Under the Comfort As Home program, officials asked over 500 businesses to open their bathrooms, and 288 agreed.
A Comfort As Home sign will be placed on the front of businesses that volunteer to join.
Tourists and local residents can use these restrooms for free, and they can also download an app to find restrooms nearby.
Larger signs have been installed on roads with heavy traffic to give directions and also allow companies to display free advertisements.
