Driving west on Baltimore Pike through Springfield, Delaware County, Pennsylvania, one will reach a stoplight flanked by Springfield Square North and South.
A few dozen yards behind will be an exit from Springfield Square North which could, but rarely, disgorges traffic back onto the Pike. Why would it be used? It only allows right turns hence it merely puts a motorist in line for a light they would likely miss if he just used the main exit.
Now, if that driveway were an entrance, on the other hand, it would be used probably by more than half of those entering the center cutting down the snarl at the main entrance and bringing relief to those drivers who just want to pass on by.
