What is Sustainability?
Improving roads and limiting the impact on the environment.
“The intent of the program is to improve mobility of people and goods in Washington State by supporting economic development and environmentally responsive solutions to our statewide transportation system needs.” --UCP Charter RCW 47.26.086
What are sustainable roads?
Sustainable roads improve the economic and social quality of human life while limiting impacts on the natural environment.

How TIB has implemented sustainability
Starting with the FY 2010 funding programs TIB revised the grant criteria and point systems of the Urban Arterial and the Urban Corridor programs to include a category to support modal, energy, environmental, and recycling measures.  The new criteria encourage customers to consider a range of sustainability measures appropriate to their projects and locale, without forcing any particular measure on the customer.
Examples of Sustainability
Stormwater Infiltration Basin in Planter Strip – Portland, Oregon, USA Photovoltaic Cells – Seattle, Washington, USA
