DART Refinances Silver Line Construction Loan Written by Marybeth Luczak, Executive Editor Construction is under way for Dallas Area Rapid Transit’s $1.2 billion Silver Line Regional Rail project, a 26-mile double-track commuter rail alignment extending from Dallas-Fort Worth International Airport eastward to Shiloh Road in Plano, Tex. (Pictured: Josey Lane bridge work in Carrollton.) The U.S. Department of Transportation Build America Bureau has provided a $908 million loan for Dallas Area Rapid Transit’s (DART) Silver Line Regional Rail project, under the Railroad Rehabilitation and Improvement Financing (RRIF) program. It will refinance the original loan provided in December 2018. The proceeds will cover a portion of construction costs for the $1.2 billion project: a 26-mile double-track commuter rail alignment extending from Dallas-Fort Worth International Airport eastward to Shiloh Road in Plano, Tex. The move is expected to save DART $190 million in interest costs, and that savings could be used to address a funding gap for other projects in the future.
