Construction on the I-10 White Oak Bayou elevation project is grinding ahead west of downtown Houston, and drivers are feeling it. TxDOT crews are tearing out old ramps, pouring new pavement, and staging demolition across the work zone, all as part of a long-term plan to lift a stretch of the Katy Freeway above the bayou's historic floodplain. That translates to fewer lanes, rolling closures, and a whole lot of brake lights while the multiyear build-out continues.
According to KHOU, TxDOT briefed the public today, saying ramp work is underway, demolition is ongoing, and paving operations are continuing throughout the construction zone. The station's video update shows crews on both the mainlanes and the frontage roads and reiterates that traffic patterns will keep shifting as the project advances.
Per TxDOT, the elevation job covers roughly 1.8 miles from Heights Boulevard to I-45 and will reconstruct the I-10 mainlanes, the HOV lanes, and the Houston Avenue Bridge. The agency describes its core goal as to raise the I-10 mainlanes above the 100-year floodplain and notes that the plan also includes a two-mile, 10-foot-wide shared-use path along the south side of White Oak Bayou. TxDOT lists the estimated price tag at about $407 million and says the work is expected to take several years to finish.
TxDOT's project updates detail a major traffic switch that went into effect last fall, which reduced westbound mainlanes between I-45 and Houston Avenue to two lanes and closed several direct connectors for reconstruction. Those changes are expected to last into mid-2026 and, for some ramps, as late as mid-2028. "We continue to make great progress with the I-10 White Oak Bayou elevation project," TxDOT said, while warning that alternating entrance and exit ramp closures and nightly work will continue as crews build the elevated structures. Drivers will also see periodic full closures of frontage-road segments and temporary impacts to the White Oak Greenway while bridge work moves forward.
The rebuild is aimed squarely at preventing repeat flood shutdowns. Local reporting notes this stretch of I-10 has flooded about ten times since 1992, including during Hurricane Harvey, according to KPRC. The station reported that the project will replace the low-clearance Houston Avenue Bridge, frequently struck by oversize trucks, and add flood-control features such as a large detention basin beneath the elevated lanes. Officials say raising the freeway should help keep this piece of the Katy Freeway open during major rain events that previously left it impassable.
What Drivers Should Expect
For now, drivers can count on lane reductions, detours, and extended ramp shutdowns for the duration of Phase 1, and probably a few frayed nerves at rush hour. Crews recommend leaving earlier than usual or using alternate routes when possible. For the latest closure maps and nightly work schedules, check Houston TranStar, which posts real-time lane and ramp status for I-10 and nearby connectors. Officials are urging motorists to follow posted detours and to keep an eye on TxDOT Houston's social channels for short-notice changes while construction continues.
