Bus 93 from Pottstown to Norristown Is a good 90 minutes and physical length wise is pretty long, however the ride goes by relatively fast because it mostly goes in a straight line only detouring to stop at the Montgomery County Correctional Facility and Limerick Outlets and is only "slow" when going through Norristown and Pottstown. It runs once an hour seven days a week between 7 AM and 10 PM
