Wisconsin Center expansion concrete pour, downtown Milwaukee

MILWAUKEE - Expansion of Milwaukee's Wisconsin Center reached a major construction milestone on Tuesday, May 10.

Crews poured approximately 450 cubic yards of concrete Tuesday. The pour was part of the convention center's storm trap. It will serve as a water storage system to slow down the amount of stormwater entering the street's sewer system – and reduce water runoff on the streets.
