00220.00 158 Section 00220 - Accommodations for Public Traffic Description
00220.00 Scope - This Work consists of maintaining facilities to accommodate Public Traffic through
and within the Project for the life of the Contract. Public Traffic includes motor vehicles, bicy cles, and pedestrians.
00220.01 General :
a.Beginning of Contractor's Responsibility - The Contractor's responsibilities for accommodating Public Traffic begin on the day any On-Site Work begins within the Project limits.
b.Abbreviations: PCD - Pedestrian Channelizing Device
c.Definitions: Work Area - The portion of the Highway closed to Public Traffic and set aside for workers, construction Equipment , and Materials. The Work Area is typically delineated by channelizing devices or separated from traffic using temporary barriers.
00220.02 Public Safety and Mobility - Provide for the safety and mobility of the public and:
a.General Requirements: Be responsible for damages according to 00170.80. Conduct Work at all times so there is the least possible interference with or hazard to the traveling public and the affected community. Locate stockpile Materials and park construction Equipment and vehicles that are not in active use a minimum of 30 feet from the Traveled Way . If this is not possible, protect the stockpile Material s, Equipment , and vehicles, with barrier or as directed. Provide and maintain safe temporary access to business and residence driveways, temporary intersections, and temporary connections with roads, streets, and bicycle and pedestrian facilities. Provide approved protection and delineation between each Work Area and Public Traffic . Allow emergency vehicles immediate passage at all times. Use portable changeable message signs (PCMS) according to Section 00222 . Do not impede the flow of traffic or close any lanes of traffic except as listed in 00220.40(e). Do not stop or hold vehicles on a Highway within the Project Site for more than 20 minutes. Do not block driveways for more than 2 hours unless otherwise authorized in writing. Do not close any lanes or pedestrian facilities until the area is signed according to the Plans and the requirements of this Section and Sections 00221 and 00222. Do not perform Work that restricts traffic access to and from both sides of the Traveled Way at the same time. Do not use temporary steel plating within the Roadway or Shoulder having a pr econstruction posted speed zone greater than 35 mph. Do not place Work Zone signs or sign supports that will block existing walkways or existing bikeways, except at the closure point of a walkway or bikeway. 00220.02 Do not stop or hold traffic inside a tunnel duri ng flagger control operations at any time. Delineate all business accesses with blue tubular markers on 10 foot maximum s pacing. Mark the access with 36- by-24 inch "BUSINESS ACCESS" (CG20 11) signs. Locate and install these signs as directed. When pipe b ackfill cannot be achieved by the end of a work shift and temporary plating is not in place according to 00405.46(e), provide additional temporary T raffic Control Measures as required by the Engineer and at no additional cost to the Agency.
b.Temporar y Pedestrian Accessible Route Plan - For the safety and accessibility of pedestrians , the T emporary Pedestrian Accessib le Route Plan shall provide and maintain TPAR for pedestrian pathway s impacted by construction or construction staging, and the following: TPAR shall meet the requirements of Part 6 of the MUTCD. For intersection Work that impacts the accessibility of pedestrian routes through or around the Work Zone, limit impacts to one corner of an intersection at a time, unless otherwise shown. For all sidewalk or curb ramp closures, install signs and other TCD as shown, and do the following: • Limit pedestrian detour lengths to three sides of a city block or 1000 feet, whi chever is less. • Close the sidewalk at a point where there is an alternate way to proceed, and provide signing and other TCD directing pedestrians to an alternate pedestrian route. • Place closure signing at the closure point, as shown. • Mount signs between t he panels of a Type II barricade or on a single- post temporary sign support, as shown. Place signs facing pedestrian traffic. For TPAR where the existing facilities do not meet the requirements of Part 6 of the MUTCD , provide additional TCM and pedestrian detour routes that, as nearly as is practicable, meet or exceed the level of accessibility of existing facility features. For TPAR where the existing facilities meet the requirements of Part 6 of the MUTCD: • Provide additional TCM and pedestrian detour routes with an approved, non- slip, 60 -inch minimum wide surface. • Where a 60-inch minimum width along the entire alternate pedestrian route is not possible, provide a minimum 48-inch wide route with a 60 by-60 inch passing space every 200 feet along the route. Protect pedestrians and delineate the pedestrian detour route by placing PCD, or other approved devices, between the pedestrian detour route and the W ork Area. Keep PCD in place, except as required for actual Work , until the permanent pedestrian facilit y is completed and reopened. Where the TPAR moves pedestrians vertically between a sidewalk curb and the Roadway surface, and for other similar sudden change s in elevation, provide or construct a temporary curb ramp according to Section 00228 or as shown. When Work briefly or intermittently blocks or restricts the use of a pedestrian route, and a temporary detour route is not practicable due to the short duration of the restriction, provide a temporary means of allowing pedestrian access through or around the Work Area. Means of providing temporary pedestrian accessibility may include, but are not limited to: • Temporarily suspending the Work and making the pathway passable. • Use of construction staff to guide pedestrians through or around the W ork Area. Keep existing pedestrian facilities open during non-work hours or continue to provide a TP AR. 00220.03 160 (c) Bicyclists - For the safety and accessibility of bicyclists: Protect bicyclists and delineate temporary bicycle routes by placing bicycle channelizing devices (BCD), or other approved devices, between the tem porary bicycle route and the W ork Area, as shown or as directed. Keep BCD in place, except as required for actual Work , until the permanent bicycle facility is completed and reopened, or bicycle traffic is returned to its original facility. When Work blocks the use of a bicycle route, and a temporary bicycle route detour is not practicable, install “Bicycles ON ROADWAY” (CW11 -1) signs in advance of the point where bicyclists must share a Traffic Lane with motor vehicle traffic. Locate the “Bicycles ON ROA DWAY” signs as shown or as directed. Provide traversable surfaces for temporary bicycle routes free of dirt, mud, G ravel or other Materials that could cause a bicyclist to slip and fall.
00220.03 Work Zone Notifications - Provide the following Work Zone notifications:
a.Over -Dimensional Vehicle Restrictions - When the P roject restricts the width, length, height, or weight of vehicles through a Work Zone or detours trucks around a W ork Zone, fill out and submit a completed copy of the "Highway Restriction Notice -Size and/or Weight" form (Form No. 734-2357), available from the ODOT Oregon Trucking Online website (see 00110.05(e)) , at least 35 Calendar Days before the restriction or detour takes effect.
b.Closures - Submit to the Engineer, in writing, for approval, all proposed closure schedules, as follows: • Lanes - A minimum of 7 Calendar Days before a lane closures begin. • Roads - A minimum of 14 Calendar Days before closure.
