Traverse lines MN, NO, OP, are centerlines of a portion of a proposed highway. Respectively, the bearings and distances are: MN, due North, 277.60 m; NO, N 26°40’ E, 107.00 m; OP, N 61°30’ E, 200.00 m. A previously designed compound curve connected these three tangent lines with PCC at Station 2+012.00.

Question
Traverse lines MN, NO, OP, are centerlines of a portion of a proposed highway. Respectively, the bearings and
distances are: MN, due North, 277.60 m; NO, N 26°40’ E, 107.00 m; OP, N 61°30’ E, 200.00 m. A previously designed
compound curve connected these three tangent lines with PCC at Station 2+012.00. It is desired to revise the system
into a single circular curve that will still be tangent to the three lines. (HINT: Convert the Compound Curve into a singular
Simple Curve, taking R1 and R2 as equal, taking N as new PC, and O as new PT).
