s relied heavily on federal subsidies. The other bids included one that employed an autonomous bus using a combination of elevated and underground tracks; one that pitched an autonomous tram running along the U.S. Hwy. 281 right-of-way, and another that used a system of at-grade or elevated travel lanes running along McCullough Avenue. A plan offered by TriTrack Motors called for spending $24 million to build an elevated track for three-wheeled autonomous vehicles that could travel at up to 180 mph. In March 2022, the RMA board, led by then-Chairman Michael Lynd selected Boring’s bid over the others and created a development agreement to study the feasibility of the project. “Then we never heard back from them,” said Reggie Fountain, operations engineer for the Alamo RMA. Boring did not respond to the agreement, he said. That was two years ago. Agency staff followed up with Boring in February 2023. “They were reviewing it internally and they were going to let us know,” Fountain said. Further calls went unanswered, he said. “They just kind of ghosted us. So we essentially just assumed that it was dead and didn’t move further with it.” A Boring spokesman did not respond to a request for comment. The mobility authority had not spent money on the project or budgeted for it, so the agency has moved on, Fountain added. Funding that could have been allocated to the tunnel project is now committed to other transportation-related projects. For one, RMA is focused on improving Alamo Ranch Parkway, a $94 million project to ease major congestion in far Northwest San Antonio after a traffic congestion study bumped it into priority.
