WESTLAKE, La. — Drivers using Interstate 10 through Westlake can expect short but repeated delays as the Louisiana Department of Transportation and Development has scheduled alternating lane closures on both eastbound and westbound I-10 at Exit 25 for one night in early March 2026.
According to the agency, the alternating closures will take place from 8 p.m. Thursday, March 5, 2026, through 5 a.m. Friday, March 6, 2026, at Exit 25 in Westlake, affecting both directions of travel.
The work is weather permitting, meaning rain or other adverse conditions could delay or alter the schedule.
What Drivers Can Expect
The closure pattern is designed to slow traffic, not shut the interstate down for the entire night.
- Location: I-10 Eastbound and Westbound at Exit 25, Westlake
- Dates: 8 p.m. Thursday, March 5, 2026, to 5 a.m. Friday, March 6, 2026
- Pattern:
- Closures in 15-minute intervals
- Followed by a minimum of 30-minute openings to allow traffic queues to clear
In practical terms, traffic in each direction can be brought to a stop for up to 15 minutes at a time, then released for at least half an hour before the next closure begins. This alternating schedule is intended to give construction crews safe access to the work area while limiting long backups.
The Louisiana Department of Transportation and Development has not announced any full detour route because the interstate will periodically reopen, allowing vehicles to pass through the work zone between closures.
Purpose Of The Closure: Horizontal Boring Inspection
Officials say the overnight work is necessary to conduct an inspection of horizontal boring under the roadway.
Horizontal boring, sometimes called horizontal directional drilling, is a construction method in which crews drill a tunnel or passage underground without digging an open trench on the surface. It is often used to install or inspect utility lines, such as water, sewer, communications, or electrical conduits, below highways, railroads, or waterways.
Inspecting this underground boring is important to:
- Confirm the boring path and condition under the pavement
- Check for any issues that could affect the integrity of the roadway
- Verify that underground work meets safety and engineering standards
Because the boring runs beneath the travel lanes of I-10, inspectors and equipment must operate near or within the roadway, making temporary lane closures necessary for worker and driver safety.
Why The Work Is Scheduled Overnight
The interstate closures are set during overnight hours, when traffic volumes are typically much lower than during the day. By handling the work from 8 p.m. to 5 a.m., the Louisiana Department of Transportation and Development aims to:
- Reduce delays for commuters and commercial drivers
- Limit the impact on local businesses and daytime freight movement
- Provide a safer, less congested environment around the work zone
For many drivers, the biggest change will be the possibility of a brief wait if they arrive during one of the 15-minute closure windows.
Travel Tips For Westlake I-10 Drivers
Motorists planning to use I-10 near Westlake on the night of March 5–6, 2026, may want to:
- Allow extra time: Build in 15–30 minutes of additional travel time in case you encounter a closure.
- Travel outside the work window when possible: If schedules are flexible, drivers may avoid the 8 p.m. to 5 a.m. period.
- Stay alert in the work zone: Expect changing traffic patterns, stopped vehicles, and workers and equipment near the roadway.
- Follow posted instructions: Obey all signs, lane markings, and directions from law enforcement or flaggers.
These measures help keep both drivers and roadway workers safe while the inspection is underway.
Importance For Westlake And Regional Traffic
Interstate 10 is a major east–west corridor for Southwest Louisiana, linking Westlake and nearby communities with Lake Charles, Sulphur, and other points across Calcasieu Parish and beyond. Even limited short-term closures can affect:
- Local residents commuting for work, school, or appointments
- Commercial trucking moving goods across the region
- Regional travel between major cities along I-10
By scheduling the work overnight, using short 15-minute closure intervals, and maintaining at least 30-minute openings to clear queues, transportation officials are attempting to balance inspection needs with regional mobility.
The Louisiana Department of Transportation and Development advises that all work is subject to change based on weather or unforeseen field conditions.
