The Alternative Fuel Corridors Program
3
Section 1413 of the Fixing America’s Surface Transportation (FAST) Act requires
the U.S. Secretary of Transportation to designate alternative fuel corridors.
The program is administered by the Federal Highway Administration (FHWA) in an
effort to improve/promote an interstate network of stations in which to enhance
the reliability/mobility of alternative fuel vehicles.
Designated national corridors along major highways are identified by fuel type:
 Plug-In Electric Vehicle Charging
 Hydrogen Fueling
 Propane (LPG) Fueling
 Natural Gas (CNG, LNG) Fueling

Benefits of a National System

Alternative Fuel Corridor Designation Process
5
• States apply to FHWA for Alternative Fuel Corridor designation
• FHWA reviews applications and designates a corridor either as:
Corridor/Signage Ready-A sufficient number of facilities exist on
the corridor to warrant installation of highway signage (by fuel
type)
Corridor/Signage Pending-An insufficient number of facilities
currently exist on the corridor to allow for reliable corridor travel

FHWA’s Corridor-Ready Criteria

Connecticut’s Alternative Fuel Corridors

Connecticut has been a participant in FHWA’s Alt. Fuels Corridor Program since 2016
The following Interstate highways are “Signage-Ready”
EV: I-84 (NY border to MA border)
I-91 (New Haven to MA border)
I-95 (NY border to RI border)
I-395 (Waterford to MA border)
CNG: I-91 (New Haven to MA border)
I-95 (NY border to RI border)
LPG: I-84 (NY border to MA border)

Why focus on Alternative Fueled Vehicles?

2016 Connecticut GHG Emissions by Sector
2016 Connecticut Greenhouse Gas Emissions Inventory. Connecticut Department of Energy and Environmental Protection. Retrieved July
30, 2019 from https://www.ct.gov/deep/lib/deep/climatechange/publications/ct_2016_ghg_inventory.pdf.
Work towards meeting Connecticut’s GHG emission targets
Our mid-term GHG target is 45% below 2001 levels by 2030

Why focus on Alternative Fueled Vehicles?

To attain compliance with federal health-based air quality standards
2008 and 2015 NAAQS for ground-level ozone
CT air quality monitors record some of the highest ozone levels on the east coast
especially along heavily-trafficked transportation corridors where criteria air
pollutants are most densely concentrated.

Connecticut’s Commitment to Alternative Fuels

Current and Near Term Activities
11
 CT DOT, CT DEEP & the CT Clean Cities Coalitions attended the
Northeast/Mid-Atlantic Alt. Fuel Corridor Convening in
Providence, RI (July 2019)
 In September, CT received notification from FHWA that our
state EV corridors met the revised designation criteria and we
are cleared to proceed with installing Alt. Fuel Corridor
signage
 CT DOT is pursuing steps to install Alt. Fuel Corridor signage on
CT Signage ready corridors
 CT DEEP & CT DOT will be working together to apply for a
Hydrogen Alternative Fuel Corridor in the near future
