Notes for Figure 6H-26—Typical Application 26 Closure in the Center of an Intersection
- All lanes should be a minimum of 10 feet in width as measured to the near face of the channelizing devices.
- A high-level warning device may be placed in the work space, if there is sufficient room.
- For short-term use on low-volume, low-speed roadways with vehicular traffic that does not include longer and wider heavy commercial vehicles, a minimum lane width of 9 feet may be used.
- Flashing warning lights and/or flags may be used to call attention to advance warning signs.
- Unless the streets are wide, it may be physically impossible to turn left, especially for large vehicles. Left turns may be prohibited as required by geometric conditions.
- For short-duration work operations, the channelizing devices may be eliminated if a vehicle displaying high-intensity rotating, flashing, oscillating, or strobe lights is positioned in the work space.
- Vehicle hazard warning signals may be used to supplement high-intensity rotating, flashing, oscillating, or strobe lights.
- Vehicle hazard warning signals shall not be used instead of the vehicle’s high-intensity rotating, flashing, oscillating, or strobe lights.
