The process is implemented by conducting 2-day workshops for State departments of transporta- tion (DOTs). The American Association of State Highway and Transportation Officials (AASHTO) and the Federal Highway Administration (FHWA) jointly fund ACTT workshops. In May 2004, the Oklahoma Department of Transportation (ODOT) hosted a workshop that applied ACTT principles to its Crosstown project, which will realign I-40 running along the southern edge of Downtown Oklahoma City and points further south. accepted The $400 million project will replace this primarily elevated section of I-40 on offset alignment to the south. A large section of the new facility will be depressed. The existing facility was built inor the 1960s, andpractice. designed for an ultimate traffic volume of 76,000 average daily traffic (ADT). Today's ADT exceeds 110,000 over this section, which passes over 250 fracture critical members of the longest twin bridge structures in the State. Additionally, 90 percent of this section of I-40 is rated as a critically-high crash facility. The existing facilityor will be removed at the completion of the mainline construction and a six-lane at-grade boulevard will be constructed on the existing alignment for local traffic. Key project challenges include: • Complete and open the mainline to traffic by Septembercurrent 2008. • The existing railroad corridor must be realigned five blocks south of its current location. Rail operations in the corridorArchival must continue uninterrupted both during and after construction. • A six-lane boulevard must be constructed to replace the existing stretch of I-40. • The project calls for a 112 km/h (70 mi/h) designguidance speed. • A direct connection must be established to Bricktown and downtown. • Methods must minimize disruptionreflect to downtown and Bricktown traffic during construction. The workshop was held on May 25-27, 2004, in Oklahoma City, Oklahoma, and brought together 75 transporta- tion professionals from across the nation. The primary objective of the workshop was to draw on the expertise of participants to help ODOT achievepolicy, its primary goal of opening the mainline to traffic by September 2008. Gary Ridley, ODOTlonger Director, expressed support for the workshop as he welcomed the participants. During the opening session Shirley Ybarra, Transportation Research Board (TRB) A5T60 task force member and former Virginiano Department of Transportation (VDOT) Secretary of Transportation, gave the keynote address on "Why ACTT? Why Now?" Following the opening remarks, a project overview by the project management team and a bus tour of the project concluded the opening day. Over the course of the workshop, participants broke into skill set teams to examine how the ACTT concept Maycould be implemented to accelerate various aspects of the project. The skill sets selected by ODOT prior to the regulation,start of the workshop were: Railroad/Utilities; Structures/Geotechnical; Innovative Contracting/Financing; Long Life Pavement/Maintenance; Traffic/ITS/Safety/Public Relations; Environmental; Construction/Materials; and Roadway Design/Geometrics. Each skill set team focused on how the ACTT process applied to the specific ACTT Workshop | 1 accepted or practice. concerns of their area of expertise, while collectively the teams searched for methods/measures to help ODOT achieve its goals of maintaining traffic with minimal disruption; accommodating local/regional/ national/international events; providing access to emergency facilities; opening I-40 to traffic by September or 15, 2008; constructing the facility within budget; and maintaining a safe work zone. Workshop participants remained focused throughout the workshop and made numerous recommendations, many of which were deemed viable and will be pursued, according to ODOT. As the host agency, ODOT will current examine the recommendations and determine which will be implemented on its Crosstown Project. With the workshop completed, it now remains for ODOT to sift through the various ideas/recommendations and decide which ideas should be implemented in future planning, design, and construction phases of the Archival "I-40 Crosstown Expressway Relocation." guidance reflect policy, longer no May regulation, 2 | Oklahoma accepted or practice. or current Archival guidance reflect CHAPTER 1 policy, longer no ACTT Goals and Objectives May regulation, ACTT Workshop | 3 Highway construction continues to produce significant disruptions in communities across the Nation as Departments of Transportation (DOTs) work to update an aging infrastructure system. While highway con- struction is unavoidable, excessive construction time is unnecessary and often can be dangerous. It is costly, prolongs workers' exposure to traffic, and subjects travelers to substandard conditions. The Accelerated Construction Technology Transfer (ACTT) initiative aims to minimize travel delays and community disruptions by reducing cost and construction time and improving quality, traffic control, and safety. 1.1 BACKGROUND ACTT is a process that encourages the use of innovative technologies and methods to accelerate the construc- tion of major highway projects to reduce user delay and community disruption. A complete accelerated construction approach involves evaluating the planning, design, and construction activities within a highway corridor using multiple strategies and technologies. Successful ACTT deployment requires the thorough examination of all facets of a highway corridor with the objective of improving safety and optimizing cost effectiveness while minimizing adverse

    Southwestern Region United States Department of Agriculture RG-3-07-07 Forest Service July 2013 Historic Route 66 Auto Tour — Williams to Flagstaff, Arizona Williams Ranger District Kaibab National Forest Points of Interest Take a trip back in time, to a day when driving across America meant finding adventure and freedom on the open road. Imagine what it was like when Arizona’s first tourists saw scenic wonders like the Navajo Indian Reservation, Petrified Forest, Grand Canyon National Park, and pine-laden Kaibab National Forest. Cruise down memory lane and discover the past on Historic Route 66. Williams served travelers on Route 66 as part of the “Main Street of America.” Now called Bill Williams Avenue in this picturesque western town, the historic road is still lined with businesses dating from the highway’s heyday. In 1984, Williams became the last Route 66 town in America to be bypassed by Interstate 40. The tour winds through beautiful scenery toward Bill Williams Mountain. Interstate 40 now covers this section of Route 66 at Davenport Lake. Pittman Valley was first settled by ranchers in the 1870s. Tourists found guest cabins and a gas station along the road here. Historic Route 66 Auto Tour ― Williams to Flagstaff, AZ 1 Garland Prairie Vista has a beautiful view of the San Francisco Peaks, the highest mountains in Arizona. A favorite with photographers, this view appeared on many Route 66 postcards. Parks is a small community that started out as a railroad stop in the 1880s and later became a wayside for highway tourists. When the highway was thriving, the area had a Forest Service campground, several motels, gas stations, curio shops, and a road that led north to the Grand Canyon.

  • Transportation Improvement Corridors in This Plan Utilized the Following Method
    CHAPTER 7: TRANSPORTATION CORRIDORS 7.0 DEFINITIONS Three types of transportation corridors are identified in the 2005-2030 Oklahoma Statewide Intermodal Transportation Plan: • Transportation Improvement Corridors: These are highway corridors where projected traffic volumes indicate additional capacity will be needed by 2030. • National High Priority Corridors: These are Congressionally-identified corridors of national significance. There are four such corridors in Oklahoma: (1) US 287 [Ports-to-Plains Corridor] from Texas to Colorado in Cimarron County; (2) US 54 [TransAmerica Corridor] from Texas to Kansas in Texas County; (3) I-35 from Texas to Kansas; and, (4) US 412 from Tulsa to Memphis, Tennessee. These corridors are eligible for special discretionary funding from the National Corridor Planning and Development (NCPD) program. • Freight Operational Improvement Corridor: These corridors represent highways with high truck traffic but do not indicate capacity needs by 2030. However, the efficiency of the these corridors is compromised by conditions such as stops in towns and cities, bridge deficiencies, geometrics, urban speed zones, school zones, at grade rail crossings, or other operating conditions that reduce the efficiency of freight movements. These corridors can benefit from corridor studies and improvements from a menu of improvements such as bypasses; intelligent transportation systems for driver information on traffic flows, weather conditions, etc.; bridge upgrades; rail grade separations; signal timing; and, geometric roadway improvements. 7.1 TRANSPORTATION IMPROVEMENT CORRIDORS 7.1.1 Definition The Transportation Improvement Corridors are highway corridors needing capacity upgrades by 2030. Transportation Improvement Corridors were first identified in the 1995 Oklahoma Statewide Intermodal Transportation Plan and resulted in the policy “To provide for continued safe and efficient movement, the plan includes the development from two to four lanes along the corridors”.
