Mecklenburg County voters on Tuesday voted yes on an increase in the sales tax to fund a nearly $20 billion transportation plan that area leaders have spent more than five years working to win approval for.

With nearly all precincts reporting, the vote was 52.28% for and 47.72% against.

The sales tax on most items, except for food, medicine and some other categories, will rise 1 percentage point in Mecklenburg, to 8.25%

The vote caps off a push that began more than five years ago, and represents the biggest single source of new infrastructure funding in the region’s history. But question marks remain — such as whether the federal government will pick up any of the tab for the rail buildout — and the full plan will take decades to realize.

The funds will be spread between different transportation and transit modes: 40% of the new tax revenue will be dedicated to roads, bike lanes and sidewalks; 40% will be spent on rail transit, and 20% will be set aside for buses and new microtransit.
