Republican mayoral candidate Hal Heiner says public outcry could force a change in the Ohio River Bridges Project.Heiner has previously stated his opposition to using tolls over one dollar to finance two new bridges and a reworked Spaghetti Junction. The mayor does not have a direct say in the Ohio River Bridges Authority's decisions on the project. But Heiner says he would lobby the authority to keep tolls low."If it came out tomorrow that it was going to be a $6 round trip to Indiana, there would be a cry that would go up in this community, because it would split our economic region in half. Hopefully the Bridges Authority will hear that cry, but I will be in there advocating, doing everything I can to make sure we find a more affordable way to build that project."Heiner also says the Spaghetti Junction rework should be scaled down and the east end bridge should be under construction in the next four years. Democratic candidate Greg Fischer says he opposes excessive tolls, and may support changes to the project once a financing plan is released later this year. Independent Jackie Green favors shelving the project. Heiner made his comments on WFPL's State of Affairs Monday.
