PAUL — When developers of the Central Corridor light rail line—now named the Green Line—began construction on the project in 2010, they knew they had to be more than on time and on budget. Community expectations and apprehension were both very high. Now that construction is completed and the trains are set to start running June 14, organizers, residents and business owners are looking forward to reaping rewards that will make the hardships seem worthwhile. The Green Line project, which cost $957 million, will connect the downtowns of St. Paul and Minneapolis along University Avenue, a primary residential thoroughfare between the Twin Cities. It will offer riders stops from the state Capitol to Target Field—home of the Minnesota Twins—with crucial stops in between, including St. Paul’s Frogtown and Midway neighborhoods, the area near state Highway 280 where the cities meet, and the East Bank of the University of Minnesota.
