Project Overview

Maryland Purple Line Transit Project

The Purple Line is a 16.2-mile light rail transit line with 21 stations that will extend from Bethesda in Montgomery County to New Carrollton in Prince George’s County. It will provide a direct connection to the Metrorail Red Line at Bethesda and Silver Spring; Green Line at College Park; and the Orange Line at New Carrollton, as well as all three of the MARC rail lines and Amtrak’s Northeast Corridor at New Carrollton. This project will serve the existing dense residential neighborhoods, attractions, and employment and education centers by providing faster, more direct, and more reliable service.

In addition, passengers will benefit from access to all three MARC commuter rail lines as well as Amtrak’s Northeast Corridor at New Carrollton, reinforcing the Purple Line’s role as a regional transportation hub.

Beyond connectivity, the Purple Line is designed to serve the needs of dense residential neighborhoods and link major employment, education, and cultural centers. By offering faster, more reliable, and direct service, the project is expected to reduce travel times, ease traffic congestion, and promote sustainable mobility.

The Purple Line will also support economic growth and community development by improving access to jobs, universities, and attractions across Montgomery and Prince George’s counties. Local businesses, students, and commuters alike stand to benefit from a system that enhances accessibility and fosters greater regional integration.

Ultimately, the Purple Line is more than a transit project—it is a transformational investment in Maryland’s future, promoting equity, efficiency, and connectivity for generations to come.
