Purple Line

MTA/Purple Line Transit Partners | Montgomery and Prince George's County, MD

The Purple Line is a 16-mile light rail line 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, Green and Orange Lines; at Bethesda, Silver Spring, College Park, and New Carrollton. The Purple Line will also connect to MARC, Amtrak, and local bus services. The Purple Line will be light rail and will operate mainly in dedicated or exclusive lanes, allowing for fast, reliable transit operations. Twenty-one stations are planned.

The project also includes certain other improvements:

• Bethesda Metro Station South Entrance
• Purple Line Mezzanine Connection
• Reconstruction of the College Park Metro Kiss-n-Ride and Bus Loop
• Capital Crescent Trail
• Montgomery County Green Trail
• University of Maryland Bicycle Path

As planned, the Transitway will be largely at grade with one short tunnel section, three sections elevated on structures, and several bridge structures. The Transitway will operate mainly in dedicated or exclusive lanes, serving five major activity centers just north of Washington, DC: Bethesda, Silver Spring, Takoma-Langley Park, College Park/University of Maryland, and New Carrollton. These activity centers are experiencing active development, and major commercial and residential projects are planned.

AEG is providing a variety of services for the Purple Line Light Rail Project, including construction support engineering services. Currently, AEG recently provided design for the micropiles supporting the tower crane foundation at the Manchester Place Station site. AEG utilized LPile software for the analysis of individual piles and drilled shafts. Our experienced engineers and technicians completed the analysis with complete precision and accuracy. AEG is currently designing a 170-foot long, one-span bridge at the Bethesda Metro Station. AEG’s involvement will also include engineering services for the design of various temporary works including formwork, falsework, retaining walls, and bridge erections plans. AEG will also be involved with providing peer reviews from other outside engineering firms.

In addition to the design of a 170-foot, one-span bridge at the Bethesda Metro Station, AEG just received notice for the design of an approximate 48’x13’ steel structure to support substation equipment at this same location.

Once completed, the Purple Line Light Rail will carry over 70,000 passengers a day. AEG is providing quality services to ensure that the project remains on schedule. Construction is estimated to end in 2021 and the 16-mile light rail is predicted to be able to begin providing services early in the year 2022.
