Meet Your TMA
Who We Are
The 50 Corridor TMA (Transportation Management Association) is a nonprofit organization that's been serving the Sacramento Region since 1989. In 2025, we officially joined forces with the Sacramento TMA, which is the oldest TMA in the region and at one point one of the largest in the country. Together, we continue our mission to help people walk, bike, carpool, and use transit more.
We carry out our work in two contexts: workplaces, helping employees find their best commute, and residential communities, connecting people to resources that make getting around easier, less costly, and more enjoyable. Just think of us as a trip concierge—guiding each person to options that make travel less stressful and even joyful.
