Notes for Figure 6H-22, 6H-22A(CA) and 6H-22B(CA) —Typical Application 22 Right-Hand Lane Closure on the Far Side of an Intersection
- If the work space extends across a crosswalk, the crosswalk should be closed using the information and devices shown in Figure 6H-29.
- The normal procedure is to close on the near side of the intersection any lane that is not carried through the intersection. However, when this results in the closure of a right-hand lane having significant right turning movements, then the right-hand lane may be restricted to right turns only, as shown. This procedure increases the through capacity by eliminating right turns from the open through lane.
- For intersection approaches reduced to a single lane, left-turning movements may be prohibited to maintain capacity for through vehicular traffic.
- Flashing warning lights and/or flags may be used to call attention to the advance warning signs.
- Where the turning radius is large, it may be possible to create a right-turn island using channelizing devices or pavement markings.
- See Figure 3B-14(CA) Page 3 of 3 for lane reduction markings. See Section 2C.40 for merge signs.
- Figure 6H-22 is appropriate for shortterm and intermediateterm duration where it is not appropriate to install temporary markings.
- Figure 6H-22A(CA) is appropriate for longterm duration.
- Figure 6H-22B(CA) is appropriate to avoid through movements from the right lane by first closing the right lane and then reopening it as a turn bay.
