FHWA Alternative Fuel Corridors for Louisiana Announced

    Advancing America's 21st Century Transportation Network

    Via fhwa.dot.gov - With the designation of alternative fuel corridors, FHWA is establishing a national network of alternative fueling and charging infrastructure along national highway system corridors. FHWA intends to support the expansion of this national network through a process that:

    • provides the opportunity for formal corridor designations on an annual basis;
    • ensures that corridor designations are selected based on criteria that promote the "build out" of a national network;
    • develops national signage and branding to help catalyze applicant and public interest;
    • encourages multi-State and regional cooperation and collaboration; and,
    • brings together a consortium of stakeholders including state agencies, utilities, alternative fuel providers, and car manufacturers to promote and advance alternative fuel corridor designations in conjunction with the Department of Energy.

    Rounds 1 and 2 (FY 2016 and FY 2017) of FHWA's Alternative Fuel Corridor Designations, have included:

    • 58 Nominations;
    • Segments or entire lengths of 71 Interstate corridors (including Hawaii);
    • 44 states (plus the District of Columbia) designated as corridor-ready or corridor-pending for one or more alternative fuel types. (https://www.fhwa.dot.gov/environment/alternative_fuel_corridors/)

    LCF worked closely with the state's Department of Environmental Quality to complete their proposal to the FHWA. We participated in and helped lead two outreach meetings with the DEQ and worked with the Capitol Region Planning Commission to create maps of our fueling infrastructure that were used in both presentations and in the final proposal to FHWA.

    In order for an interstate to qualify for AFV Corridor signage in Round 2, the following requirements must have been met:


    Signage Ready NHS Segment

    Signage Pending NHS Segment has…

    EV Charging

    Public DC Fast Charging no greater than 50 miles between one station and the next on corridor

    Public DC Fast Charging chargers separated by more than 50 miles


    Public, primary propane stations no greater than 150 miles between one station and the next on the corridor

    Public, primary propane stations separated by more than 150 miles


    Public fast fill, 3,600 psi CNG stations no greater than 150 miles between one station and the next on the corridor

    Public, fast fill, 3,600 psi CNG stations separated by more than 150 miles


    Public LNG stations no greater than 200 miles between one station and the next on the corridor

    Public LNG stations separated by more than 200 miles 


    We are excited to announce that multiple corridors have been approved for signage for the following fuels in Louisiana: CNG, Propane and LPG. To see how our state stacks up against the rest of the country, and to view which corridors have been approved (and which are pending), please visit the FHWA AFV Corridors website and select "Maps".

    You may be wondering why we do not currently have any approved electric charging corridors. Under the program requirements, in order to get an interstate designated as an EV charging corridor, you mush have public DC Fast Chargers every 50 miles. While we have over a hundred level 2 chargers in our state, Louisiana only has one public DC Fast charger that is not also a Tesla Super-Charger. Since the Tesla chargers are proprietary only to Tesla owners, they do not count as "public" under this signage program.

    Moving Forward

    The next step in this program is to get the highway signage fabricated and installed on the corridors shown below. The Louisiana DEQ and LCF will work with our DOTD on this next exciting phase.  Additionally, in order to help spur the installation of a fast charging network in our state, LCF has begun working with its stakeholders to create a statewide DC Fast Charging Master Plan. We will also continue to work with our stakeholders to both improve and support the current CNG, Propane and LNG corridors.
