616.8.1 Temporary Traffic Control for Contract Plan Sheet Development

Each work zone is different and requires different temporary traffic control (TTC) plans. For contract plan sheets, MUTCD (2009) Chapter 6H, provides the typical applications (TA) to develop TTC plans and for in-field modifications as directed by the engineer. TAs should be altered, when needed, to fit the conditions of the specific work zone. See EPG 237 for additional plan sheet guidance.

References to work vehicle or shadow vehicle made in the MUTCD will be considered incidental and should be left off TTC plans.

When optional items are referenced in the MUTCD, the contractor may at their discretion utilize the items as incidental, unless they have been added to the TTC plans as a requirement, and applicable pay items will apply. Field adjustments as determined by the engineer will result in adding the pay items via a change order.


616.8.2 Temporary Traffic Control for MoDOT Employees

These TAs are intended for the use of MoDOT employees. Before each work shift, all employees are required to participate in a pre-shift safety briefing. During the briefing, the applicable TAs should be printed out and then discussed to know the procedures to follow for the day’s work. This should include the risk-based assessment (RBA). The TAs shown in the EPG are considered current.

616.8.2.3 Examples of Highways

Divided Highway: Highway with physical separation of traffic in the opposite direction.
Median Separation
Median Separation with Guard Cable
Barrier Wall Separation
Undivided Highway: Highway with no physical separation of traffic in the opposite direction.
Undivided Highway
Multi-lane Undivided Highway

616.8.2.4 Recommended Advance Warning Sign Minimum Spacing

Table 616.3.4, Recommended Advance Warning Sign Minimum Spacing
Speed Limit1, mph Sign Spacing2, ft.
Undivided Highway Divided Highway
up to 35 2003 2003
40 to 45 350 500
50 to 55 500 1000
60 to 70 1000 SA-1000
SB-1500
SC-2640
1 Speed limit is based on posted speed limit.
2 Sign spacing may be adjusted, normally by increasing it, to accommodate field conditions and visibility.
3 For urban low speed, minimum recommended spacing in MUTCD is 100 ft.


616.8.2.5 Recommended Taper Length and Spacing

Table 616.3.5, Recommended Taper Length and Spacing

up to 35 70 245 356 406
40 to 45 150 540 406 806
50 to 55 185 660 507 807
60 to 70 235 840 607 1207
1 Speed limit is based on posted speed limit.
2 Taper lengths may be adjusted to accommodate crossroads, curves, intersections, ramps or other geometric features.
3 Channelizer spacing may be reduced to discourage traffic encroachment.
4 Based on 10 ft. shoulder width.
5 Based on 12 ft. lane width.
6 Spacing reduced to 1/2 at intersections.
7 Spacing may be reduced to 1/2 at intersections.
