What is the minimum horizontal curve radius recommended for a design speed of 60 mph?

What is the minimum horizontal curve radius recommended for a design speed of 60 mph?

Step 1: Understand that a horizontal curve radius is the measure of how sharp a curve is on a road.
Step 2: Know that different design speeds require different minimum curve radii for safety.
Step 3: For a design speed of 60 mph, refer to guidelines or standards that provide recommended curve radii.
Step 4: Find that the recommended minimum horizontal curve radius for 60 mph is typically 500 feet.
Step 5: Conclude that using a curve radius of 500 feet will help ensure safe driving at that speed.
