The makeover gives the governor and state lawmakers new power over how infrastructure dollars are spent. Legislators will control up to 20 percent of the annual transportation budget - about $400 million this year. The law also creates a new transportation planning division that will submit the agency's budget to the governor.
But the bill signed by Perdue on Tuesday stopped short of his original proposal, which would have replaced the 13-member state transportation board elected by legislators with a new agency.
Republican leaders are hoping the changes help transform a dysfunctional bureaucracy that's lagging behind on badly needed road projects.
