TxDOT has proposed various improvements for the segment of FM 664 in Ellis County between US 287 in Waxahachie to Westmoreland Road in Ovilla, TX. The proposed project will transform the two lane, rural roadway into a four lane, urban roadway with a raised median. Additional improvements include the elimination of 90 degree turns and the construction of 6-foot wide sidewalks. The project received environmental clearance in the fall of 2020. The next steps for the project are the acquisition of approximately 87 acres of right-of-way.
