US public transportation agency Los Angeles County Metropolitan Transportation (Metro) has secured $100m in funding for the third and final section of Purple Line Extension Project.

The funding was awarded by the Federal Transit Administration (FTA) from its Fiscal Year 2018 Capital Investment Grants Program.

LA County Supervisor and Metro Board Chair Sheila Kuehl said: “We are very grateful for the positive and productive working relationship our agency has had with the Federal Transit Administration in working to advance the Westside Purple Line Extension Project.

“We are also pleased that our work toward obtaining a Full Funding Grant Agreement for this final section of the project is being favourably considered by the FTA.”

“We thank our legislative partners on Capitol Hill for their assistance in advocating for this nationally significant transportation project.”

Estimated to cost around $3.56bn, the final section of the project involves the construction of a 2.6-mile extension between Century City and Westwood/VA Hospital.

The section will include two new subway stations.

Metro has already applied for $1.3bn in funding under the FTA’s New Starts Program to build this project. It expects to secure the financing early next year.

Metro CEO Phillip Washington said: “We are pleased to be among the agencies to benefit from FTA’s advancing of these much-needed federal transit funds, and we thank our legislative partners on Capitol Hill for their assistance in advocating for this nationally significant transportation project.”

The previous two sections of the Purple Line Extension Project are currently under construction. Metro is expected to begin construction of the third section next year.

The overall nine-mile line is scheduled to open by 2026, ahead of the 2028 Olympics in Los Angeles.
