Chapter 6F - TEMPORARY TRAFFIC CONTROL ZONE DEVICES
Section 6F.78 - Temporary Markings

01 Temporary markings are those pavement markings or devices that are placed within TTC zones to provide road users with a clearly defined path of travel through the TTC zone when the permanent markings are either removed or obliterated during the work activities. Temporary markings are typically needed during the reconstruction of a road while it is open to traffic, such as overlays or surface treatments or where lanes are temporarily shifted on pavement that is to remain in place.

Guidance:

02 (DE Revision) Unless justified based on engineering judgment, temporary pavement markings should not remain in place for more than 30 days after the application of the pavement surface treatment or the construction of the final pavement surface on new roadways or over existing pavements.

03 The temporary use of edge lines, channelizing lines, lane-reduction transitions, gore markings, and other longitudinal markings, and the various non-longitudinal markings (such as stop lines, railroad crossings, crosswalks, words, symbols, or arrows) should be in accordance with the State's or highway agency's policy.

Standard:

04 Warning signs, channelizing devices, and delineation shall be used to indicate required road user paths in TTC zones where it is not possible to provide a clear path by pavement markings.

05 Except as otherwise provided in this Section, all temporary pavement markings for no-passing zones shall comply with the requirements of Chapters 3A and 3B. All temporary broken-line pavement markings shall use the same cycle length as permanent markings and shall have line segments that are at least 2 feet long.

Guidance:

06 All pavement markings and devices used to delineate road user paths should be reviewed during daytime and nighttime periods.

Option:

07 Half-cycle lengths with a minimum of 2-foot stripes may be used on roadways with severe curvature (see Section 3A.06 ) for broken line center lines in passing zones and for lane lines.

08 (DE Revision) For temporary situations of 3 days or less, for a two- or three-lane road, no-passing zones may be identified by using DO NOT PASS (R4-1) signs (see Section 2B.28) rather than pavement markings. Also, DO NOT PASS signs may be used instead of pavement markings on roads with low volumes for longer periods in accordance with the State's or highway agency's policy.

Guidance:

09 (DE Revision) If used, the DO NOT PASS signs should be placed in accordance with Section 2B.28 and DelDOT's Temporary Pavement Markings Policy.

10 If used, the NO CENTER LINE sign should be placed in accordance with Section 6F.47.
