Cincinnati officials Monday signed a contract for construction work on the city's controversial streetcar system. 

The action means Cincinnati-based Messer Construction and two other firms can proceed with the project.  That includes ordering materials, and beginning track construction, plus the power system, the stations and a maintenance and operation facility located at Race and Henry Streets. 

The city says the system could be ready for passengers on September 15, 2016.
