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”. The 2005 – 2025 Statewide Intermodal Transportation Plan continued this policy. This policy is continued in this version of the plan with additional consideration of upgrading four-lane facilities to six-lane facilities or to obtain right-of-way for the ultimate Corridor configuration. Delineation of Transportation Improvement Corridors in this plan utilized the following method: • Files of current traffic volumes (2003) by highway control section were used along with historical traffic growth factors to calculate future traffic volumes (2030). 177 • Level-of-Service (LOS) C capacities were determined for each existing highway (2 lane, 4 lane, 4 lane divided) by terrain type (level, rolling, or mountainous) for each highway control section. • Calculated 2030 volumes were compared to the LOS C capacities for each existing highway control section. This resulted in a volume-to-capacity (v/c) ratio. • LOS C has a v/c ratio of 1 and results in a satisfactory LOS. Highway sections exceeding LOS C (greater than 1.0) were considered as candidates for Transportation Improvement Corridors. • Final delineation of corridors also considered the following factors: o judgment that congestion is resulting from a genuine capacity problem that would require more lanes rather than a capacity problem that could be alleviated by reconstruction and improvement of existing lanes with better geometrics and traffic handling characteristics. o judgment for logical termini: corridors defined with lengths that could demonstrate independent utility, not result in a mixture of highway segments with differing lanes and transition points; connect from highway junction to highway junction or city to city. Thus, some non-congested segments are included in defined corridors. o judgment on constructability: some congested areas are scenic highways or have some other factor that would preclude addition of capacity. o judgment that some capacity problems could be alleviated with “spot” or localized capacity additions and definition of a corridor was not needed. 7.1.2 2005-2030 Transportation Improvement Corridors Seventeen corridors have been identified as Transportation Improvement Corridors based on the above process. These Corridors may coincide with National High Priority Corridors (such as I-35) but generally are separate. When they coincide, description and analysis is contained under ANational High Priority Corridors@. Most of the corridors selected are projected to be four-lane highway facilities; however some facilities, such as I-40 or I-35 may need six or more lanes to adequately handle projected traffic. The State Transportation Improvement Corridors for the 2005 - 2030 Oklahoma Statewide Intermodal Transportation Plan, totaling 17 and shown in Figure 7.1 are the following: 1. US 270 / SH 3 from the junction with SH 34 in Woodward, Woodward County southeast to Watonga, Blaine County and continuing southeast on US 281 and US 281 Spur to the junction with Interstate 40 in Canadian County, a total of 95 miles. 2.

Summary statistics for the Transportation Improvement Corridors are the following: $ Total Estimated Cost for all Transportation Improvement Corridors: $2,304,620,000 $ Historical funding and project funding contained in the FFY 2005 - FFY 2012 Construction Work Plan have provided and will provide approximately 38% of Transportation Improvement Corridor estimated construction needs. $ Historical funding and Construction Work Plan funding has generally scheduled the highest cost projects in the Corridors first and generally in urban and/or high average daily traffic locations. 7.1.4 Transportation Improvement Corridor Mileage $ Total Transportation Improvement Corridor Mileage: 829 miles $ Historical funding and Construction Work Plan funding has completed and will complete, respectively, approximately 40 per cent of total Corridor mileage. 7. 2 NATIONAL HIGH PRIORITY CORRIDORS 7.2.1 Definition Congress has specified some 45 routes on the National Highway System (NHS) as AHigh Priority Corridors@. These designations were made on the importance of the route in serving regional, national, and international freight and vehicle movements. Designation of these routes began with the ISTEA transportation bill from 1992 to 1997 and continued with the TEA-21 transportation bill. The significance of designation as a NHS High Priority Corridor is that it allows National Corridor Planning and Development Funds, a discretionary fund administered by the U.S. Secretary of Transportation in cooperation with Congress, to be spent to plan, construct, or maintain these corridors. The Corridors can also ultimately be designated Interstate routes if built to Interstate standards. Designation and improvements may prove useful in economic development and safety improvements for the movement of freight and other vehicles. 180 7.2.2 Oklahoma=s NHS High Priority Corridors Oklahoma has four routes designated as NHS High Priority Corridors. These corridors locations are the following and are depicted on the NHS High Priority Corridor Map in Figure 7.1: NHS High Priority Corridor #3: The East-West Transamerica Corridor which extends from the Atlantic Coast in the Hampton Roads area in Virginia extending westward to California across West Virginia, Kentucky, Illinois, Missouri, Arkansas, Kansas, Oklahoma, Texas, Colorado, New Mexico, Utah, Arizona, Nevada, and California. In Oklahoma, US 54 in Texas County from the Kansas Stateline southwest to the Texas Stateline is included.
