Parsons Corporation (NYSE: PSN) announced that the Los Angeles County Transportation Authority opened Section 1 of the D Line Subway Extension project. The company served as lead designer for the 3.9-mile subway segment, which runs from Wilshire/Western in Los Angeles to Beverly Hills.

The extension includes three new underground stations at La Brea, Fairfax, and La Cienega. Parsons performed design management and final design work for the project, according to a company statement.

The D Line Extension project will ultimately extend the transit system westward for approximately nine miles under Wilshire Boulevard when completed. The project is being constructed in three sections.

"We are excited to see this extension of the D Line begin service for the community," said Mark Fialkowski, president of Infrastructure North America for Parsons. "This subway extension will improve commuter access for nearby neighborhoods and open access to cultural and art locations that had been previously limited."

The new section provides access to cultural institutions including the Los Angeles County Museum of Art, the Petersen Automotive Museum, and the Academy Museum of Motion Pictures. During development, Parsons worked with Metro, the cities of Los Angeles and Beverly Hills, and other stakeholders on station designs.

Parsons has experience with more than 450 rail and transit projects globally, according to the company. The Virginia-based infrastructure firm also has worked on over 10,000 miles of roadways and 4,500 bridges worldwide.
