Overpasses ?
IIRC the road grade on the bridge that goes from the two Michigan peninsula's is 6% going up in ea direction. some cases, one can have some short "steep" grades on interstates. Local roads here In seattle ca be upwards of 24% which is the steepest I have found. 33% for a clients driveway on Lake washington going up to the main road.
