This is a list of current and future High Occupancy/Toll lanes, express toll lanes, and hybrid systems in the United States.

Abbreviations used on this page: SOV (Single-occupancy vehicle); HOV (High-occupancy vehicle); HOT (High occupancy/toll); ETL (Express toll lane). On this page, the word hybrid is used to indicate systems that are part HOT and part ETL.

Current HOT lanes

The following roads currently use HOT lanes:

California

• Interstate 15, San Diego County. SOV toll ($0.50-$8.00); HOV-2+ free. ^[1]

Colorado

• Interstate 25 between 20th Street in Downtown Denver and the US-36 interchange. SOV toll ($0.50-$3.50); HOV-2+, motorcycles, buses free. ^[2]

Florida

• Interstate 95 So far, only Phase 1 (northbound and southbound, between I-195 and the Golden Glades interchange) has been opened. Motorcycles, registered HOV-3, hybrid, vanpool, and buses ride free.)^[3]

Minnesota

• Interstate 394, MnPASS Minneapolis, from I-494 to TH 100. ^[4] SOV toll ($0.25-$8.00); HOV-2+ free. ^[5]

Utah

• Interstate 15 between 600 N in Salt Lake City, Utah and University Parkway in Orem, Utah. SOV toll ($50/mo.); HOV-2+/clean-fuel free. This is not truly a HOT or ETL project, as it operates by selling permits instead of collecting a toll. There is a maximum of 2,000 permits that will be sold. ^[6]

Washington

• SR 167, HOT Lanes opened July, 2008, Auburn to Renton. SOV use of HOV toll lane ($0.50-$9.00); HOV-2+ and motorcycles free. ^[7]

Future HOT lanes (including studies underway)

California

The Bay area is planning an entire network of HOT lanes.^[8]

• Interstate 680 Under construction.^[9] Expected to open in 2010.^[10] The portion being constructed is the Sunol grade.
• Interstate 580 Under construction. Expected to open in 2010.^[10] The portion being constructed is in the Tri-Valley area.
• U.S. 101 Planned. ^[11] The areas to be constructed include the total area of the Metropolitan Transportation Commission (San Francisco Bay Area) (MTC), with the exception of the City of San Francisco, the northern approach to the Golden Gate Bridge, and northern San Mateo County.^[12]
• Interstate 80 Planned. The areas to be constructed include the total MTC area, with the exception of the City of San Francisco, and the approach to the San Francisco – Oakland Bay Bridge. ^[12]

Riverside county

Riverside county is recognized by the California Transportation Commission(CATC) as having a traffic congestion problem second only to Los Angeles. ^[13]

• SR 91 Recommended. Two HOT lanes and a mixed-flow lane from the Orange county line to the intersection with I-15. ^[13]
• Interstate 15 Recommended. Two HOT lanes and a mixed-flow lane from the San Bernardino county line to the intersection with SR 74. Further, an HOV lane and an eventual HOT lane extension to the San Diego county line. ^[13]

Los Angeles county

Los Angeles county has a plan in place that has been approved by the California legislature. ^[14] They have received a grant for $213.6 million from the USDOT(US Department of Transportation). This plan will be implemented in two phases, although it is currently unknown when those phases will take place. ^[15]

Both phases are for the conversion of HOV lanes to HOT lanes.

• Interstate 10 Phase 1: Convert the San Bernardino Freeway HOV lanes from Alameda St/Union Station to the intersection with I-605. Phase 2: From I-605 to SR 57: in design; from SR-57 to the San Bernardino county line. ^[15]
• Interstate 210 Phase 1: Convert the Foothill Freeway from I-710 to I-605. Phase 2: From I-605 to the San Bernardino county line. ^[15]
• Interstate 110 Phase 1: Convert the Harbor Freeway from 182nd St./Artesia Transit Center to Adams Blvd. ^[15]
• SR 60 Phase 2: Convert from the intersection with I-605 to Brea Canyon (under construction), and convert from Brea Canyon to the San Bernardino county line. ^[15]

San Diego county

• Interstate 15 Extension of already-existing HOT lanes. "Stage 3": From SR 163 to SR 56(Ted Williams Pkwy) (under construction). "Middle Stage A&B": from SR 56 to W. Bernardo Dr. (under construction; partially complete). "Stage North": From W. Bernardo Dr. to SR 78 in Escondido. ^[16]

Florida

• Interstate 95 will be done in phases. Phase 1A was opened 12/2008. Phase 1B is expected to launch in 2009 on southbound lanes between the Golden Glades Interchange and I-395, and on northbound lanes between I-395 and I-195. Phase 2, from the Golden Glades Interchange to I-595 in Broward, is expected to launch in 2010. ^[3]

Georgia

• Conversion of the existing HOV lanes to HOT lanes on Interstate 85 has been approved to relieve the congestion in the DeKalb County portion of the Northeast Atlanta region. This would be done from Chamblee-Tucker road south of the I-285 junction to Old Peachtree Road in Gwinnett County. HOT lanes on I-85 are expected to be in service by 2011.^[17]

Illinois

• 25px Illinois Tollway System "Green Lanes" (really, HOT lanes) are to be added to all roadways in the Illinois Tollway System. The lanes could begin operating as early as 2010. All Chicago-area tollways will have "green lanes" by 2015. ^[18] Suspended after former Governor Rod Blagojevich, who suggested the idea, was arrested, impeached, and removed.^[19]

Minnesota

• Interstate 35W Segment 3: From SR 65/I-94 split to 42nd St. This will be a Priced Dynamic Shoulder Lane (PDSL) (a type of HOT lane). Scheduled to open 9/2009. Segment 2: From 42nd St. to 66th St. This is an HOV to HOT conversion project. Scheduled to open 2010. Segment 1: From 66th St. to Burnsville Parkway (see Burnsville, Minnesota). This is an HOV to HOT conversion project. Scheduled to open 2011. ^[20]

New York/New Jersey Port Authority

• The Port Authority of New York and New Jersey is studying the concept of merging HOT lanes with the existing XBL (eXclusive Bus Lane) lanes in the Lincoln Tunnel. ^[21]

North Carolina

• Interstate 77 Charlotte, from I-85 to SH 2158 (Griffith Street) at Davidson, Mecklenburg County. Extend existing HOV Lanes, convert HOV Lanes to HOT Lanes and evaluate shoulder use lanes. Under study. ^[22]

South Carolina

All South Carolina projects are under study.

• Interstate 77 From the intersection with U.S. 21 to the North Carolina state line. This highway portion is very heavily used, and so HOT lanes is one option being studied to relieve congestion. ^[23]
• Interstate 26/Interstate 126/Interstate 20 Projections are that traffic on these interstates will double by the year 2030. A corridor taskforce has been in place to study all the possibilities for managing the anticipated traffic growth. All these could accommodate HOT lanes. ^[23]
  • These are the only segments that would support widening for HOT lanes:
    • A 7.22 mile segment of I-26 from the intersection with I-126 to the intersection with U.S. 321.
    • A 6 mile segment of I-20 east of I-77 to the northeast section of Richland County. No funds are currently available.
  • These segments could not be widened, but are still being considered for HOT lanes:
    • A 9.22 mile segment of the I-26/I-126 corridor from U.S. 176 to U.S. 21.
    • A 14.45 mile segment of I-20 from the northeast section of Richland County to the intersection with U.S. 378.
• Interstate 385 A 6.45 mile segment of I-385 from east of I-85. This segment could be widened for HOT lanes; however, no construction funds are currently available. ^[23]
