In this exercise, you will draw 700 m radius circular curves between each of the three tangent segments that you just drew.

1. On the Lines/Curves menu, click Curve Between Two Lines, select the first tangent line, and then select the second tangent line.

2. Press ENTER to accept the default, Radius, and then enter 700 m for the Radius.

3. Select the second tangent line, and then select the third tangent line.

4. Press ENTER to accept the default, Radius, enter 700 m for the Radius, and then press ENTER.

The three tangent segments are connected with circular curves to complete the bridge abutment alignment.
