The CTA calculates ridership by counting the customers who board a transit vehicle (bus or rail).
The Soldier Field Express route saw the largest increase in ridership with a 115.1% rise.
Bus and train traffic took a serious hit during the pandemic. The Metra, which provides service to many of Chicago's suburbs, saw a 97% decrease in ridership according to the Active Transportation Alliance. According to the Federal Transit Authority, Chicago's public transportation sector received $1.43 billion in bailout funds from the CARES act to combat the decrease in ridership.
While ridership hasn't returned to pre-pandemic levels, CTA's president Dorval R. Cart Jr. said weekday ridership has doubled since the initial shutdown and continues to increase.
