Purple Line

We’ve heard loud and clear from the public that communities in the border region and South San Diego County need faster connections to major job centers and schools in central areas of the region. This is why we’re planning many strategies to improve travel options, including a new transit line.

The Purple Line will be a high-speed, high-capacity transit route connecting San Ysidro and Sorrento Mesa through National City, City Heights, and Kearny Mesa. This will provide dependable transportation for low-income communities and an attractive alternative for others who wish to travel between these neighborhoods without driving. 

In recent years, we’ve already studied various options for rapid transit services along the I-805 freeway route, including a bus route, a Trolley route, and strategies to help connect people to transit stops. 

Right now, we’re studying opportunities and challenges for building a passenger rail route for the northern section of the Purple Line (from National City to Sorrento Mesa). This includes considering different types of trains and evaluating needed infrastructure. Next year, we’ll be asking the public to weigh in about the possible transit technologies, routes, where stops should be located, and more.
