14th Amendment Highway

 
 

14th Amendment Highway

The 14th Amendment Highway study was conducted by a team of consultants led by Cambridge Systematics, Inc. for the Federal Highway Administration (FHWA), and was submitted to Congress pursuant to Section 1927 of the federal transportation authorization legislation known as SAFETEA-LU. This study is one of two companion studies authorized by SAFETEA-LU legislation. The studies focused on highway corridors originating in Georgia, and include the 14th Amendment Highway and the 3rd Infantry Division Highway.

The 14th Amendment Highway was proposed to extend from Augusta, Georgia to Natchez, Mississippi, servicing intermediate cities of Macon and Columbus, Georgia, and Montgomery, Alabama. A portion of the highway corridor in Georgia was designated as a Congressional High Priority Corridor (HPC-6) under Section 1105 (c) of the Intermodal Surface Transportation and Efficiency Act (ISTEA) of 1991. The segment from Columbus to Macon was previously studied by the Georgia Department of Transportation (GDOT) as part of the Governor's Roadway Improvement Program (GRIP).

The first stage of this study focused on preliminary data collection, identification of potential highway segments, alternative alignments and conceptual engineering designs for each segment, estimates of construction costs, and recommendations for additional planning studies to be conducted in an optional phase II as directed by FHWA.

Project work focused on data collection, initial outreach activities, and definition of project control points in each of the key service and terminus cities. Engineering design work took place in the fall of 2010, and was followed by cost estimation work, and recommendations for further planning studies in the spring of 2011. The project was completed in June, 2011 and its findings were submitted to Congress.

Gulf Coast Strategic Highway

The I-14 Central Texas Corridor, authorized in 2015, runs from West Texas to the Texas-Louisiana border generally following US 190. The first 25-mile section of I-14 from Killeen and Fort Hood to I-35 at Belton was added to the Interstate Highway System in 2017.

The Central Texas Corridor may be expanded to the west to San Angelo, Goodfellow Air Force Base. The I-14 North branch may extend to Midland-Odessa to Interstate 20. The I-14 South branch runs westward to join I-10. Including Fort Bliss, I-14 links six military facilities across three states.

Spur routes in Texas would extend southward to provide better access to the strategic military seaports at Beaumont, Port Arthur and Corpus Christi. This will enhance military readiness and efficiency as envisioned by President Dwight D. Eisenhower when he first commissioned America’s interstate highway system in 1956. The Permian Basin Spur would follow US 385 from I-20 at Odessa south to I-10. A second spur would follow US 83 and connect I-14 to I-10 at Junction. Two more spurs would connect I-14 to I-10 at Beaumont, one on US 69 south from Woodville and the second on US 96 south from Jasper.

This legislation builds upon the original designation, introduced by Rep. Brian Babin as part of the 2015 FAST Act highway bill, and does not eliminate any currently authorized routes. It also authorizes the new interstate route using the general pattern of existing roads and highways, but leaves the final determination about the exact path of the route with state officials and local communities.

New legislation has been proposed to create the Central Louisiana Corridor extending the I-14 corridor eastward following highways LA 8, LA 28 and US 84 in Louisiana through Leesville, Fort Polk, Alexandria, Pineville and Vidalia where it would cross the Mississippi River.

The Central Mississippi Corridor follows US 84 eastward from Natchez to Brookhaven and then to Laurel where it would terminate at Interstate 59. It includes a north-south interstate spur reaching south from Laurel to Gulfport generally following US 49 and passing near the gate at the Army's Camp Shelby. The Mississippi Transportation Commission has approved a resolution supporting the Future I-14 designation pointing to the potential for economic growth in south Mississippi.

 

Texas

 

I-14

The new I-14 Central Texas Corridor follows the US 190 corridor from TX 63 near Jaspar to Hunstville, Bryan, Killeen as studied in 2011. The Central Texas Corridor created in the FAST Act has branch Interstate corridors to Midland, Sonora, and along US 190 to Madisonville with feeder corridors to Beaumont and Corpus Christi. Assuming the mainline corridor for I-14 goes to Midland, then the branch to Sonora could be I-114, and the branch to Madisonville could become I-314. I-14 is also the assumed designation for the 14th Amendment Highway from Natchez Mississippi through Alabama to Augusta Georgia. While Texas is actively planning to build I-14, both Louisiana and Mississippi have withdrawn support for the Gulf Coast Strategic Highway connecting Alexandria Louisiana and Natchez Mississippi. Planning for the 14th Amendment Highway is also at a stand still in Mississippi, Alabama, and Georgia. A conceptual Interstate corridor along US 79 to Austin could be either I-314 or I-214.

I-47

Interstate 47 is an actual proposed branch of the I-14 Central Texas Corridor. The I-14 Central Texas Corridor contained many "feeder" branches to the various ports in Texas such as TX 123/US 181 to Corpus Christi and US 96 to Beaumont. TX 123/US 181 will likely become a four-lane divided highway from I-10 to Corpus Christi. US 96 is mostly a four-lane from Beaumont to Jaspar and connects directly to US 59 in Carthage. US 59 will be converted to I-369 when I-69 is completed in east Texas. Members of the Texas Congressional delegation have suggested the US 96 should be converted to a full Interstate Corridor which could become I-47.

I-6

US 290 Northwest Freeway from Houston to Austin was advocated in 2011 by two Texas Congressmen to become an Interstate corridor that could designated as I-6.

I-27

The proposed I-27 Ports to Plains Corridor extends north from Amarillo into Oklahoma and Colorado and south from Lubbock to Big Spring, San Angelo, Del Rio, and to I-35 near Laredo.

 

Louisiana

 

I-18

I-18 is the proposed designation for a new terrain freeway running from New Orleans, Donaldsonville, Lafayette, Eunice, Kinder, the continuing west to the Texas border at the Sabine River to Jaspar Texas and ultimately to I-20 and I-45 in Dallas Texas. I-18 would start at I-310/LA 3127/Future I-49/U.S. 90 interchange. I-18 follows LA 3127 forming the southern segment of the Westbank Expressway Connector Toll-Road. LA 3127 was actually built in the 1970's with enough right-of-way for a future four-lane highway from I-310 to LA 70 in Donaldsonville. I-518 is the proposed designation for the LA 1 Expressway Toll-Road and the proposed Houma-Thibodaux LA 3127 to U.S. 90 Connector. LaDOTD has been building the LA 1 Expressway toll-road from Port Fourchon to US 90 west extension and now is planning to build the Houma/Thibodaux/LA 3127 Connector initially as a four-lane divided highway the eventually as a fully controlled access highway. I-18 continues west to Lafayette forming a second Atchafalaya Basin freeway crossing, providing and alternative to the traffic congestion of I-10 in Baton Rouge. I-418 forms the northern segment of the Westbank Expressway Connector and I-318 would be the connector to the proposed South Baton Rouge Mississippi River Bridge near Gabriel. West of the new Atchafalya Basin Crossing Bridge, I-18 bypasses south and west of Lafayetter to form the proposed Lafayette Metropolitian Expressway, while I-218 forms the east and north segments of the extended Lafayette Metropolitan Expressway. An I-118 spur connector runs from I-18 south of Lafayette, bypassing east of Abbeville, crossing the Vermillion River with a high-level bridge between the Port of Vermillion and Intracoastal City, terminating at LA 82. The routing of I-18 becomes the alternate to I-10 for traffic to and from Houston to New Orleans. I-18 continues northwest to Eunice to run generally follow US 190 to Texas. I-18 then runs northwest to Dallas Texas forming a New Orleans to Dallas cross-link that avoids I-10 to Houston and I-45/I-20 to Dallas.

I-53

I-53 is the proposed designation for the proposed US 165 Freeway from Lake Charles to Monroe. South of Lake Charles, I-253 extends from I-53 to the Port of Lake Charles. I-53 could bypass Alexandria to the west, connecting the Alexandria International Airport, or it could be routed with I-49 through the city. I-53 continues to follow the US 165 freeway with new freeway bypasses around many of the towns as appropriate. I-53 then becomes the "I-69 Spur Extension" studied by LaDOTD and the Arkansas Highway Department in 2009 and is the conversion of the I-530 "I-69 Spur" that is part of the I-69 project in Arkansas. I-53 would connect to I-30 and I-40 in Little Rock Arkansas. Congress recently created the Future I-57 Interstate Corridor and plans to convert the existing US 67 freeway northeast of Little Rock to I-57, then complete the freeway to US 60 in Missouri. The existing US 60 four-lane highway will also be converted to I-57 eastward to connect to the existing I-57 in Sikeston Missouri. The combination of I-53 and I-57 forms a continuous trade corridor freeway from Chicago Illnois to Lake Charles. Altogether the I-18 system with I-53 links all the southern ports of Louisiana. The ports at Baton Rouge/Port Allen, the Port of South Louisiana along the Mississippi River, and the Port of New Orleans are all connected by the I-18/I-418 Westbank Expressway. Port Fourchon is connected by I-518. The ports south of New Orleans along the Mississippi are connected by completing the LA 23 four-lane to Venice. The other ports in southwest Louisiana could be linked through a secondary system of four-lane divided highways like LA 27 and LA 82 to Cameron, the Sabine Pass, Freshwater City, and the Port Vermillion/Intracoatal City via I-118 south from Lafayette.

I-14

I-14 was first proposed in the 2005 MAP-21 Act under the title "The 14th Amendment Highway" envisioned to extend from Augusta Georgia to Natchez Mississippi. A feasibility study was completed and came to the conclusion that projected traffic need was low for this particular route. Support in state transportation departments in Georgia and Alabama never really formulated. Mississippi and Louisiana were more receptive especially after Texas took the initiative to create the Central Texas Corridor.

A new bill (H.R. 6111) was introduced into the U.S. House of Representatives to extend the Future I-14 corridor created by Congress in 2015 FAST Act through Texas know as the Central Texas Corridor. If this bill is formally approved into law it will become the "I-14 Expansion and Improvement Act of 2018".

The proposed I-14 expansion begins from the Central Texas Corridor that generally follows U.S. 190 through Texas, adding the Central Louisiana Corridor that generally follows LA 28 through Louisiana, and the Central Mississippi Corridor that generally follows U.S. 84 through Mississippi. The Future I-14 could become part of the conceptual Acadian Xpressway Toll-Road System to complete the route through Louisiana sooner within the 2020-2040 time period sooner than the 2040-2050 time frame more likely if the traditional Federal and state budgeting process is followed, waiting for funding in competition with other national transportation projects, usually given a low priority because it is a future Interstate and not an existing Interstate.

Mississippi

 

I-14

I-14 would continue along U.S. 84.

I-14N

 

Alabama

 

I-36 Corridor V

Corridor V consists of US 72 in Alabama. I-36 is the suggested designation for TEA-21 High Priority Interstate Corridor 11, also Corridor V in the Appalachian Development Highway System, consisting of AL 24 to Decatur, I-565 to Huntsville, and US 72 to I-24 west of Chattanooga Tennessee.

I-14 Gulf Coast Strategic Highway/14th Amendment Highway

The I-14 Gulf Coast Strategic Highway and Fourteenth Amendment Highway continue from Mississippi following US 84 to Grove Hill then follows a completely new terrain route to I-65 at Greenville, continuing north along I-65 to Montgomery and east along I-85 and US 80 to Columbus Georgia. The I-85 extension proposed by ALDOT travels along the Montgomery Outer Loop then runs east as a new terrain route to I-20.
