The Delmar Loop Trolley construction project took another step forward Wednesday, as crews poured the first rounds of concrete around the trolley tracks.
Project officials said crews will use 35 truck-loads of concrete on the first section of the $43 million project, before moving on to the next phase.
On Thursday, the first section will be finished.
The entire project is expected to reach completion by summer 2016.
