Kingwood's Northpark Overpass Keeps Running Late. How It's Being Paid For Is the Part Buyers Miss.

"We have basically two ways in and out of Kingwood going east and west, and that's Northpark and Kingwood Drive," then-Mayor Pro Tem Dave Martin told the Lake Houston Redevelopment Authority board in January 2023, as Community Impact reported. That same meeting covered a project then estimated at roughly $52 million, with construction set to start that spring under Harper Brothers Construction.

The overpass is now about 75% complete. In a September 2026 update, Community Impact reported its cost at $76.8 million. Most of the money comes from a source that does not show up as its own line on a tax bill, and that funding model turns the real cost for buyers into time.

The finish line has moved four times in nineteen months

The Northpark Drive Overpass widens Northpark into a six-lane divided road between Hwy. 59 and Russell Palmer Road. It also adds a bridge over the Union Pacific tracks and Loop 494. The authority's capital plan gives one reason for the project, "excessive congestion attributable to regular roadway closures at Union Pacific Rail Road (UPRR) tracks." A Kingwood mobility study from 2014 counted an average of 20 Union Pacific trains a day with no set schedule. It put Northpark traffic at 35,000 vehicles a day between US 59 and Woodland Hills.

Here is how the expected completion date has moved:

1. February 2025. Third quarter of 2026, per Community Impact.
2. November 2025. Fourth quarter of 2026, in a later Community Impact update.
3. June 2026. Harper Brothers projected January 7, 2027, according to ReduceFlooding.com.
4. September 2026. Tom Broad, board chair of the Lake Houston Redevelopment Authority, said the project should be "substantially finished by April." No year was given.

Some of that schedule is out of the contractor's hands. On the authority's Northpark project page, the drill shafts for the bridge piers next to the railroad are on hold until Union Pacific approves the drill-shaft work plan. Once that approval comes, the page estimates about 10 days to install those piers. After that, the Loop 494 and Northpark intersection can partly reopen. The October 15, 2026 three-week schedule still lists the Bent 4 and Bent 5 drill shafts as "ON HOLD."

Some progress is already open to drivers. On June 23, 2026, traffic shifted onto the new surface lanes, which now run straight through from US 59 past Russell Palmer Road, ReduceFlooding.com reported. The bridge, the part that lifts traffic over the trains, is still being built.

Most of the money comes from value growth inside the zone

Most of this project is not paid for through a bond election or a new tax. It is paid for through Tax Increment Reinvestment Zone No. 10, which operates as the Lake Houston Redevelopment Authority. The Texas Comptroller's explanation lays out how a TIRZ works. The zone sets a baseline taxable value. Tax collected on any value above that baseline goes into a fund for improvements inside the zone, and tax on the base value still goes to the taxing units.

The overpass budget in the authority's 2027–2031 capital plan breaks down like this:

That total includes about $10.9 million for land acquisition. It is also about $1.1 million more than the $76.8 million Community Impact reported in September. Both are published figures, and both put the cost around $77 million.

The zone's history explains how Kingwood got here. The City of Houston's TIRZ 10 page says the zone was created to replace several municipal utility districts the City absorbed in the 1996 Kingwood annexation. It gave Friendswood Development a replacement way to finance water, sewer and drainage for subdivisions along the lake. A 1999 expansion let three more developers use the same financing. The boundary was enlarged again in 2011, 2014, 2018 and 2020. In many newer master-planned communities west and south of Houston, infrastructure debt is paid through a separate MUD rate on the tax bill. Kingwood's main infrastructure money moves through a zone that captures growth in value.

The authority's budget for the year ending June 2026, included in its June 2026 board packet, projected $12,507,592 in incremental tax revenue from the school district and $8,835,638 from the City. The City lists interlocal agreements with Humble ISD and Harris County for the zone. So a large share of the money building Northpark comes from the school-district share of the growth in value inside the zone. For a buyer, that changes the question. A homeowner does not see a new rate tied to this project. The tradeoff is the length of the work, and the work is funded as value inside the zone grows.

Phase 2 puts the next stretch of Northpark on a 2029–2030 timeline

The overpass is only the first phase. Phase 2 is a $72.7 million widening of Northpark to six divided lanes from Russell Palmer Road to Woodland Hills Drive. As of September, it was about 30% through design, and right-of-way purchases were set to begin this fall.

That right-of-way work is now on paper. TxDOT early-acquisition memos dated September 8, 2026 list the property owners along the corridor. On the Montgomery County segment, they include Northpark Fuel Depot LLC, Parkwood Baptist Church, Haven at Kingwood LLC and McFadden Properties. On the Harris County segment, they include Walmart Real Estate Business Trust, McDonald's Corporation, Speedy Stop Food Stores and AT Real Property LLC, among others.

The construction dates depend on the source. In November 2025, Community Impact reported construction running from October 2028 through 2030. The authority's 2027–2031 capital plan puts construction spending in 2029. Unlike the overpass, Phase 2 shows grant money in its budget, $18.841 million for each county segment. Community Impact has reported federal highway funding programmed for this phase.

Put the two phases together and Northpark is likely to be a work zone in some form for most of this decade. A buyer who closes this winter is buying into the tail end of Phase 1 and a few years of design and land purchases before Phase 2 construction starts.

Businesses on the corridor have already lived through one round of this. In late July 2025, Partnership Lake Houston and the Greater East Montgomery County Chamber started the "Northpark Needs You" campaign. It included a business directory to send customers to shops along the construction zone, as Community Impact covered. Skero's Furniture & Mattress, Megaton Brewery and Kenneth's Car Care were among the businesses named in that coverage. They are worth a stop next time you use the new surface lanes.

September's numbers give buyers time to plan around the construction

A slow construction calendar matters most when the market forces quick decisions. The latest local data shows Kingwood's market moving more slowly, too. Here are Community Impact's September figures for the two Kingwood ZIP codes, published October 7, 2026:

In September 2026, the two ZIPs moved in opposite directions on price. Both took longer to sell. Across Community Impact's six-ZIP Lake Houston, Humble and Kingwood area, active listings rose from 1,193 in September 2025 to 1,430 in September 2026. Inventory went from 4.7 to 6 months. Closed sales slipped from 256 to 237, and price per square foot edged up from $141 to $144.

These are one month of figures from a small number of closings, and no source ties them to the road project. Even so, both trends point in one direction. Homes in both ZIPs are taking longer to sell, and there are more listings across the area. That gives buyers time to check how a particular street reaches US 59 today, see which side of Russell Palmer it sits on, and look up whether a nearby commercial parcel appears on a Phase 2 acquisition list.

Questions buyers ask about Northpark

Does buying in Kingwood mean paying a separate tax for the overpass? The capital plan shows the overpass funded by TIRZ funds and a City of Houston contribution, and a TIRZ works by capturing tax on value growth above a baseline. Each property's tax bill depends on its own taxing units, so check a specific address with the appraisal district and a tax professional.

When will the bridge open? Officials said in September that it should be substantially finished by April, with no year given. The Union Pacific approval on the pier drill shafts is the dependency to watch.

Is Kingwood Drive part of this project? No. The overpass and Phase 2 cover only Northpark Drive, from Hwy. 59 to Woodland Hills Drive.
