The Northeast Corridor rail line planned between MiamiCentral and Aventura was originally estimated to cost $538M.
Now, the estimated cost has increased 72% to $927M, according to the SFBJ.
FDOT has agreed to increase funding for the project, the report said.
Originally, FDOT had committed $103.5m toward the project, (the remainder was to come from Miami-Dade and the federal government).
Miami-Dade sought an $236.47M in additional funding from FDOT following the cost increase. In response, FDOT said it will provide up to $200m in total funding, subject to legislative approval of the agency’s work program.
Miami Dade’s website currently lists the project cost at $682 million.
Earlier this year, the Biden Administration recommended the project receive $263.7 million in federal funding.
The 13.5 mile line is expected to be under construction by the end of next year, with a total of seven stations upon completion. An extension to Fort Lauderdale also being planned separately by Broward County.
Most county politicians now expect the service to be operated by Tri-Rail, the SFBJ report said.
