Construction of the Mustang Express Pipeline, a proposed 42-inch natural gas line by ARM Midstream/ARM Energy, is in the early planning and survey phase. The route is expected to run from Colorado County to Jefferson County, crossing multiple counties including Austin, Waller, Montgomery, Liberty, and parts of Harris County. Landowners along this corridor are beginning to see activity tied to survey access requests from right-of-way agents.
Once built, the Mustang Express will establish a new transmission corridor across Southeast Texas. Easements for a pipeline of this size typically range from 50 to 75 feet wide, with temporary workspace required during construction. These agreements can have long-lasting impacts on property use, making it essential to carefully review and negotiate any requests before granting access.
As the project progresses, landowners may face pressure to accept survey access or easement terms. While developers usually seek voluntary agreements, they may pursue condemnation through eminent domain if negotiations fail. Texas law guarantees property owners the right to just compensation and the ability to negotiate terms that safeguard their land, operations, and future use.

Counties currently identified include Colorado, Austin, Waller, Harris, Montgomery, Liberty, and Jefferson. Final alignments may adjust as surveys and permitting proceed.
Right-of-way agents are approaching landowners for survey access. These requests allow crews to enter property, collect data, and stake potential alignments.
Permanent easements are generally 50–75 feet wide for a 42-inch line. Additional temporary space is often needed during construction for staging equipment, trenching, and road or stream crossings.
The Mustang Express is in the pre-construction phase. Surveying, land acquisition, and route planning are active now. No definitive construction start date has been announced.
If voluntary agreements cannot be reached, pipeline developers may seek condemnation under eminent domain laws. This process is limited by Texas law, which guarantees just compensation to landowners.
