Capital Area Metropolitan Planning Organization (CAMPO)
The Capital Area Metropolitan Planning Organization (CAMPO) is the Metropolitan Planning Organization (MPO) for the Williamson, Travis and Hays Counties in central Texas. CAMPO was established in 1973 and is governed by the Transportation Policy Board (CAMPO Board) comprised of state, regional and local officials.

The purpose of CAMPO is to coordinate regional transportation planning with counties, cities, the Capital Metropolitan Transportation Authority (Capital Metro), the Capital Area Rural Transportation System (CARTS), Texas Department of Transportation (TxDOT) and other transportation providers in the region and to approve the use of federal transportation funds within the region. The two main products of CAMPO are the Long Range Transportation Plan (20+ years), the CAMPO Mobility 2030 Plan and the short range program, the Transportation Improvement Program (TIP). The CAMPO planning area encompasses all of Hays, Travis and Williamson Counties.

Texas Department of Transportation - Austin District
The TxDOT District Office is responsible for the planning, building and maintenance of the interstate and state highway road system in 11 Central Texas counties, including Williamson County. 

Central Texas Turnpike System
The Central Texas Turnpike System (CTTS) is a new transportation system that will improve overall traffic mobility, facilitate access to regional services, and increase travel safety for Central Texas residents, workers, and visitors. The system will initially consist of the 2002 Project, which includes three elements: SH 130 (49 miles), which begins north of Georgetown, Texas and runs to US 183 in southeast Travis County (extending to I-10 when funding becomes available); SH 45N (approximately 13 miles), from Ridgeline Blvd. west of US 183 to SH 130; and the Loop 1 Extension (approximately three miles), which runs from FM 734 (Parmer Lane) to SH 45N. The system will also include any future projects added to the system under the Texas Turnpike Act, as well as other roads, bridges, or other toll facilities for which the Texas Transportation Commission has responsibility and is collecting tolls.

Central Texas Regional Mobility Authority (CTRMA)
The Central Texas Regional Mobility Authority is a local, independent government agency created to improve the regional transportation system by implementing innovative solutions that reduce congestion and create transportation choices that enhance quality of life and economic vitality.

The Mobility Authority is the state’s first Regional Mobility Authority (RMA), created in January 2003 to serve Travis and Williamson counties. Texas RMAs were enabled by the Legislature as part of a package of initiatives to meet the state’s various transportation needs in new, better and more efficient ways.
