New roads and bridges will be built, more money will be dedicated to Interstate improvement, and funding will be set aside for emerging needs under a plan approved by the State Transportation Commission. Now the selling begins. Transportation officials presented the commission three options. The Commission chose the one that spends the most on new projects and the least on improving the existing system. In August, voters will decide whether to increase the fuel tax by four cents and the sales tax by a half-cent to raise an additional $500-Million a year for the state transportation system. The Commission approved a plan that spends 57-percent of the new money on the existing system, the rest on new projects and Interstates. It sets aside 15-percent of the money in reserve for projects that might emerge in the next ten years.
