For intermediate term situations, when it is not feasible to remove and restore pavement markings, the channelization must be made dominant by using a very close spacing. This is especially important in locations of conflicting information, such as where traffic is directed over a double yellow centerline. In such locations a maximum channelizing device spacing of 0 feet is recommended. The 0 foot channelizing device spacing recommendation is intended for the area of conflicting information and not the entire work zone. 5. control by CW3- "YIELD AHEAD" symbol signs for one lane two-way traffic control operations should be limited to work spaces less than 0 feet long and roadways with less than 000 ADT.
