Nearly three months after President Joe Biden signed a roughly $1.2 trillion infrastructure bill into law, federal transportation officials say much of their work is on hold – stuck in limbo as a result of an unresolved congressional fight over federal spending. Some states, meanwhile, are putting off projects until Congress approves $9 billion in additional highway money. There is a race against the clock on Capitol Hill because the existing federal spending agreement is set to expire Feb. 18. By that point, lawmakers must pass another short-term measure, known as a continuing resolution, or come to a deal on a larger plan. If they don’t, the U.S. government – public-works projects and all – would come to a halt. If lawmakers can’t agree on a year of spending, transportation groups are urging Congress to include special provisions to unlock the infrastructure money as part of any short-term deal.
