BELOIT ? Officials unveiled Thursday one of the most expensive highway projects in state history, but it is designed to do more than ease congestion. The $715 million reconstruction and expansion of a 45-mile stretch of Interstate 39-90 between Madison and the Illinois state line will aid state tourism and help create more economic development along the corridor, one of the busiest stretches of highway in the state, officials say.
