VIA Rapid Green Line

What is Advanced Rapid Transit (ART)? 

Advanced Rapid Transit, or ART, is a high-quality, modern public transportation system that’s designed to move more people faster and farther. 

ART systems deliver fast, frequent, and reliable public transit service, with vehicles traveling in dedicated lanes outside regular traffic, using bus-friendly traffic signals, and offering off-board fare collection options for faster boarding.

An effective ART system is an important component to improving frequency and reliability, offering passenger comfort and more equitable access to affordable public transportation options.

The region’s first ART corridor, the VIA Rapid Green Line, connects points from the North and South sides. A second proposed ART corridor, the VIA Rapid Silver Line, connects the East and West sides.

San Antonio Business Journal: SA’s next-generation transit plan clears key hurdle

By W. Scott Bailey – Senior Reporter, San Antonio Business Journal

The Federal Transit Administration has given VIA Metropolitan Transit the green light to begin the final engineering phase for its first Advanced Rapid Transit, or ART, route.

It’s a pivotal milestone for the local transit agency and its efforts to deliver an alternative transportation plan.

The VIA Rapid Green Line corridor project, the first of two planned ART routes, will run from the San Antonio International Airport area along San Pedro Avenue and through downtown to Steves Avenue near Mission Concepcion. It will be the region’s first ART line, a new type of mass transit that typically utilizes dedicated lanes outside of regular traffic. 

VIA could reach a final funding agreement for the region’s first Advanced Rapid Transit route by end of 2024.

As VIA Metropolitan Transit continues to move forward to deliver the city’s first Advanced Rapid Transit corridor, local officials on Wednesday celebrated the opening of a Project Office designed to be an information hub for the community.

President/CEO Jeff Arndt was joined by Mayor Ron Nirenberg, former Mayor and U.S. Housing Secretary Henry Cisnero and VIA Board Chair Fernando Reyes at the project office to celebrate its opening. Though phased construction on the corridor isn’t set to begin until 2025, the office opened as a community resource, offering the opportunity to meet with project team members, give feedback and get updates about the transformative transit project. 



ART saves time
  • Pay before you board
  • Reliable 10- to 15-minute service all day
  • Bus-friendly traffic signals
  • Real-time route information
  • Boarding for people with all abilities
  • Level and all-door boarding
  • Connects more people to more places

MORE reliable travel

  • Dedicated bus lanes improve reliability, even as traffic congestion increases in the future
  • Arrival times are more accurate
  • Fewer cars on the road improves travel for everyone


VIA Metropolitan Transit’s Advanced Rapid Transit North-South Corridor Project has reached a critical milestone that will allow the agency to proceed with the final design and development of the project.

In May 2023, VIA received approval from the Federal Transit Administration on its federally required environmental study under the National Environmental Policy Act of 1969, known as NEPA.

VIA’s work under NEPA began in 2021 and included significant public engagement and technical review of the proposed project. The NEPA process concluded with the approval of an environmental document classified as a “Categorical Exclusion,” which means that the project has received its required environmental clearance.

This federal approval allows VIA to move the ART project forward into final design and construction with a planned launch in 2027. 

The documentation used in the NEPA process can be found below.
