GENERAL NOTES:

1. AMERICANS WITH DISABILITY ACCESS (ADA) DURING CONSTRUCTION

The needs and control of all road users (motorists, bicyclists, and pedestrians within the highway and/or public right-of-way, including persons with disabilities in accordance with the Americans with

Disabilities Act of 1990 (ADA), Title II, Paragraph 35.130) through a temporary traffic control “TTC” zone shall be an essential part of highway construction, utility work, maintenance operations, and the management of traffic incidents. The primary function of TTC is to provide for the reasonably safe and efficient movement of road users through or around TTC zones while reasonably protecting workers, responders to traffic incidents, and equipment.

Temporary facilities, including reasonably safe pedestrian routes around work sites, are also covered by the accessibility requirements of the Americans with Disabilities Act of 1990 (ADA) (Public Law

101-336, 104 Stat.327, July 26, 1990. 42 USC 12101-12213 (as amended)). Implementation of TTC plans and installation and maintenance of devices shall be the responsibility of the contractor performing the construction, alteration and/or maintenance of the highway or public right-of-way.

Temporary traffic control for pedestrians shall meet the accessibility requirements (Standards) set forth in Part 6 of the MUTCD. When an existing continuous sidewalk or street crossing route cannot be maintained for pedestrians because of construction, either temporary walkways with curb ramps are to be provided, or the construction shall be phased to maintain access to the affected addresses.

Contractors shall be allowed flexibility as long as the requirements are met.

The location of the construction project and whether or not accessible facilities are present shall also determine the extent of the needed temporary facilities. The contractor is only required to maintain practical continuity where accessible facilities already exist. On low speed rural roads that do not have sidewalks and are used by bicyclists, no additional measures are needed as the bicycles can share the available travel lanes with other traffic. On moderate to higher speed rural roads, if a bike lane exists then it should be properly detoured, complete with signage, to provide a safe route through or around the work area. If a road or bridge project affects vehicular traffic to a business, residence, school or any other type of pedestrian generating location with existing accessible facilities, then pedestrian and handicapped access must be maintained.

A continuous route for all pedestrians, including people with disabilities and bicyclists, shall be maintained at all times. When existing pedestrian facilities are disrupted, closed, or relocated in a

TTC zone, the temporary facilities shall be detectable and include accessibility features consistent with the features present in the existing pedestrian facility. The temporary route should enable pedestrians to bypass the construction site while minimizing the retracing of their steps or going significantly out of their way. Additional consideration must be given to people with disabilities since they may not have the physical or cognitive ability to improvise (e.g. balancing along the curb or a very narrow path) or use unofficial alternatives (e.g. using an adjacent grass surface). Temporary routes must meet the accessibility guidelines of the ADA for permanent facilities as well as the Public

Right-Of-Way Accessibility Guidelines (PROWAG) and shall be marked with the proper signage.

Should existing crosswalks at signalized intersections be closed or made inaccessible, temporary crosswalks should be painted in an accessible location. Temporary signals should include pedestrian phases.

Contractors shall not block temporary walkways with contractor parking, materials piles, signs, Project Number: Page 3 of 13 rubble or rubbish. Construction equipment and equipment operation must be separated from the temporary walkways. At work zones where higher volumes of pedestrian traffic or school children exist, pedestrian fences or other protective barriers may be needed to prevent access into the construction area.

Detour and diversion routes, when used for pedestrians and bicyclists, should be evaluated for the following items:

• Direct conflicts between pedestrians and vehicular traffic, work vehicles, and other work activities must be reduced with protective barriers or continuous high contrast fencing (min 36” high with a 6” high toe board). See MUTCD 6F.68 and 6D.02; PROWAG R303.

• Temporary pedestrian facilities should provide safe, accessible routes that replicate as nearly as practical the most desirable characteristics of the existing facility, and parallel the disrupted route whenever possible. A smooth, continuous hard surface should be provided throughout the entire length of the temporary pedestrian facility. There should be no curbs or abrupt changes in grade or terrain that could cause tripping or be a barrier to wheelchair use. The geometry and alignment of the facility should meet the applicable requirements of the

Americans with Disabilities Act Accessibility Guidelines (ADAAG) for Buildings and Facilities. See

MUTCD 6D.01 and 6D.02; PROWAG R303.3 and R302.6.

• Advance information placed at appropriate distances before the work zone allowing pedestrians to make timely decisions about routes through or around the work zone. See

MUTCD 6F.14; PROWAG 303.2.

• Transition information allowing pedestrians to find a safe path through and around work zones, which is critical when the pathway is restricted, diverted or detoured. See MUTCD 6F.14;

PROWAG R303.2.

• Work area information assisting in safe passage of pedestrians through the work zone. This information is needed on all pedestrian routes except detours. See MUTCD 6F.14

• Exit information directing pedestrians back to the original route. See MUTCD 6F.14

• Crosswalk placement at intersections may need additional signage, temporary striping, traffic signal modification, pedestrian signals with audible alarms if justified, proper push button height, and ramps. See MUTCD 6H.29, 6F.80, and 4E.06; PROWAG R303.5 and R304.

• Accommodations for other transit forms (busses, trains etc.) are made. See MUTCD 6D.02

• Requirements of the ADAAG, PROWAG, and MUTCD are adhered to.

• Access is maintained to the affected businesses and residences.

Description: This work shall consist of preparation and implementation of a Pedestrian Temporary

Traffic Control (TTC) Plan as needed in the construction area inclusive to provide temporary facilities, including reasonably safe pedestrian routes around the Contractor’s work in accordance with the

Americans with Disabilities Act (ADA).

Materials: All materials (signs, barricades, temporary facilities and appurtenances) shall be in accordance with the Americans with Disabilities Act of 1990 (ADA), the Public Right-Of-Way

Accessibility Guidelines (PROWAG), and Manual on Uniform Traffic Control Devices (MUTCD).

Workmanship: The Contractor shall develop a Pedestrian TTC Plan for work at the construction site based upon his planned construction operation. The Contractor shall submit a written outline of the

TTC plan along with a layout of all temporary facilities, barricades and signing for review and approval prior to construction. The TTC plan shall provide the following:

1. The needs and control of pedestrians and bicyclists within the roadway and/or public right-of-way, including persons with disabilities in accordance with the Americans with Disabilities Act of 1990

(ADA), Title II, Paragraph 35.130) through a temporary traffic control “TTC” zone shall be an essential part of highway construction, utility work, maintenance operations, and the management of traffic incidents. The primary function of TTC is to provide for the reasonably safe and efficient movement of road users through or around TTC zones while reasonably protecting workers, responders to traffic incidents, and equipment.

2. Temporary facilities, including reasonably safe pedestrian routes around work sites, are also covered by the accessibility requirements of the Americans with Disabilities Act of 1990 (ADA) (Public Law

101-336, 104 Stat.327, July 26, 1990. 42 USC 12101-12213 (as amended)). Implementation of TTC plans and installation and maintenance of devices shall be the responsibility of the Contractor performing the construction, alteration and/or maintenance of the roadway or public right-of-way.

When an existing continuous sidewalk or street crossing route cannot be maintained for pedestrians because of construction, either temporary walkways with curb ramps are to be provided, or the construction shall be phased to maintain access to the affected addresses.

3. The location of the construction project and whether or not accessible facilities are present shall also determine the extent of the needed temporary facilities. The Contractor is only required to maintain

Project Number: Page 12 of 13 practical continuity where accessible facilities already exist. On low speed rural roads that do not have sidewalks and are used by bicyclists, no additional measures are needed as the bicycles can share the available travel lanes with other traffic. On moderate to higher speed rural roads, if a bike lane exists then it should be properly detoured, complete with signage, to provide a safe route through or around the work area. If a road or bridge project affects vehicular traffic to a business, residence, school or any other type of pedestrian generating location with existing accessible facilities, then pedestrian and handicapped access must be maintained.

4. A continuous route for all pedestrians, including people with disabilities and bicyclists, shall be maintained at all times. When existing pedestrian facilities are disrupted, closed, or relocated in a

TTC zone, the temporary facilities shall be detectable and include accessibility features consistent with the features present in the existing pedestrian facility. The temporary route should enable pedestrians to bypass the construction site while minimizing the retracing of their steps or going significantly out of their way. Additional consideration must be given to people with disabilities since they may not have the physical or cognitive ability to improvise (e.g. balancing along the curb or a very narrow path) or use unofficial alternatives (e.g. using an adjacent grass surface). Temporary routes must meet the accessibility guidelines of the ADA for permanent facilities as well as PROWAG and shall be marked with the proper signage. Should existing crosswalks at signalized intersections be closed or made inaccessible, temporary crosswalks should be painted in an accessible location.

Temporary signals should include pedestrian phases.

5. Contractors shall not block temporary walkways with Contractor parking, materials piles, signs, rubble or rubbish. Construction equipment and equipment operation must be separated from the temporary walkways. At work zones where higher volumes of pedestrian traffic or school children exist, pedestrian fences or other protective barriers may be needed to prevent access into the construction area.

6. Detour and diversion routes, when used for pedestrians and bicyclists, should be evaluated for the following items:

• Direct conflicts between pedestrians and vehicular traffic, work vehicles, and other work activities must be reduced with protective barriers or continuous high contrast fencing (min 36” high with a 6” high toe board). See Manual on Uniform Traffic Control Devices (MUTCD) 6F.68 and 6D.02; PROWAG R303.

• Temporary pedestrian facilities should provide safe, accessible routes that replicate as nearly as practical the most desirable characteristics of the existing facility, and parallel the disrupted route whenever possible. A smooth, continuous hard surface should be provided throughout the entire length of the temporary pedestrian facility. There should be no curbs or abrupt changes in grade or terrain that could cause tripping or be a barrier to wheelchair use. The geometry and alignment of the facility should meet the applicable requirements of the Americans with

Disabilities Act Accessibility Guidelines (ADAAG) for Buildings and Facilities. See MUTCD 6D.01 and 6D.02; PROWAG R303.3 and R302.6.

• Advance information placed at appropriate distances before the work zone allowing pedestrians to make timely decisions about routes through or around the work zone. See MUTCD 6F.14;

PROWAG R303.2.

• Transition information allowing pedestrians to find a safe path through and around work zones, which is critical when the pathway is restricted, diverted or detoured. See MUTCD 6F.14;

PROWAG R303.2.

• Work area information assisting in safe passage of pedestrians through the work zone. This information is needed on all pedestrian routes except detours. See MUTCD 6F.14

• Exit information directing pedestrians back to the original route. See MUTCD 6F.14

Project Number: Page 13 of 13

• Crosswalk placement at intersections may need additional signage, temporary striping, traffic signal modification, pedestrian signals with audible alarms if justified, proper push button height, and ramps. See MUTCD 6H.29, 6F.80, and 4E.06; PROWAG R303.5 and R304.

• Accommodations for other transit forms (busses, trains etc.) are made. See MUTCD 6D.02

• Requirements of the ADAAG, PROWAG, and MUTCD are adhered to.

• Access is maintained to the affected businesses and residences.

• Frequent checks of the pedestrian and bicycle accommodations are made during construction to ensure that the temporary traffic control plan is followed, traffic control devices are maintained in good condition, and safe, accessible pedestrian and bicycle routes are available at all times.

Upon approval the Contractor shall implement the prepared TTC plan. The Contractor shall be responsible for all work associated with the TTC plan including all initial placement, maintenance, relocations, and removal of all signs, barriers and temporary facilities.

Measurement and Payment: Traffic control devices used for the pedestrian or bicycle detour will be paid under their respective bid items when applicable. Relocation of each device to another location shall be paid under Traffic Control Maintenance. This item includes all design, submit, modify, inspect, and manage the Pedestrian Temporary Traffic Control Plan. Additional materials, labor, and equipment needed to complete and maintain the approved pedestrian detour will be measured and paid for by Force Account.
