The City of Ames is using the reconstruction of Clark Ave. south of the railroad tracks near downtown to try out a pilot project aimed at better intigrating bicycles into street traffic. Civil engineer Mark Gansen says they're using green-painted "bike boxes" at the intersection of Clark and Lincoln Way to put cyclists ahead of stopped car traffic. He says cyclists will use the on-street bike lanes to move into the boxes, ahead of the white stripe where cars and trucks have to stop. He says they'll look at how the existing bike boxes work for possible use in other parts of the city. By the way, Gansen says the establishement of bike boxes means a change in driving habits--he says vehicles are no longer allowed to make a right turn on red at that Clark and Lincoln Way intersection.
