8. On page 67, section 6F-5 f. Barricades (1) Design, revise the second sentence in the third paragraph to read:

The stripes shall be 6-inches wide, except where rail lengths are less than 36 inches, when then 4-inch-wide stripes may be used.

10. On page 71, section 6F-6 a. MARKINGS, revise number (3) to read:

(3) Markings shall be placed, along the entire length of any surfaced detour or temporary roadway, before such detour or roadway is open to traffic.

12. On page 78, section 6F-8 (2), add the following sentence to the last paragraph:

For stationary operations, the truck's parking brake should be set and, when possible, the front wheels turned away from the work site. Turning the front wheels should be based on specific conditions at the site such that the after-impact trajectory is into a safe area.

13. On page 78, section 6F-8.b, the third paragraph should be modified to read as follows:

On each side of the roadway only the first two yellow warning lights at the start of a continuous barrier should displays are not to be used on two-lane roadways.
