CEDAR RAPIDS — A proposed $9.65 million stretch of Tower Terrace Road — from Alburnett Road in Marion to Summerset Avenue NE, just west of C Avenue NE in Cedar Rapids — is taking another step toward reality.City councils in both cities have the road-building project on their agendas, as members decide on a cost-sharing agreement for the portion of the project not covered by $6.9 million in federal funds.The Cedar Rapids council’s Infrastructure Committee voted this week to recommend the sharing arrangement with Marion.
