The Springfield Heights tunnel is crooked.
It's "crooked" because its an upward slope. Seems perfectly intentional.

I thought it was pretty clearly an incline
If you look at the beach in SH you'll see the land is quite higher than the rest of Springfield (as evidenced by the staircase). The staircase is 4 tiles wide and the tunnel shifts 4 tiles from the entrance to the exit. You can also see the inside of the tunnel sloping upwards from the outside road. It's a 4-tile incline to match the stairs on the beach
