Pedestrian Accommodation Principles: 1. If the work impacts the sidewalk or pedestrian facility, provide a safe, accessible path, where practical, in accordance with the requirements of the ADA. 2. If not practical to match the width of the existing pedestrian facilities, maintain a 4-ft minimum width. 3. Unless a reasonably safe route can be provided through the work space, pedestrians should be appropriately directed with advance signing to cross the road. Do not divert pedestrians into travel lanes. 4. Install pedestrian closure or detour signing on Type II barricades. Make every practical effort to satisfy the following: • If work closes a sidewalk or sidewalk ramp, close sidewalks at a point where an alternate crossing point or route can be provided. Minimize the amount of out-of-direction travel for pedestrians. • Use a combination of"SIDEWALK CLOSED" (R9-9), "SIDEWALK CLOSED USE OTHER SIDE" (R9-10), "SIDEWALK CLOSED AHEAD CROSS HERE" (R9-11), and "SIDEWALK CLOSED CROSS HERE" (R9-11 a)signing to direct pedestrians to an alternate facility. • Where there are business destinations between the nearest crosswalk and the work area, close the sidewalk at the business access nearest the work area, where practical using the SIDEWALK CLOSED sign. Include the SIDEWALK CLOSED AHEAD CROSS HERE sign at the nearest crosswalk prior to the closure. Chapter 5 September 2016 Page 56 2011 Edition Pedestrian Accommodation, Intersection Diagram 5-8 For work near an intersection, close crosswalks and/or sidewalks as necessary when safe passage cannot be maintained.

See the detail inset for the layout if using a single flagger to control both directions of traffic on low volume roads(less than 400 ADT)with good sight distance as discussed below. 1. Use truck-mounted flashing warning lights on work and protection vehicles. See Section 4.3—Lights and Lighted Signs for exceptions. 2. For added visibility, a truck-mounted arrow board or PCMS in caution mode may be used. 3. Flaggers at each approach are required if any of the following conditions exist: a. Night Operations. b. Work space is over 200 feet in length. c. Sight distance is less than 750 feet from each approach through the lane closure. d. Traffic volumes are greater than 400 ADT. 4. The length between the Flagger Ahead signs shall not exceed one mile. Use Diagram 340—Lane Closure with Pilot Car if exceeding one mile. 5. Cones should be used to outline the work space when curves or other roadway alignments prevent clear direction for the motorists to pass the work space safely. 6. Cones along the work space are recommended when posted speeds are 45 mph or greater, when working under heavy traffic or when travel lanes are narrower than 11 feet. 7. Extended queue signing (see Diagram 5-4)should be used when traffic queues extend beyond the initial advance warning sign. 8. When flagging near an intersection, the"Flagger Ahead" (CW23-2) sign should be visible to traffic entering from any side road. Additional advance warning and Flagger Ahead symbol signs may be placed on the side road(s). 9. Sign set-up and flagger placement shown may be used for intermittent full road closures of 20 minutes or less. 10. The"ONE LANE ROAD AHEAD" (W20-4) sign is optional and should be considered on high volume or high speed roads, or when extended queues are expected.

Work vehicles may or may not be in the work space. 1. During flagging, traffic signals shall be turned off. Contact the road jurisdiction for approval and assistance (see Chapter 3). 2. For multi-lane facilities, traffic approaching the intersection shall be reduced to a single lane on each approach. See Chapter 3 for information on flagging through intersections. 3. There should be one flagger for each approach. One flagger may control two adjacent approaches if sight distance, low volumes on side roads, and flagger position allows for safe operation and clear direction to motorists. For low traffic volume intersections (fewer than 400 entering vehicles per day), one flagger may be used. 4. The"ONE LANE ROAD AHEAD" (W20-4)sign is optional and should be considered on high volume or high speed roads, or when extended queues may be expected.
