Houston TranStar to close the Webster ramp to I-69 South from November 2 to April 2, 2027. The work also affects Hamilton, Gray, and St. Emanuel Street.
Updated October 27, 2026.
Reconstruction work on I-45 in Downtown Houston will cause prolonged closures on an access ramp to I-69 and several nearby streets. Houston TranStar’s schedule as of October 27 now lists the closure of the I-69 South entrance from Webster Street starting on Monday, November 2, 2026, at 9 a.m., with an expected reopening on April 2, 2027.
The schedule represents a change from earlier announcements, which set the start of that restriction for October 27 and the end for March 26. TxDOT keeps the original dates in another section of its construction information, so the calendar may receive further adjustments.
The work is part of the North Houston Highway Improvement Project (NHHIP), which includes rebuilding highways and drainage system improvements in downtown Houston. The closures affect accesses and specific streets, but do not mean that all the main I-69 lanes will be closed during those months.
The Webster ramp to I-69 South would close on November 2
The Houston TranStar construction schedule calls for a complete closure of the entrance ramp to I-69 South from Webster Street starting at 9 a.m. on Monday, November 2.
The reopening is scheduled for 3 p.m. on Friday, April 2, 2027. The date is estimated and may change depending on progress of the work, weather conditions, or operational adjustments.
To merge onto I-69 South from that area, the detour published by Houston TranStar uses the following streets:
- Jackson Street, from Webster Street.
- McGowen Street, turning left.
- Hamilton Street, turning right.
- Elgin Street, turning right.
- Bagby Street, turning left.
- Continuation along Bagby Street toward Spur 527, which connects to I-69 South.
The detour for vehicles seeking to merge onto SH 288 South uses Jackson Street, McGowen Street, and Hamilton Street. From Hamilton, merging proceeds via the appropriate ramp, using the left lane.
Hamilton and Gray Street will have extended restrictions
The construction also includes closures on Hamilton Street, between Pierce Street and Hadley Street, and on Gray Street, in the vicinity of Chartres Street.
The TxDOT project information identifies for Gray Street the segment between Chartres Street and Hutchins Street. Notices released on October 26 described a closure between Chartres and Hamilton. This discrepancy in the published boundaries requires attention to the installed signage and the specific detour maps.
For Hamilton Street southbound, the announced alternate route uses St. Joseph Parkway, Jackson Street, and McGowen Street before returning to Hamilton.
On Gray Street, the announced detour for westbound traffic uses Chartres Street, St. Joseph Parkway, and Jackson Street.
The work includes the installation of large storm drainage conduits beneath Hamilton Street. These structures will connect with other hydraulic works in the project to improve the management of stormwater.
The notices from October 26 scheduled these restrictions from Tuesday, October 27 to March 26, 2027. The maps and periods remain subject to modification during construction.
St. Emanuel Street will be closed through March 2027
St. Emanuel Street also has a full closure planned between Jefferson Street and St. Joseph Parkway. Houston TranStar sets the expected completion date as Monday, March 1, 2027, at 3 p.m.
For northbound traffic, the detour uses St. Joseph Parkway, Chartres Street, and Jefferson Street before rejoining St. Emanuel.
To the south, the alternate route goes via Jefferson Street, Hutchins Street, and St. Joseph Parkway to re-enter St. Emanuel.
This closure will allow connection of a pumping station located near Chartres and Jefferson with the drainage system built under St. Emanuel Street.
St. Emanuel also maintains other restrictions at different intersections. Not all have the same duration or belong to the exact same phase of the project.
The works are part of the reconstruction of I-45 and I-69
The works belong to different segments of the North Houston Highway Improvement Project. Segment 3B-2 involves rebuilding and widening I-69 between SH 288 and I-45, while other phases include drainage work on streets east of Downtown.
The TxDOT NHHIP construction schedule keeps maps of the project segments, the restrictions, and their detours.
The project also contemplates infrastructure to convey stormwater to storage and pumping systems. The installation of underground conduits requires occupying portions of streets for extended periods.
The closures announced for Webster, Hamilton, Gray, and St. Emanuel correspond to distinct roads and accesses. Reopening at one location does not necessarily mean that the other restrictions have ended.
Houston TranStar maintains the detour and traffic-change calendar
Houston TranStar concentrates notices about highway closures, ramps, streets, and other construction restrictions across the metropolitan area.
The Houston TranStar construction registry allows reviewing scheduled closures, their timings, and available detours. The system distinguishes between planned works and active restrictions.
The Public Information Office of the Houston District of TxDOT handles inquiries about closures and road work at the 713-802-5076.

According to the schedule consulted on October 27, the Webster ramp to I-69 South is planned to close on November 2, 2026 and reopen on April 2, 2027. The calendars for the other streets should be verified separately as work continues.
