bike lanes

I guess The City of Modesto adopted the "Non-Motorized Transportation Master Plan" back in 1996 and some good things have been done with this plan like the 2.5 mile Hetch-Hetchy Trail and the 5 mile trail along Dry Creek, but where are the bike lanes that can get people from point A to point B safely using ALL major surface streets? Is it too late to make room for bikers on ALL of Modesto's roads? What are the options? What are the major financial roadblocks?
