Lucile Plane Unit Overview
Plane Unit is at 904 FM 686, Dayton, TX 77535. TDCJ describes it as four miles north of Dayton on FM 686 off Highway 321 in Liberty County, co-located with Hightower and Henley on about 394 acres. The inspected page listed Senior Warden Rokeisha Briscoe and ACA accreditation since January 1999.
The unit came online in May 1995 and holds female inmates at J1 through J4, G1, G2, and transient levels. It is a state prison, not a county jail. Use the state locator and TDCJ visitation process for Plane Unit questions.
Lucile Plane Unit Capacity
TDCJ lists Plane Unit capacity as 2,296. That figure is part of the TDCJ footprint inside Liberty County, not the Liberty County Jail population. Plane is the largest mapped correctional facility in this build by listed capacity.
Because Plane is a state prison, its capacity and population should be read separately from the Liberty County Jail snapshot. A person can be arrested in Liberty County, held at the jail during the case, and later move to TDCJ after sentencing or state custody action.
Look Up Lucile Plane Unit Inmates
Use TDCJ Inmate Search with a name, TDCJ number, or SID number. TDCJ states that results include only current TDCJ inmates and are at least 24 hours old. If a woman was just arrested in Liberty County, search the county jail roster first. If she was sentenced or transferred to TDCJ, search Plane by unit through TDCJ results.
- Open the TDCJ search form.
- Enter last name plus first initial, or use TDCJ or SID number.
- Confirm the current unit in the profile.
- Use TDCJ visitation resources before travel.

The TDCJ page documents capacity, custody levels, medical services, and programs that do not appear in the county jail roster.
