 The Bicycle Transportation Alliance grew into one of the most effective cycling advocacy organizations in the U.S.The BTA focused on making major streets safe for cycling by advocating bicycle lanes, improvements to all seven pedestrian-accessible Willamette River bridges linking the downtown to the rest of the city and for safe, secure bicycle parking.In 1992, BTA successfully sued the City of Portland under ORS 366.514, the Oregon "Bicycle Bill," forcing the City to provide bicycle facilities as part of all projects.
