Major Road Closures Now Begin November 2 for I-45 Expansion
Closures related to the ongoing I-45 expansion project in Houston have been delayed and are now scheduled to begin next week. The original start date was postponed, meaning commuters heading into downtown Houston should prepare for significant road closures effective 9 a.m. on Monday, November 2, 2026.
US-59 Southbound Entrance Ramp at Webster Street to Close Until April 2027
One of the main changes involves the entrance ramp closure at US-59 southbound from Webster Street. This ramp will be completely shut from November 2, 2026, through April 2, 2027, as part of the highway construction for the I-45 expansion. Motorists are being encouraged to plan for alternate routes during this period.
Additional Downtown Street Closures Announced
Besides the entrance ramp, other closures are scheduled. Hamilton Street, from Pierce Street to Hadley Street, and Gray Street, between Chartres Street and Hamilton Street, will be closed. These closures are necessary for utility and infrastructure upgrades associated with the transportation project.
Storm Sewer Installation and Flood Mitigation Efforts
According to Mike Zientek, Public Involvement Liaison for the I-45 project, the closure on Hamilton Street is required for the storm sewer installation, which will drain to a new retention pond. These efforts are part of broader flood mitigation strategies to improve long-term conditions for drivers and residents in and around downtown Houston.
Plans for Traffic Management and Commuter Impact
To help with traffic management, crews will deploy yard signs featuring QR codes linking to updated closure maps, giving drivers advanced notice as the project proceeds. Zientek acknowledged the commuter impact caused by noise, dust, and detours, but emphasized that the completed project will deliver significant mobility improvement for Houston’s road network.
Long-Term Timeline for the I-45 Expansion
The transportation project has a long horizon. Zientek stated that the downtown portion should be completed by 2038, with the final project expected to finish in 2043. The full expansion aims to both ease traffic congestion and enhance flood resilience for the region.
