Route 91 History
SEPTA Route 91 was created on May 3rd 1986 as a means to access Graterford Prison from Norristown.
With the January 1987 change, service was enhanced to operate weekends, up from weekday only service.
On December 21st 1996, service on route 91 was reduced to Saturdays only, as ridership did not meet the demand of service otherwise.
With the 2014 spring changes, in preparation of construction for the new SCI-Phoenix facility, route 91 would be slightly rerouted in Trooper to serve both facilties.

In summer 2018, Graterford Prison was merged into the newly built SCI Phoenix, which would also mean SEPTA route 91 would serve the new facility (which was already on the same grounds).
Finally when the COVID outbreak hit in 2020, SEPTA would run the last buses on route 91, before discontinuing the route in April 2020.
Other routes with the same numbers
There was a second route 91, which replaced the first iteration of a route 122. Route 122 was created as a route that operated between West Chester and Oxford via Kennett Square. This line would be re-designated as route route 91 on July 6th 1982 but discontinued the next year on June 30th 1983.
