Sustainable Highways Initiative

More Transportation Agencies across the U.S. Using INVEST

Transportation agencies across the United States are using INVEST to evaluate and improve the sustainability of their projects and programs. The map below shows the locations of active or recently completed INVEST projects while the table below provides a brief description for each project, listed alphabetically by state. More detailed information on some of the projects is available on the case studies section of the website and additional case studies will be added continuously.

Please note: This list is not comprehensive. Since usage of the online tool is confidential, FHWA is only aware of INVEST projects when agencies inform us they are using the tool. If your agency is using INVEST and would like to be included on the list, please contact sustainablehighways@dot.gov.

State Agency Location Project Description
Multiple Federal Lands Highway Multiple Federal Lands Highway recently initiated or completed INVEST evaluations on 28 transportation projects and programs on national parks, wildlife refuges, national forests, and other federal lands across the country. Federal Lands Highway is using INVEST to improve sustainability in a number of ways: The Western Division uses the INVEST project development module to select the recipient of its Annual Sustainability Award and to pinpoint areas where the agency can make programmatic adjustments to processes, maximizing sustainability improvements. The Eastern Division is working with managers at multiple wildlife refuges in Maryland and Virginia to improve operations and maintenance practices. The Central Division used INVEST to evaluate the sustainability of the Halstead Meadow Bridge project in Sequoia National Park. That project replaced roadway fill with a bridge, restoring the ecology of the meadow by restoring water flow that had been blocked by the fill.

IL Illinois Tollway Chicago The Illinois Tollway is using all three INVEST modules. The tollway is using the project development module to assess the sustainability of a set of 18 completed transportation projects in order to set a baseline. Next, the tollway is evaluating and improving 8 in-progress projects that are part of the tollway's fifteen-year, $12 billion capital program. Finally, the tollway is using the system planning module to evaluate its long range planning and capital program development processes, and the operations and maintenance module to evaluate and improve the operations and maintenance program.

Planners communicated INVEST criteria effectively and concisely through a visual format.
IN Indianapolis MPO Indianapolis The Indianapolis MPO plans to use INVEST for its long range transportation plan update.
KY Kentucky Transportation Cabinet Multiple The Kentucky Transportation Cabinet (KYTC) sponsored University of Kentucky researchers to analyze three highway projects in the state using INVEST on a trial basis. The researchers found that the three projects met the bronze level of sustainability with INVEST and identified additional practices that could bring similar projects up to a platinum level of sustainability at modest cost. KYTC is researching the use of INVEST on three additional highway projects.
MA Cape Cod Commission Hyannis The Cape Cod Commission used the INVEST system planning module to inform the development of their regional transportation plan and the project development module to guide decision-making on transportation projects in the Hyannis Access Plan.
MA Massachusetts DOT (MassDOT) Statewide MassDOT is using the INVEST project development module to evaluate the Casey Arborway Project, which will replace a 1950s era elevated highway with an at-grade roadway with strong pedestrian connectivity.

OH Northeast Ohio Areawide Coordinating Agency (NOACA) Cleveland NOACA, the metropolitan planning organization for Cleveland, OH, will use the INVEST operations and maintenance module to evaluate the effectiveness of NOACA's regional safety program, improve NOACA's data analysis and reporting, and produce a transportation safety action plan.
OH Ohio DOT (ODOT) Cleveland INVEST helped ODOT improve the sustainability of the largest project in ODOT history, the replacement of the Cleveland Innerbelt Bridge on I-90, now called the George V. Voinovich Bridge. ODOT used the pilot version of INVEST to score the first phase to see if the project was meeting its goals. ODOT found the process so valuable, that for the second phase of the project, the agency stipulated in its request for proposals that the contractor use INVEST to demonstrate sustainability and commit to achieving a certain number of points. This provided a strong incentive for bidders to incorporate sustainability while keeping costs competitive. In fact, the winning bidder committed to achieve a Platinum INVEST rating and bid $19 million below the ODOT official engineering estimate.
OR Lane Transit Eugene Lane Transit is using INVEST to help the agency evaluate its level of sustainability.
OR TriMet Portland TriMet used the INVEST project development and operations and maintenance modules to improve and enhance the sustainability of the Portland to Milwaukie Light Rail Transit Project.

RI Rhode Island DOT Multiple Rhode Island DOT (RIDOT) applied the INVEST Project Development module, using multiple scorecards, retrospectively to a segment of a new bike path project. This 2-mile section (Segment 4) is part of the new, 21-mile long bikeway in the Blackstone River Valley. The project scored well on context sensitive development, habitat restoration, and site vegetation. RIDOT plans to use the tool retrospectively on additional projects of varying scope that are common in their program, to help determine the best way to institutionalize INVEST prospectively into their project development processes. RIDOT's next project is a pavement preservation and livable community project in a historic downtown area. New RIDOT initiatives, such as using warm mix asphalt and moving toward requiring a quality control plan by the contractor, should improve the sustainability of future projects.

UDOT will then evaluate some specific UDOT operations and maintenances practices more in-depth using INVEST to examine opportunities for sustainability improvements. These practices may include snow removal, self-performed chip seals, maintenance of low volume roads, and winter maintenance activities.

International Paraguay Ministry of Public Works Tavai INVEST has also received interest internationally. The Ministry of Public Works for the Republic of Paraguay, working with the Inter-American Development Bank (IDB) on an IDB-funded project, used INVEST to score a 90km road project that passes indigenous communities and wildlife refuges. Paraguay found that their new technical specifications for road projects brought them an increased level of sustainability, but that there was still further to go.
