The following detail drawings should be incorporated, where appropriate, into the traffic control plan for any short term work. 1. See Section 1.6— Bicycle and Pedestrian Considerations for additional guidance. 2. Stay alert for pedestrians and bicycle traffic and accommodate safe passage for them, as needed. 3. The work space should be protected from bicycle and pedestrian intrusion by using barricades or closely-spaced channelizing devices. 4. Maintain access to transit stops or clearly close a transit stop using barricades or channelizing devices. Bicycle Accommodation Diagram 5-6 Bicycle Accommodation Principles: 1. If a significant volume of bicycles can be expected and work closes a marked bicycle facility, or requires bicycles to share a travel lane, install a"(Bicycle) ON ROADWAY" sign (CW11-1) or the Bicycle symbol (W11-1) sign with an "ON ROADWAY" (OBW1-5) rider, in advance of the work area. 2. Install temporary signing off the paved shoulder, within the planter (buffer) strip, or share the width needed between the shoulder and the sidewalk, as available. 3. Signs are to remain in place until the surface is restored and the width made available for bicycle use. See Diagram 5-6 for typical bicycle signing placement.

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" (R9-11a) 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. eroexxx msm 116E^ 24x12 Type'W1' (Mount on B(II)LR) ROAD WORK AHEAD (Optional) iI &oewuxaoeEo aoEwux cine® cRaae HEnE �� UM OnIER SIM 24xl2 24x12 CLOSED Type'W7' Type,wv 24x12 (Mount on B(11)LR) (Mount on B(II)LR) Type wv (Mount on B(II)LR) eoEwux aosEO MIFM �RE pq6$IERE 24x18 Type W1' (Mount on B(19R) ROAD WORK AHEAD (OPWW Chapter 5 September 2016 Page 118 2011 Edition Lane Closure at Intersection with Flagging Diagram 620 Diagram 620 covers work within an intersection when normal traffic control must be interrupted. 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.
