The Ports-to-Plains Alliance Corridor is a planned four-lane highway that will allow companies to access less congested ports of entry into Mexico and Canada. It will be constructed from the Mexico border through West Texas and a 10 state region into Canada. An alliance of more than 165 organizations representing cities, counties, economic development corporations, chambers of commerce and the private sector have united to promote and support implementation of the corridor. The effort focuses on transportation improvements, but also addresses the relationship between the transportation system and economic drivers including energy, agriculture, manufacturing and distribution.

Once complete, the Ports-to-Plains Alliance Corridor will provide a complete four-lane route from San Angelo to markets south into Mexico and north through Colorado to markets in Alberta and Saskatchewan, Canada. The projected completion date for all four lane projects and relief routes is 2030.
