1.2. TERMINOLOGY

Project Information Plan (PIP) ‐ Defines the methods to be used to communicate with affected audiences about the construction project, expected work zone impacts, and changing conditions.

Temporary Traffic Control Plan (TTCP) ‐ One of the contract documents that addresses the traffic safety and control through the work zone. The TTCP will follow Federal and DDOT Standards and Guidelines for the layout and placement of traffic control devices, signs, and related project equipment.

Traffic Safety Supervisor ‐ Point of contact during construction. The Traffic Safety Supervisor will ensure full implementation of the Transportation Management Plan (TMP) to ensure minimal disruption to the traveling public. The Traffic Safety Supervisor will also ensure that project activities conform to the TMP and that contingency plans are implemented, if necessary.

Transportation Management Plan (TMP) ‐ Presents a set of transportation management strategies and describes how each strategy will be applied to address the work zone impact of a roadway object.

Transportation Operations (TO) Strategies ‐ Transportation operations component of the TMP that addresses sustained operations and management of the work zone impact area. This may (or may not) include travel demand management, signal timing changes, ITS, safety, and enforcement strategies.

Work Zone ‐ Area of a roadway with construction, maintenance, or utility work activities, typically marked by signs, channelizing devices, barriers, pavement markings, and work vehicles. The work zone extends from the first warning sign, typically a ROAD WORK AHEAD sign, to the END ROAD WORK sign or last temporary traffic control device.

Work Zone Impacts ‐ Any deviation from the normal expected range of transportation safety and mobility resulting from the presence of a work zone. Extent of impacts may vary depending on characteristics of location, roadway, and project scope.

2. INTRODUCTION

The CIA Bridge Overpass is located in the George Washington Memorial Parking (GWMP) in Northern

Virginia. This park road is owned and maintained by the National Park Service. In order to preserve the safety and integrity of the bridge, it is required to rehabilitate the bridge; as well as, mill and overlay the

Southwest Ramp, CIA Entrance and minimal drainage repairs. A one lane closure on GWMP will be necessary to complete all the work below the CIA Bridge. Construction will be performed in 4 stages in order to facilitate the reconstruction work. No detour will be necessary.

2.1. TEMPORARY TRAFFIC CONTROL PLAN (TTCP)

The Temporary Traffic Control Plan (TTCP) includes a detailed sequence of construction, general notes, and special details for implementing the construction stages. This plan requires that all traffic control devices and maintenance of traffic plans comply with the latest edition of The Manual on Uniform

Traffic Control Devices (MUTCD) and FLH FP‐14 Standard Specifications for Construction of Roads and

Bridges on Federal Highway Projects. It is anticipated that the project will adhere to these plans for maintaining traffic during construction. Any proposed deviation from the plans should be submitted to

FLH Contracting Officer (CO) for review and approval. This TMP shall be amended and approved for any major changes, as necessary.

The Contractor shall coordinate the TTCP with nearby projects. This two‐way coordination serves in the best interest of the traveling public.

2.2. MAINTENANCE OF TRAFFIC (MOT)

The roadway construction will result in some interruptions to traffic flow along the roadway facility;

consequently travel time through the corridor may increase during the construction stages. The goal of this project is to limit the impact during the peak travel times in the area. While the traveling public and surrounding community can expect slight or minor inconvenience during construction, the proposed

TTCP minimizes disruptions by limiting lane closures along GWMP to non‐rush hours.

4. PROJECT DESCRIPTION

George Washington Memorial Parkway currently serves as a park road that also provides access to and from the south banks of the Potomac River and to the northwest of Langley, VA. A lane closure on a 0.17 miles segment of the parkway will be performed to be able to repair the bridge piers, beams and abutments during non‐peak hour traffic (See Figure 1). The current configuration along the corridor is a four lane divided roadway, two on each direction. As a result, traffic patterns on each direction will be affected by the lane closures.

Figure 1. Project Area

4.1. PROJECT INFLUENCE AREA

The construction along the corridor is expected to be divided into 4 stages and each stages will consists on a single lane closure for reconstruction.

6. DESIGN OF TEMPORARY TRAFFIC CONTROL PLANS (TTCPs) The TTCPs have been produced by EFLHD, based on the latest edition of the MUTCD.

6.1. SIGNING DURING CONSTRUCTION

This section details the installation, maintenance, and removal of temporary signing specifically related to construction, which is generally removed when the work is completed.

6.1.1. Installation of Temporary Signs

Temporary signing shall be the primary method of communicating drivers of shifted lanes ahead. These signs shall contain a clear, concise message and be placed to provide maximum visibility for drivers to read, interpret, and react to their messages. The following items shall be used for the project:

Work on the project shall not commence until all necessary construction signs, as proposed in the TTCP, are in place.

8 | P a g e

Signs and devices shall be installed according to the location and spacing shown in the TTCP whenever possible.

For short term closures, as applicable, signs shall be placed in such positions to allow motorists the opportunity to reduce their speed prior to the work area. Signs will be installed on the same side of the roadway as the work area.

For short term closures, as applicable, signs shall be installed beginning with the advanced warning signs and proceeding forward toward the work area. Signs will be removed in the reverse order, beginning at the work area, or end of the traffic control pattern, and proceeding back toward the advanced warning signs.

For short term closures, as applicable, when signs require frequent moves, portable signs mounted on weighted stands may be used. Portable signs shall be placed such that the face of the sign is fully visible to oncoming traffic and the stands will be securely weighted and erected to guard against being blown over by prevailing winds or gusts from passing vehicles.

Non‐portable signs are prohibited on this project.

Portable Dynamic Message signs shall be used to convey upcoming and/or current construction information.

For additional information and guidance relating to the placement of temporary signs refer to the

MUTCD, Plans, and the Special Contract Requirements.

6.1.2. Maintenance and Removal of Signs

Maintain all construction signs in accordance with Subsection 635.07 of the Special Contract

Requirements. Defaced, damaged, or dirty construction signs shall be replaced, repaired, or cleaned without delay. Prior to installing signs, any conflicting existing signs shall be covered with an opaque material. Once the temporary traffic pattern is removed, the existing signs shall be uncovered. Signs not in effect shall be covered or removed when no longer necessary. Signs will be inspected and documented on a daily basis.

6.1.3. Modifications to Temporary Signing

In the case of potential danger to the traveling public or other circumstances where the signing is inadequate, changes to the TTCP shall be considered to remedy the situation. These changes may involve the use of different types and/or sizes of signs, modifying the number or locations of signs, and any other modifications or additions required to protect the safety of the traveling public. In such cases, adjustments to the TTCPs to improve the visibility of the signs and devices and to better control traffic operations will be made only at the direction of the Traffic Safety Supervisor with approval by the CO.

6.2. PERMANENT SIGNING

Permanent signing will conform to the MUTCD and will be shown on separate signing plans. The permanent signing will be installed toward the end of each stage before each roadway segment is re‐ opened to traffic. These signs will be covered until they are needed.

6.3. MOT TYPICAL APPLICATIONS FOR ROAD CLOSURES

This TMP does not include the MOT typical applications. The contractor shall conform to the latest version of the MUTCD and the EFL Standard and Detail Drawings for typical MOT applications. The

9 | P a g e applications for lane closures and work along the roadway under construction shall be applied where necessary.

7. WORK ZONE IMPACTS ASSESSMENT

The bridge rehabilitation project will consist of lane closure of segments of GWMP and will affect traffic that typically utilizes the roadway.

7.1.1. Motorist Information Strategies

Prior to and during the construction stages, appropriate GWMP temporary traffic control information should be provided by NPS to the public via Public Service Announcements (PSA), media news releases, Web Sites, flyers, brochures, meetings, letters/postcards, purchased advertisements, and through other information materials by National Park, and other appropriate agencies and organizations.

7.1.2. Safety

Safety should be placed as a top priority during times when construction impacts to traffic cannot be avoided. Every measure will be taken to reduce crash potential by adjusting the temporary traffic control and traffic operations to ensure the safety of the traveling public, residents, and workers. The

Traffic Safety Supervisor should monitor crash data in the work zone and make appropriate changes in the temporary traffic control and operations as necessary.

8. CONSTRUCTION IMPACTS ON COMMUNITY

This section identifies all direct traffic impacts on the community that will have a disruptive effect and provide corrective measures, where feasible, to reduce the extent of community disruption.

8.1. Local Community

There will be an increase in traffic to the area, including heavy vehicles and machinery, during construction. As identified in the Project Information Plan (PIP), the local news media and local community organizations will be notified in advance of any road closings, planned detours, and other construction related activities that could excessively inconvenience the community so that motorists, residents, and business persons can plan travel routes in advance.

8.3. Mitigation Measures

Every effort will be made to keep the community apprised of the construction progress and pending activities through the measures outlined in the PIP. By communicating the project’s status and upcoming project activities during the construction process will be better able to plan for the temporary impacts associated with the lane closures.

9. PROJECT INFORMATION PLAN (PIP)

The contractor shall support EFLHD and NPS as necessary to maintain open and continuous lines of communication with the traveling public, and the surrounding community through the use of media, 10 | P a g e

Web site updates, and other means. The PIP contains the standard operating procedures for notifying the public of maintenance of traffic issues.

The Public Information Plan (PIP) plan uses a combination of helpful tips, approaches, and processes that have proved effective on other projects. It will be administered through the NPS and will follow their policies and procedures.

10. TMP IMPLEMENTATION

The contractor shall work with EFLHD and NPS to implement elements of the TMP, such as public information and outreach efforts prior to construction. The contractor shall have the Traffic Safety Supervisor, an onsite trained work zone specialist responsible for efficiently and appropriately implementing the TMP elements. The Traffic Safety Supervisor shall be responsible for reviewing all operations throughout the project limits on a regular basis, including the condition of all traffic control devices.

10.1. TMP MODIFICATION

The TMP is intended to be a living document and will be updated periodically throughout the duration of the project. Revisions to the TMP are made as the MOT/Design plans are updated. The revised/alternative TMPs are approved by the Traffic Safety Supervisor and CO. The final document has a section dedicated to major TMP element revisions. The Contractor shall be responsible for updating the TMP with approval by EFL.
