Cincinnati city officials say the streetcar project has been delayed again, this time to the spring of 2016.The latest timetable is outlined in construction bid documents recently issued by city hall. Two ballot measures drafted by streetcar opponents slowed the process, even though Cincinnati voters rejected efforts to scuttle the project. The 3.6-mile 110-million dollar streetcar will run from the downtown riverfront to Over-the-Rhine. City officials say it will help attract new businesses, visitors and residents to the revitalized downtown. Opponents say it will do little for the city.
