The administration of Maryland Gov. Wes Moore is proposing to tackle a multibillion-dollar, long-term budget shortfall by imposing drastic cuts on transportation spending that would slow highway construction, reduce transit service and increase the cost of airport parking, according to a summary of the plans.

The six-year plan, expected to be announced next week, calls for an 8 percent cut in the annual budgets of the state’s highway, transit, ports and airports agencies, along with the Motor Vehicle Administration (MVA). Construction budgets at most of the agencies would face even deeper cuts, according to the summary, parts of which were obtained by The Washington Post.
