These funds will be returned to the municipalities, since they will be paid into the federal gas tax fund. These funds will be redistributed to municipalities that didn't have access to this fund while the program existed. The program began in 2004 and ended in 2014. Funds that were not used or that were returned because the projects cost less than expected will be transferred back to the municipalities.
On November 17th, 2016. See this statement in context.
