A welcoming reception begins at 5 p.m. and presentations, beginning at 6 p.m., will review developments in bikeway design and planning from Fall River to Wareham. Presenters include Rep. Bill Strauss, representatives from the East Coast Greenway Alliance who will unveil the new nationally advertised bike-touring route through the region.
