Work zone typical traffic control plans (TCP)

Typical TCPs serve as guidance and may be modified with sound engineering judgment and familiarization with work zone policy and guidance. Typical TCPs are updated and new ones added over time, so check back frequently.

For unique roadway configurations or scenarios, develop project-specific or site-specific TCPs.

Traffic control plans must be accepted by the appropriate agency or agencies having jurisdiction and work zone speed limit reductions and advisory speeds must be approved per Chapter 5 in the Traffic Manual.

The zip folder contain the .dgn files. Currently, we are converting V8i MicroStation to OpenRoads. Several .dgn files have been completely converted, but those partially converted include a note above the sheet file to alert the user the conversion is incomplete.  Some files (like the original TC1-99 and 400-series TCPs) are still in V8i.

Note: Microstation V8i work zone resources are no longer updated and are now legacy.

Per WAC 468-95-010, WSDOT has now adopted the 11^th Edition of the MUTCD. For all new traffic control plans, be sure to update the temporary sign spacing and channelizing device spacing tables available only in Microstation OpenRoads cell libraries.
