Jason St | 140 | Proposed, site plans filed |
| Fox Iron Works (RangeWater) | 4245 Fox St | 386 | Completed |
| Iota Fox Station (Highland Development) | 500 W 41st Ave | 148 | Completed |
| 4040 Fox Street (Central Street Capital) | 4040 Fox St | 224 | Under construction |
| Link and Pin (Rainer Development) | 4159 Fox St | 270 | Proposed |
| Abacus Upper Fox | 735 W 39th Ave | 331 | Proposed, in permitting |
| 805 W 38th Ave (Continental Realty) | 805 W 38th Ave | 425 | Proposed |

On the Sunnyside side, the Jason Street blocks closest to the tracks were industrial until recently. BusinessDen described the area in 2022 as largely industrial and trending residential, partly because of the bridge leading to the rail station, when a developer sought a rezoning for a five-story apartment building on Jason Street.
What is Fox Park?
Fox Park is the largest project in the station area. It covers about 41 acres on the former Denver Post printing site along Fox Street, next to the station and south of I-70. Part of the site was within one of Denver’s remaining Superfund areas, and the cleanup came first.
When the city and developers presented the plan in August 2024, Denverite reported it would include:
- 3,469 housing units, including hundreds of income-restricted homes
- A new World Trade Center Denver campus with offices, retail and restaurants
- A Virgin Hotel
- A 2,500-seat entertainment venue operated by AEG
- A 24,000-square-foot grocery store
- More than 14 acres of parks, open space and plazas, plus reuse of the old printing plant
Construction is in its early phases. Vertical construction on the first phase began on June 9, 2025, and the World Trade Center parking garage topped out in March 2026, according to Naked Denver’s project page. ENR reported in April 2026 that Phase 1 streets and utilities were complete and work on an underground garage and plaza was underway, as part of a buildout expected to take about 10 years. Other project descriptions cite a smaller first-phase housing count of more than 1,000 mixed-income units, so expect the numbers to shift as phases are approved.
How will Sunnyside connect to the station and Fox Park?
The rail yards are the main barrier between Sunnyside and the station area, so connections are the part of this story that most directly touches the neighborhood. Denverite reported in 2024 that new bike and pedestrian trails would link Sunnyside and Fox Park.
The bigger piece is a proposed bridge on West 47th Avenue. The Denver North Star reported that the city is moving forward with a two-lane, multimodal bridge linking the Fox Park site to the northeast corner of Sunnyside, estimated at about $28 million and funded partly through tax increment financing. A tunnel under I-70 was considered and dropped. Sunnyside United Neighbors sent a letter asking the city to design the connection around people walking and biking rather than cars. No construction date has been published.
What the city’s plan says for Sunnyside
Denver City Council adopted the Near Northwest Area Plan in January 2024, covering Sunnyside, Chaffee Park, Highland and Jefferson Park. The plan supports more “missing middle” housing, meaning buildings of roughly two to 19 homes such as duplexes, row houses and small apartment buildings, along with pedestrian- and bike-friendly corridors and support for local businesses along streets such as 44th Avenue.
An area plan guides future rezonings; it does not change zoning by itself. Each property’s current zone district, found on the city’s zoning map, still controls what can be built there today.
What it means for Sunnyside homeowners and buyers
For homes on the eastern blocks of Sunnyside, the change brings rail access to Union Station and, on the G Line, to Arvada and Wheat Ridge, along with more new buildings, more construction and more traffic nearby. How that balances out depends on the block. A home near the Jason Street apartments will feel the change more than one near Federal.
If you are buying, look at what is planned on nearby industrial parcels, not just what is there now, and check the zoning of the lots around you. If you are selling, the station, the new trail links and the Fox Park timeline are facts buyers ask about, and it helps to have them ready. Our Sunnyside community page covers the neighborhood more broadly, and our post on Columbian Elementary and Sunnyside school options covers another recent change.
