Gov. Bob McDonnell's plan to give an additional $4 billion to transportation projects was passed in the Virginia General Assembly Thursday.
Some Democrats have argued that McDonnell and the GOP-ruled House were maxing out the state's credit card. Approximately $3 billion of the plan is borrowed.
But supporters say low interest rates and construction costs outweigh risks from the debt -- and senators voted 66-32 to pass the bill Thursday.
The vote puts the measure back into McDonnell's hands. He has until late March to amend the bill or sign it into law. It would be the largest one-time infusion of capital for building and maintaining roads in decades.
