Corridor Issues

Safety

  • The crash rate on I-66 is higher than the Virginia interstate average
  • Emergency vehicle access is hindered
  • HOV lane shifts are confusing

Transit Characteristics

  • Metrorail Orange Line ridership has increased 25% at Fairfax County stations from 1995 to 2001
  • VRE Manassas Line ridership is up 52% from 1995 to 2001

Highway Characteristics

  • Travel demand is up 33% since 1994. Daily traffic volumes range from 45,000 to 190,000 vehicles per day approaching the Capital Beltway
  • As many as 90,000 additional vehicles are expected in the corridor by 2025
  • During peak periods, speeds in the prevailing direction of travel are less than 20 mph

Intermodal Relationships

  • No direct bus connections exist from HOV lanes to Metrorail stations
  • Fewer transit choices west of Route 123
  • Limited bike/pedestrian access along and across I-66


Next Steps

  • Develop preliminary alternatives
  • Hold next round of public meetings in Winter 2002/2003
  • Distribute study materials to local public venues, including colleges and libraries
  • Continue conceptual multimodal engineering, environmental impact analysis, and transportation analysis

Study Background

The I-66 Multimodal Transportation and Environmental Study (I-66 Study) was initiated by the Virginia Department of Transportation (VDOT) and the Department of Rail and Public Transportation (DRPT), in October 2001 to examine ways of improving mobility along the approximately 24-mile I-66 corridor between I-495 in Fairfax County and U.S. Route 15 in Prince William County. Study methods, including technical analyses, public involvement procedures, and alternatives analysis, are being conducted in accordance with the National Environmental Policy Act of 1969 (NEPA), and will eventually be documented in an Environmental Impact Statement (EIS) prepared jointly by the Federal Highway Administration (FHWA) and the Federal Transit Administration (FTA). Building on the findings of the 1999 Major Investment Study (MIS), the current study will look in more detail at multimodal transportation improvements including highway, HOV, bus, and rail.


Current Study Status

  • Initial scoping process completed
  • Base mapping compilation completed
  • Traffic data collection completed
  • Workplace surveys completed
  • Environmental field data collection underway
  • Conceptual multimodal alternatives development initiated
  • Existing/future year travel demand modelling underway
  • Siting analysis for new transit stations and facilities underway
  • Information kiosks stocked with I-66 newsletters
  • Website updated


Scoping Summary

Scoping is a process used to identify the range of alternatives, impacts, and significant issues to be addressed in an EIS. The process includes input from the general public, the Technical and Local Advisory Committees established for the I-66 Study, and appropriate federal, state, regional, and local agencies.

Public and agency meetings are an important element of scoping the study. Public Scoping Meetings were held on January 22, 23, 24, 2002, in Centreville, City of Fairfax, and Manassas, respectively. The meetings were attended by approximately 110 people total, and involved one-on-one interaction between citizens and Study Team members. In addition, 29 representatives participated in a meeting for federal, state, regional, and local agencies.

The Scoping Process yielded suggestions from 81 different commentors, dated on or before the scoping comment deadline of February 8, 2002.

The Study Team reviewed all comment forms, letters, and verbal comments, and broke them down into 323 individual comments. Those comments were grouped into topical categories, based on common themes.

The five most common comment themes were:

  • Alternatives
    Examples: Ideas for multimodal alternatives to include in the study, such as, extension of Metrorail and VRE service, expanded bus service, and adding general purpose/HOV lanes

  • Transportation
    Examples: Traffic bottlenecks at specific locations, the potential effects of other transportation studies and projects, logistics of HOV lane connections, and transit connections

  • Design
    Examples: Interchange and multimodal design, boundaries of design

  • Environmental
    Examples: Air quality, noise, parks, stormwater, land use

  • Implementation
    Examples: Funding, cost to community, timing
    • By a wide margin, bicyclist and pedestrian access was the most frequently raised issue. There was a desire for the design of bicyclist and pedestrian access adjacent to and across from the I-66 corridor in the study area and to avoid conflicts with proposed bikepaths.
    • The second most frequently raised issue dealt with the relationship between transportation and land use growth patterns. Requests for the study to examine region-wide alternative land use scenarios and to examine integrated land use and transit alternatives were provided.

While the initial scoping process is complete, the Study Team will continue to solicit and evaluate public and agency input to ensure that a reasonable range of alternatives are considered in the Draft Environmental Impact Statement (DEIS).

Existing Traffic and Travel Data

One of the early efforts of the I-66 Study was to compile and collect traffic and transit travel related data. Traffic counts were recorded along the I-66 mainline lanes and for each interchange ramp and associated intersection. Current daily traffic volumes range from 45,000 vehicles per day at the western limits of the study to up to 190,000 vehicles per day approaching the Capital Beltway at the eastern limits of the study. Depending on locations along the corridor, traffic within the study area has grown by an average of 33 percent since preliminary I-66 volumes were taken in 1994. Growth in the western portion of the corridor is even more dramatic, with up to a 59 percent increase since 1994.  

Along with increased traffic volumes, demand for transit has increased. Virginia Railway Express (VRE) ridership for stations near the I-66 corridor increased 52 percent from 1995 to 2001 to a total of about 4,700 riders each day. In recent years, VRE ridership has continued to grow at a rate of 12 to 16 percent each year. The Metrorail Orange Line, which serves the I-66 corridor from Vienna eastward, reported a 25 percent increase in people boarding at stations in Fairfax County (west of the East Falls Church station) since 1995. The Orange Line in Fairfax County currently serves about 23,000 weekday boardings, contributing considerably to person throughput in the I-66 corridor.


Environmental Review Process

The I-66 Multimodal Transportation and Environmental Study (MTES) is a detailed design and environmental study being undertaken in accord with processes identified through NEPA (National Environmental Policy Act of 1969). This process, which requires continual public outreach and agency involvement, is outlined in the chart below.
