A month after a fare increase took effect, the Transit Authority of River City will alter several of its routes, effective Sunday.Five routes will be eliminated and ten more will be altered. These cuts and more were proposed this spring after TARC saw a drop in revenue. After a flood of public comments, TARC instituted a rate increase but held off on changing some routes.Most of TARC's money comes from the city occupational tax, and while officials were considering what routes to change, revenue increased. Also, TARC's diesel fuel bill dropped, and the authoritywas able to avoid deeper cuts in service.With uncertain day-to-day funding, TARC has taken to seeking more federal assistance to replace buses. About ten percent of the fleet will be replaced in the coming year thanks to grants from Washington, D.C.
