Oregon's Bike Bill (ORS 366.514) generally requires communities to
provide sidewalks and bikeways when building or rebuilding a road. Communities
also must spend at least 1% of their State Highway Fund dollars on walking and
biking.
But for communities who want to do more, this page lists some funding options. It does not imply endorsement, is not an exhaustive list, and programs evolve over time. Most sources not connected to the Highway Trust Fund can be used
outside the road right-of-way.
The current list is in this eight-page PDF version of this document which can be downloaded here:
