The Milwaukee Streetcar construction along St. Paul Avenue is in the "most advanced stage" according to construction officials, as crews poured the first concrete along the line setting the rails Wednesday.

"We're on schedule, spring work can present challenges because you get all types of weather in spring,” said Construction Manager Carolynn Gellings. “All of this work is very weather dependent."

In Detroit last weekend the city opened the "Q-Line," a system largely designed by the same company and uses the same vehicles from Brookfield Equipment Corporation as the Milwaukee line does. TODAY'S TMJ4 sister station WXYZ-Detroit reports a few hiccups with the launch.

Long wait times, mechanical problems, and a car having to be towed from the tracks were reported.
