Work zone typical traffic control plans (TCP)
These Typical Traffic Control Plans (TCPs) are detailed drawings showing the layout of temporary road signs and devices to warn and guide traffic past, around and through the work site safely. Typical TCPs are not standard plans!
Typical traffic control plans (TCP) are generic and not intended to satisfy all work zone conditions and serve as guides. Typical TCPs may be modified with sound engineering judgment and familiarization with work zone policy and guidance. For unique roadway configurations or conditions, develop a project or site-specific TCPs.
Traffic control plans must have acceptance by the appropriate agency or agencies having jurisdiction. Work zone speed limit reductions and advisory speeds must have approval per Chapter 5 in the Traffic Manual.
Typical TCPs are being updated in Microstation to full-color and include up-to-date work zone cells. PDFs for newly revised TCPs are in color only, while PDFs for older updates also include black/white versions. Check back often as Typical TCPs are updated and new ones are added to the Library over time.
All users must update cells at least quarterly to help avoid using outdated cells.

Slow down on ice and snow.
It's easier to skid or lose control traveling at higher speeds. Give yourself more time to stop.
Carry chains, practice installing them.
Winter conditions could mean chains are required on your route. Practice putting them on your vehicle ahead of time.
Pack your winter car kit.
Carry extra supplies like warm clothing, ice scraper and brush, jumper cables and other emergency items.
