PAT Uses Twitter to Release Changes Due to G20

The Port Authority is turning to Twitter to alert riders about last-minute route changes. Spokesman Jim Ritchie says the agency is looking for as many ways as possible to get information out about changes during the G20 Summit next month..."The difficulty is the authorities that are developing the security zone downtown aren't going to tell us where we can go and can't go until a week or two prior to the event. It creates a real time challenge for us. We have to get things out very quickly."

The Port Authority's Twitter identity is "pghtransit." Ritchie says people can get updates from their computers or on their cell phones. You can also sign up for updates through the Port Authority's web site. But since not everyone has online access, Ritchie says the Port Authority is also working with schools, businesses and other groups to spread the word about route changes.
