Twins Ballpark, the future stadium of the Twins will be located in what is now a parking lot at the north end of downtown Minneapolis within walking distance of the Target Center. The Hiawatha Light Rail line will be extended to the ballpark area with a possible connection with the proposed Northstar Commuter Rail. Preliminary plans call for a seating capacity of 40,000 seats and 72 suites. There will be approximately 34 bathrooms compared to only 16 in the Metrodome. The concourses will be open to the playing field with a view of the downtown Minneapolis skyline from every seat in the park. There will not be a retractable roof on the stadium which would add about $100 million on to the cost which is currently set at $522 million. This has received some objection due to the potentially harsh game conditions in April and even early May, and the resulting lost revenue. Since there will not be a roof, heat can be pumped into the seating areas from a nearby garbage burner. The official groundbreaking for the stadium, originally scheduled for 2 August 2007, was postponed to August 30 due to the collapse of the I-35W Mississippi River bridge nearby. However, officials still expect the work to be completed in time for the 2010 home opener. With the new ballpark bill, a provision was signed into law that allows the state of Minnesota the right of first refusal to buy the team if it is ever sold, and requires that the name, colors, World Series trophies and history of the team remain in Minnesota if the Twins are ever moved out of state (a reaction to the loss of the Minnesota North Stars to Dallas in 1993).
