A Foot Apart

This is a bridge in Lancaster,Mass. If you are traveling south, the sign indicates that the bridge clearance is 11 feet.

But if you are traveling north, the sign indicates that the bridge clearance is 11 feet - 3.3528 meters.

The people traveling south are therefore leaving the north. These people of the north already know that 1' = .3048 meters.

However, the people from the south that are traveling north, need to know the height of their vehicle, within 4 decimal places! This is also a sign of the exactness that will be required of you as you travel further north.
