The Green Ribbon establishes strategies for corridor aesthetics and landscape enhancements along Texas highways surrounding Houston. This plan addresses existing infrastructure and future expansion needs of the growing urban area.

The project focuses on intensive landscape plantings and architectural treatments, improving aesthetics while addressing air quality and stormwater management concerns. The framework allows for large-scale improvements across a regional transect, accommodating local variation while maintaining cohesive standards.

A key achievement is the planting of over 2 million trees, enhancing the urban canopy. The plan’s flexibility enables local sub-districts to implement further enhancements through funding agreements with partners. The master plan serves as a living document, providing TxDOT with a foundation to incorporate evolving standards for Houston’s transportation infrastructure needs.
