What tools does this page offer?
Read the curve table and tell me if the radii suit 45 mph.
Add a 1500 ft tangent to the end of the alignment. If the engine refuses, read the numbers out of the refusal, fix the profile, and try again.
Widen the travel lanes to 13 ft and show me the cross section at station 2500.
