The Grand Parkway, also known as SH 99, is a 184-mile highway circling the greater Houston area. It is composed of eleven segments passing through seven counties, and is being completed in phases (some of which are now open). Sections H and I-2 of the project will traverse along the western portion of Liberty County, directly affecting the immediate Dayton, Liberty and surrounding areas.
