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. The rail line will connect to MARC, Amtrak, and local bus services and will operate mainly in exclusive lanes, allowing for fast, reliable transit operations. Twenty-one stations are planned.

American Engineers Group, LLC (AEG) is providing a variety of services for the Purple Line Light Rail Project, including construction support, geotechnical engineering services, and surveying services. AEG provided design for the micropiles supporting a tower crane foundation at the Manchester Place Station site. Our experienced engineers and technicians completed the analysis with timeliness, precision, and accuracy. AEG also designed a 170-foot long, one-span bridge as well as a 48-foot x 13-foot steel structure to support substation equipment at the Bethesda Metro Station.

AEG recently developed engineering drawings for the partial demolition and subsequent renovation of a multi-story apartment building required to clear Right-of-Way for the Purple Line construction.

AEG also provided surveying services for an as-built survey of the existing CSX Railway lines located at four locations of the project to determine the clearance from the existing top of rail of the CSX tracks to the bottom of the proposed Purple Line Light Rail. Upon completion of the fieldwork, AEG provided detailed CADD/text file data.

AEG’s ongoing involvement includes engineering services for the design of various temporary works including formwork, falsework, retaining walls, and bridge erections plans.

Once completed, the Purple Line will carry over 70,000 passengers a day. AEG is providing quality and timely services so that the project remains on schedule. Construction is estimated to end in 2021 and the light rail is scheduled to begin providing services in 2022.
