Overnight Katy Freeway closures begin for White Oak Bayou project

Motorists on westbound I‑10 toward downtown encountered a full closure of the Taylor Street exit when TxDOT shut the ramp at 9 p.m. April 7; the agency kept that exit and several other westbound ramps closed overnight and scheduled reopenings by 5 a.m. each night through the early morning of April 9. Drivers were directed to detour to the Patterson Street exit to make a U‑turn and use the eastbound frontage road to reach Taylor Street, while the Louisiana Street to westbound I‑10 movement was detoured via Franklin and Travis streets to I‑45 northbound. The I‑45 northbound connector to I‑10 was also closed, forcing motorists to continue to I‑610 West before returning to I‑10 during the nightly work window.

The overnight closures are part of TxDOT’s 1.8‑mile I‑10 White Oak Bayou Elevation Project, which will raise the westbound mainlanes above the 100‑year floodplain, rebuild HOV lanes, remove and reconstruct the Houston Avenue Bridge, and add a detention facility beneath the elevated roadway. TxDOT began major construction activity in early January 2025 following a ceremonial groundbreaking on January 18, 2025, and has framed the multi‑phase traffic switches and nighttime closures as necessary to limit daytime disruption. Trade reporting and TxDOT documents put the prime contract in the roughly $400 million range, with Webber LLC identified as the low bidder in the $407M–$408M band.

Commuters who regularly use the Heights/Main Street corridor and commercial drivers on the Katy Freeway freight route will feel the changes most immediately: TxDOT has counted roughly 10 flood events that forced closures on this stretch since March 1992, a primary rationale for elevating the roadway and building a roughly 26‑acre detention feature under the new alignment. The agency describes I‑10 as a critical multi‑state freight corridor and says the elevation work aims to reduce repeat storm closures that have disrupted goods movement and local commutes.

For drivers calculating the near‑term hit in minutes and dollars, use the posted detours and plan conservatively: the Patterson U‑turn/frontage‑road detour to reach Taylor Street replaces a direct exit with a route that typically runs on lower‑speed frontage roads and adds stop‑and‑go maneuvers. Using a conservative fuel model — a 25 mpg sedan and the Houston retail regular gasoline price of about $3.75 per gallon for the week of April 6, 2026 — each extra mile of detour costs roughly $0.15 in fuel. If a detour tack adds 3–6 extra miles round trip, expect roughly $0.45–$0.90 in fuel and an additional 7–15 minutes of travel time at typical frontage‑road speeds; larger vehicles and congestion during lane reductions will increase both time and fuel cost. These are modeled estimates based on the posted detour routes and regional fuel data.

The closures came days after the U.S. Army Corps of Engineers and the Harris County Flood Control District celebrated completion of the larger White Oak Bayou Federal Flood Damage Reduction Project, a separate effort delivering more than 15 miles of channel work and nearly 1 billion gallons of detention. Lt. Col. Darryl Kothmann said at the ribbon cutting, "The drainage reservoirs of this project will hold enough water to fill nearly 1,500 Olympic swimming pools," framing the federal work as a complement to TxDOT’s highway elevation. Local officials including Mayor John Whitmire, Harris County Commissioner Rodney Ellis, and HCFCD Executive Director Dr. Tina Petersen joined the ceremony; TxDOT leaders including Commissioner Steve Alvis and Executive Director Marc Williams have emphasized the project’s resiliency and freight benefits.

TxDOT’s traffic phasing will continue through multiple switches and lane reductions into 2028, with near‑term reductions of westbound through lanes between I‑45 and Taylor Street anticipated into the summer of 2026. Drivers who travel the Heights, Studemont, and Main Street corridors should follow posted detour signage, allow an extra 10–20 minutes for overnight commutes affected by ramp closures, and consider alternate morning approaches into downtown if they rely on the now‑intermittently closed connectors and ramps. TxDOT and project outreach have scheduled a pre‑recorded update on April 9 and an in‑person public meeting April 14 for neighborhood questions and formal comments as the multi‑year work continues.
