A Philadelphia transit workers strike ended just in time to help voters get to the polls.
A union representing almost 5,000 workers had been on strike for close to a week over health care coverage, wage increases and more.
Politicians feared the strike could keep thousands of voters from getting to the polls on Tuesday. African-Americans and low-income residents are especially reliant on the city's public transit system.
Pennsylvania also doesn't have any early in-person voting procedures.
In the negotiations, both sides agreed the deal was fair, though it still has to be ratified by each.
Hillary Clinton is counting on a big turnout in Philly to counter Donald Trump's support in Pennsylvania's more working-class and rural areas. Polling shows Clinton with an average four-point lead in the state overall.
