If you drive east on Grady Niblo Road past Mountain Creek Parkway, you're on a four-lane divided road that sits inside right-of-way set aside for six lanes. Then it stops. The pavement ends at the Chewy warehouse driveway at 7243 Grady Niblo, and past that point the road exists only on the city's Thoroughfare Plan.
This year Dallas redrew that line. The new plan treats the road the Estates at Grady Niblo is named for as two separate roads. West of that driveway it serves the warehouses. East of it, the city wants a slower, narrower street, designed to make long-haul trucks look for another route.
Where the Four Lanes Stop, and Why
The Estates at Grady Niblo sits on the south side of Grady Niblo Road, west of Kiwanis Road. City plans from 2017 show Old Settlers Way, Founders Court, Nature's Way, Preservation Lane, Austin Chalk Road and Trailblazer Way running through its phases. Head east along the same road and past Mountain Creek Parkway, the corridor turns industrial.
That industrial stretch got its shape from distribution buildings. The Dallas Morning News reported in 2016 that Mountain Creek Distribution Center I, at 7343 Grady Niblo Road, was finished that year and fully leased when it sold. Next door, Chewy's fulfillment center began receiving shipments at the end of February 2017, according to D Magazine.
The city's 2026 staff packet describes this built segment as a four-lane divided road inside 107 feet of right-of-way. That width matches the road's designation as a standard six-lane divided principal arterial. Until this year, the Dallas Thoroughfare Plan called for that same six-lane design all the way east to Merrifield Road.
What the 2026 Amendment Changes
The request came from The Potter's House of Dallas, Inc. It covers only the unbuilt part of Grady Niblo Road, from 3,650 feet east of Mountain Creek Parkway to Merrifield Road. On the City of Dallas Legistar record for file 26-1804A, the August 25, 2026 council item shows the hearing closed and the item approved. The "Final action" field on that page is still blank.
| Previous designation | 2026 designation | |
|---|---|---|
| Road class | Standard six-lane divided principal arterial | Minimum four-lane divided minor arterial |
| City code | S-6-D | M-4-D(A) |
| Right-of-way | 107 feet | 80 feet |
| Alignment | Original plan line | Shifted south |
The reason is Capella Park. The new-urbanist community sits near West Kiest Boulevard, between Mountain Creek Parkway and Spur 408, next to Dallas Baptist University and The Potter's House. The city says its planned expansion should add about 325 residential lots. The developer also plans to move the road's path south to put more distance between it and planned homes, and roundabouts are anticipated in the design. A Traffic Impact Assessment submitted by the applicant concluded that four divided lanes can handle future development, and city staff recommended approval.
Why the Boundary Moved East of Mountain Creek Parkway
The first version of this amendment started at Mountain Creek Parkway itself. That version got through the Thoroughfare Committee on February 6, 2025, and the City Plan Commission on May 8, 2025. When it reached City Council on June 25, 2025, the council sent it back.
The city's background summary explains why. A warehouse stakeholder objected to cutting the right-of-way width. The revised application moved its western edge east, leaving out the existing warehouse properties and the built road that serves them. The amendment area now matches the Capella Park expansion boundary. The new version went through the same steps again:
- June 25, 2026: The City Plan Commission Thoroughfare Committee approves the revised application.
- July 23, 2026: The City Plan Commission follows the committee's recommendation.
- August 25, 2026: City Council holds the public hearing, and the record shows the item approved.
So the line on the map follows land use. The road keeps its full 107-foot width wherever warehouses rely on it. The narrower design starts where the city expects houses.
What the Roundabouts Are For
The June 2026 Thoroughfare Committee briefing is direct about the goal. It says the changes respond to "community concerns about the potential for high vehicle speeds and truck traffic on Grady Niblo Road once the unbuilt section is connected in the future." It also says roundabouts would "promote traffic calming and discourage use of the roadway by large interstate trucks."
The worry is specific. Today Grady Niblo dead-ends, so warehouse trucks can only get in and out through Mountain Creek Parkway. Once the road connects through to Merrifield Road, it becomes a possible through route, and the design is meant to make that route unattractive to big rigs. The briefing also says the southern shift leaves room for more homes to be built north of the future road. The same document says the corridor is a Mixed-Use Street under the city's Complete Streets Design Manual and is not on the 2025 Dallas Bike Plan.
Activity on the warehouse side has also changed. In March 2025, the Dallas Morning News reported that Chewy was cutting more than 670 jobs at its Dallas fulfillment center. Coverage at the time said the site would stay open at substantially reduced capacity. The new design rules for the eastern half don't depend on how busy any one tenant is. They apply to whoever uses those buildings next.
The Road Work You'll Notice First Is on Camp Wisdom
The Grady Niblo extension is still a plan. The construction zone on Camp Wisdom Road is already there. The city is rebuilding 2,550 feet of Camp Wisdom between FM 1382 and Mountain Creek Parkway into a four-lane divided road. The project adds curb and gutter, sidewalks, a shared-use path, street lighting and drainage, plus a traffic signal upgrade at FM 1382 and Camp Wisdom.
The finish date has moved. Earlier city records estimated July 2026. The City of Dallas bond program project page, last modified September 24, 2026, still shows the job under construction, with an actual start of March 18, 2024, and an estimated completion of March 31, 2027. If that date holds, the project will have run about three years.
The budget has moved too. Ed Bell Construction Company's contract started at $6,855,180.45. A February 11, 2026 council resolution added up to $359,413.28 to move an existing 12-inch water main, bringing the contract to $7,283,519.23 after two change orders.
New homes are going up along the same road. The NRP Group broke ground in November 2025 on a 360-unit workforce apartment community at West Camp Wisdom Road and Clark Road. It is planned with a gym, pool and dog park, and Multi-Housing News reported a target completion in the second half of 2027. On the current schedules, the rebuilt road should be finished several months before those homes open.
What Still Has No Date
The Grady Niblo extension has no construction start date and no completion date. The city says the road will be built with future phases of Capella Park, so its timing depends on when those phases move forward. The plan does fix how the road will be built when it comes: four divided lanes in 80 feet, a path shifted south of the old line, and roundabouts. The city records it at no cost to the city.
