Why Northlake's Roads Are Being Fixed Out of Order, and What That Means for Your Commute

On a Monday at the end of July, Northlake Mayor Brian Montini drove out to FM 407 and I-35W at 4:25 p.m. and again at 6:30 p.m. He saw no backups in any direction, not even at Harvest Way. According to the Cross Timbers Gazette, he said he had "not observed these conditions at this time of day in over five years."

The project behind that drive cost about $2 million. It came from Denton County, not the state, and it is a stopgap. Northlake's local roads were planned on the assumption that state highway work would come first. That order flipped. For the next few years, relief will keep arriving as small, locally driven fixes, one corridor at a time. If you're comparing Northlake with nearby towns, the town-wide traffic story matters less than which of those fixes sits between a given street and the interstate.

The plan assumed the state would go first

The Mulkey Lane and Gibbs Road work near Pecan Square goes back to 2017. That year's development agreement made the developer responsible for widening those roads to four lanes in some sections. Northlake had hoped TxDOT's regional projects would be finished before that local work started. In February 2026, the Cross Timbers Gazette reported that they weren't. The state delayed FM 407, FM 1171 and I-35W work. It also changed its policy on bridges that cross an interstate at an angle, which directly affected Mulkey Lane's planned crossing of I-35W.

Montini described the result in that same article. "A significant amount of regional traffic is using Gibbs to avoid FM 407 and I-35W," he said, adding that the town "can advocate and coordinate, but we do not control TxDOT's schedules, right-of-way timelines, funding or design requirements."

Town Manager Drew Corn summed up the problem in July. "We have this challenge of aligning our local road system with the ultimate state road system, which is behind schedule," he told the Gazette.

Local roads built to feed a highway network that hasn't been built yet end up absorbing traffic they weren't designed for. Every section below follows from that.

What a $2 million restripe says about the bottleneck

Denton County's FM 407 Micro Breakout is the clearest example of a small fix working. It added right-turn lanes west of I-35W and through-lanes under the existing bridge. Ed Bell Construction Company built it for $2,058,939. Construction began Monday, April 6, 2026, and the county's September 2026 Precinct 4 project report lists it as substantially complete.

Denton County added one more adjustment on September 17. Westbound drivers coming from Argyle into Northlake can now go straight or turn right from the right lane. Once past the bridge, drivers continuing west still have to merge left, because the right lane becomes a turn lane into the Tom Thumb. The Gazette reported that the change was meant to get more drivers using the new lane under the bridge. Montini called it "incremental relief until the 407 breakout project begins."

That Tom Thumb opened at Harvest Town Center in March 2026, and it shows how closely retail and road capacity are now tied at this interchange. Harvest Town Center sits in unincorporated Denton County within Argyle's extraterritorial jurisdiction, not inside Northlake's town limits. That's a useful detail when you're reading addresses near the interchange.

Paint and lane assignments under one bridge changed how the afternoon peak felt. That points to a bottleneck concentrated at a few specific intersections, which explains why the next round of relief is being handled point by point.

The build order as of this fall

Here's where each piece stands. Every date is the most recent one published, and each is labeled with its source.

The big widening has a cost estimate but no construction money. Next spring's Breakout is funded but depends on TxDOT's letting calendar, which Montini told the Gazette "isn't the most punctual." He also said that getting the I-35W access roads all the way through is what allows full interchange reconstruction. At full build-out, that could mean up to 10 lanes under the bridges.

Each corridor has its own stopgap

While the state projects wait, Northlake and its neighbors have been fixing individual intersections. Each fix is tied to a different part of town, so the same morning drive can feel very different depending on where it starts.

Near Pecan Square, Mulkey Lane at Gibbs Road. In February, Montini laid out a phased plan, as reported by the Gazette. It started with restriping, then temporary signal trailers, then new pavement at the northeast corner for a protected, free-flowing right turn from westbound Mulkey onto northbound Gibbs. Permanent signals come after that, paid for by Pecan Square developer Hillwood under its development agreement. The town said it would likely pay for the extra right-of-way and lane expansion, and that a completion date would come once engineering and property coordination were finished.

Near Canyon Falls, Cleveland-Gibbs Road at Westbridge Drive. At its June meeting, the Town Council unanimously approved $600,000 toward construction under an agreement with the Canyon Falls developer. The work adds an intersection north of Westbridge Drive with a dedicated right-turn lane from the future Mulkey Lane, widens Cleveland-Gibbs at Westbridge, and adds a southbound left-turn lane. The developer is building two lanes, and the road's ultimate form is four. In July the town expected to finish in August, before school traffic picked up, according to the Gazette.

Along the Denton side, Robson Ranch Road. A City of Denton-managed project started August 10. It widens Robson Ranch Road from four lanes to five between Sagehawk Drive and I-35W and adds turn lanes, with work expected to run into early 2027, the Gazette reported. In an August column in the Gazette, Denton Mayor Chris Watts wrote that Denton County is providing the design and construction funding while the City of Denton manages construction. He also described a separate partnership with Northlake to add a northbound left-turn lane on Gibbs Road at Robson Ranch Road, expected by the end of 2026, along with temporary work at I-35W and Robson Ranch Road that was still being finalized with the county: widening to the bridge columns, restriping from two lanes to three, crash walls and a signal.

The Micro Breakout at FM 407 is substantially complete, Cleveland-Gibbs was targeted for August, Robson Ranch Road is under construction into 2027, and the Mulkey and Gibbs signals are waiting on engineering. The same stretch of months can mean relief in one corridor and an active work zone in the next.

Comparing two Northlake homes

Two homes a mile apart can depend on entirely different projects. A route that runs through the newly restriped FM 407 interchange is in a different position than one that relies on Mulkey Lane crossing I-35W, which is still waiting on a bridge affected by the state's design policy change. Before you settle on a street, a few practical checks will tell you more than any town-wide average:

1. Drive the route at the hours you'll actually use it, on a weekday, and note which intersection is the choke point.
2. Find that intersection in the table or corridor list above and check whether its fix is finished, under construction, or waiting on TxDOT.
3. Ask whether the route depends on a planned connection, such as Mulkey Lane over I-35W, that hasn't been built yet.
4. Check the latest Denton County Precinct 4 project report, which the county updates with letting dates and construction status.
5. Plan for construction along the way. The Gibbs-to-Gateway Breakout is a full rebuild from two lanes to six, so FM 407 will be a work zone after it lets.

A few common questions

Will the TxDOT widening fix FM 407 for good? It's the long-term plan, but as of the county's September 2026 report it had no construction funding against a $287 million estimate. The Town of Argyle has also asked TxDOT to reconsider six lanes through its boundaries, the Gazette reported.

When does the next big FM 407 project start? The Gibbs Road to Gateway Drive Breakout shows a March 2027 letting in the county's report. As of July 2026, Montini expected construction to begin in spring or summer 2027.

Is the area around the new Tom Thumb part of Northlake? Harvest Town Center sits in Argyle's extraterritorial jurisdiction in unincorporated Denton County, and Argyle oversees development and platting there.
