0 Chapter 6: Intermodal Integration/ Airport Access Airports are part of a larger transportation network that provide transportation into, out of, and within Tennessee. Especially in northeast and west Tennessee, airports often provide needed access to rural communities, and in more urban parts of the state such as Nashville, Memphis, Chattanooga, and Knoxville, airports are a hub around which residents and visitors alike can access business and recreation. Airports are often a visitor’s first access to Tennessee before accessing the other transportation networks within the state. In addition to the 78 system airports in Tennessee, there are 1: Over 28,413 miles of functionally classified roads 20,087 bridges on public roads within Tennessee 26 public transit systems supporting over 32 million trips by public transportation (estimated in 2012) 949 miles of navigable waterways, 887 miles of which are on the Tennessee, Cumberland, and Mississippi Rivers Over 1,200 miles of Class I railroad tracks owned and operated by six railroad companies and 21 short line railroads When discussing intermodal access, it’s important to recognize that transportation networks often rely on one another. Many users drive or take the bus to an airport, and in turn walk or bike to a bus stop. Each of these transportation resources relies on other modes to ensure their operational success. This section discusses how airports are integrated with other transportation modes in Tennessee and the importance of continued intermodal integration. Airport Roadway Connections To access the state’s aviation system from the ground, residents and visitors primarily utilize Tennessee’s extensive network of roadways. Tennessee’s location within the U.S., including being surrounded by eight states, make it a major thoroughfare for interstate travel. Roadways include interstates, United States (U.S.) highways, state routes, county roads, and city roads. There are 15 interstates in Tennessee including: I-40: Runs east-west across the state from the Tennessee/North Carolina border to Memphis in the southwest corner of the state. At 455 miles, it is the longest interstate portion in Tennessee. I-24: Spans 180 miles through the center of the state. This interstate originates at the Kentucky state line and runs north and south, terminating in Chattanooga. I-65: Runs north-south from Kentucky to Alabama and passes through Nashville near the center of the state. I-75: Runs north-south through the eastern portion of the state from Kentucky to Georgia, terminating near Chattanooga. 1 TDOT 25-Year Long Range Transportation Policy Plan; https://www.tn.gov/content/dam/tn/tdot/documents/Travel_Trends_022316.pdf 1 I-55: Starts at the southwest corner in the state at the Mississippi border and runs northwest to the Arkansas border. The majority of I-55 runs through Arkansas but also serves the Memphis metro area. I-81: Starts at Dandridge, Tennessee and terminates at the Virginia state border at the northeastern edge of the state. I-26: Located in the northeastern corner of the state, this interstate originates in Kingsport and ends at the North Carolina state line. I-155: Provides western connectivity from Dyersburg, Tennessee to I-55 in Missouri. I-840 and I-440: Both provide additional connectivity around the Nashville metro area. I-269 and I-240: Both provide additional connectivity around the Memphis metro area. I-640, I-140, and I-275: They provide additional connectivity around the Knoxville metro area. There are also 46 U.S. highways and 445 state routes. The longest U.S. highway in Tennessee is US-70, which traverses the state east-west and is 478 miles long. The longest state route (SR) is SR-1, which is 538 miles long, begins in Memphis, and terminates in Bristol. Figure 1 depicts the major interstates in Tennessee. The state road network provides the ability for much of the state population to conveniently access Tennessee system airports. A summary of the roadway connectivity analysis for each system airport is provided in Table 1. Airport connectivity to adjacent roadway linkages was determined through online resources including Google Earth and Google Maps. The table presents the following information: The distance to the nearest downtown from the airport. If the population of the nearest city or town is less than 10,000, the distance to the closest city or town with 10,000 or more people is also provided. The road(s) that provide direct access to each airport. Direct access is defined by the airport being located on a major highway or road or connected via an airport access road. The driving distance to the closest interstate, U.S. highway, or state highway via indirect access. 2 Figure 1: Tennessee Highway System Source: ArcGIS Evaluation, Kimley-Horn 2020 3 Table 1: Tennessee Airport Roadway Connectivity Direct Access Roadways Nearest Indirect Access Roadways (no. of lanes) Downtown State FAA Inter- U.S. Major No. of Miles from City/ Miles from Associated City Airport Road/ ID state Hwy Roadway Lanes Airport Town Airport Highway SR-39 2 2 McMinn County SR-30 Athens MMI None None US-411 4 4 Athens 4 Airport (4L) I-75 4 9 SR-30 2 1.5 Benton 5 US-411 SR-33 Benton Chilhowee Gliderport 92A None Cleveland 20 (4L) (4L) I-75 4 20 Athens 20 William L Whitehurst SR-18 US-64 4 3 Bolivar 4 Bolivar M08 None None Field (2L) I-40 4 28 Jackson 31 I-81 4 2 Kingsport 14 Bristol/ Johnson/ SR-357 Tri-Cities Airport TRI None None I-26 4 7 Johnson 15 Kingsport (4L) US-23 4 7 Bristol 17 SR-69 2 1 Camden 4 Benton County US-641 2 1 Camden 0M4 None None None Airport US-70 2 2 Jackson 60 I-40 4 13 SR-100 2 1 Centerville 5 Centerville Municipal SR-48/230 Centerville GHM None None I-40 4 13 Airport (2L) US-412 4 22 Columbia 30 SR-319 4 0.5 Hixson 6 Chattanooga Dallas Bay Sky Park 1A0 None None None US-27 4 4 I-75 8 18 Chattanooga 18 US-64 SR-153 Chattanooga Lovell Field CHA None I-75 8 1 Chattanooga 7 (4L) (6L) ALT SR-12 Clarksville Outlaw Field CKV None US-41 I-24 4 5 Clarksville 8 (7L) (7L) SR-2 2 3 Cleveland Regional Cleveland RZR None None None US-11 2 3 Cleveland 7 Jetport I-75 4 6 4 Table 1: Tennessee Airport Roadway Connectivity Direct Access Roadways Nearest Indirect Access Roadways (no. of lanes) Downtown State FAA Inter- U.S. Major No. of Miles from City/ Miles from Associated City Airport Road/ ID state Hwy Roadway Lanes Airport Town Airport Highway US-641 2 2.5 Clifton 2 SR-128 Clifton Hassell Field M29 None None US-64 4 4 (2L) I-40 4 41 Jackson 60 SR-321 2 3 Collegedale 2.5 Collegedale SR-317 Collegedale FGU None None US-64 4 4 Municipal Airport (2L) I-75 4 6 Chattanooga 19 SR-243 SR-50 4 7 Mt.
