East-West Northpark Drainage Under 494, UPRR Now Connected
1/17/2026 – Northpark Expansion Project contractors have now officially completed connecting drainage on both sides of Loop 494 and the UnionPacific Railroad.
By today, the work area had been completely filled in and leveled. See below.
Now stormwater west of Loop 494 has a path to the Kingwood Diversion Ditch and the San Jacinto West Fork.
Project Manager Ralph De Leon emailed the Lake Houston Redevelopment Authority Board yesterday to inform them. He wrote, “Just wanted to share that we’ve reached a milestone. The contractor poured the collar on the west side of the rail tracks yesterday, functionally connecting the 8’ x 5′ boxes coming from the junction box at the Shell Station and going underneath Loop 494 to the junction box west of the rail tracks.”
The bore under the tracks finished several weeks ago. The culvert shown above plugged the last gap.
De Leon did not indicate whether contractors sealed the last junction box with a Golden Spike.
Meaning of Milestone
With the east/west subsurface work completed, contractors can now begin building the bridge over the railroad tracks and Loop 494. De Leon concluded his email to the board with “We are officially there now.”
When complete Northpark Expansion will represent the first all-weather evacuation route from Kingwood for 78,000 people.
However, while reaching the milestone is a huge accomplishment, it will also mean some inconvenience next week.
Westbound Lane Closure Weekend of 1/23/26
On Friday, January 23, the eastbound entrance to Northpark from the northbound I-69 feeder road will be reduced to one lane eastbound. The constriction will start at 8 p.m. and remain until 5 a.m., Monday, January 26th.
During that time, the contractor will demolish and replace the remaining section of old roadway and install the last storm sewers at that location.
On Friday starting at 8PM, contractors will close one lane per the diagram above and begin demolition of the old concrete and an old 24″ storm sewer lateral pipe in the red L-shaped box.
On Saturday, they will replace the pipe, then begin grading and preparing for “Fast-Track” paving. Fast Track uses special techniques and materials that minimize traffic disruption. Contractors hope to begin pouring the concrete by 7-8PM.
On Sunday, they will stripe the newly constructed concrete and reopen lanes in their original configuration before the weekend.
The new lanes should reopen by 5AM Monday at the latest.
