A federal appeals court ruled Maryland officials donโt have to redo an environmental impact study, which allows construction on the Purple Line light-rail project to continue.
A three-panel judge at the Court of Appeals for the D.C. Circuit made the decision Tuesday, based on court filings that began three years ago.
Construction began in August after a court ruled work on the estimated $5.6 billion project 16-mile light-rail project that would connect with four Metro stations in Prince Georgeโs and Montgomery counties can begin during the appeals process.
According to Tuesdayโs appeal court opinion written by Judge Judith W. Rogers, a decline in Metro ridership wouldnโt affect the Purple Lineโs ridership numbers. In addition, Rogers said the opponents, or Friends of the Capital Crescent Trail of Bethesda criticized projection figures โwithout offering ridership numbers of their own.โ
Rogers wrote โthe courtโs analysis is flawedโ based on a decision made last year by U.S. District Court Judge Richard Leon for the Maryland Transit Administration to update an environmental study and the Federal Transit Administration to provide more information.

โEven if Metrorail ceased to exist โ an extreme and highly unlikely scenario given its centrality to transportation in the greater Washington metropolitan area โ light rail would still provide faster (and higher-capacity) eastโwest connections between major Maryland activity centers in Montgomery and Prince Georgeโs counties than would other alternatives, like bus rapid transit,โ he wrote. โLight rail also would promote new economic opportunities in the underserved low income and minority communities located between those centers, and provide better connections to non-Metrorail regional transit options, including the MARC train, the Amtrak railroad and local bus routes.โ
The Maryland Transit Administration will oversee the project to build 21 stations from New Carrollton in Prince Georgeโs County to Bethesda in Montgomery County. Four stations will connect as transfer stations with Metroโs Orange, Green and Red lines. Itโs scheduled to open in within five years.
Meanwhile, a second lawsuit filed by Friends of the Crescent Trail and two Montgomery County residents is pending in District Court. It claims the federal government improperly examined the project, especially since it committed $900 million toward it.
