Requirement for using channelizing devices (e.g. cones) to separate traffic from the work area for a work operation

New York does not have a specified requirement for this situation. If the work zone is continuously moving, cones may be impractical. In some cases the roadway may not be wide enough to support cones and the cones may be frequently displaced. However, paving jobs usually require cones to prevent traffic on the freshly placed pavement. There should also be a two-way traffic taper with cones just downstream of the flagger to guide traffic into the other lane.
