Mayor Karl Dean cut the ribbon to the Music City Center Monday morning.
The ceremony began at 9 a.m. at the brand new convention center in downtown Nashville.
During the ceremony Dean announced that more than 1 million rooms have already been booked for the convention center which spans six blocks.
"The bookings to date reflect the excitement in the industry around this project," Mayor Dean said. "All it takes is a visit to Music City to see why we are now the nation's best convention and event destination. We are not just opening the doors of a new downtown convention center, we are opening a new world of opportunity for Nashville's hospitality and tourism industry."
Sunday over 15,000 people took a tour of the new convention center.
Parking at the Music City Center will be a breeze, with nearly 1,800 parking spaces for guests and the public to use.
Larry Atema, Sr. Project Manager of MCC said one of his most memorable moments during the project was the excavation. "It's fun it's lively, it's a little bit unpredictable." He added that one of his favorite features is the ballroom level.
He said that one of his favorite things about the project is that it provided thousands of jobs to local, under and unemployed workers.
"Over 7,500 people have helped build this building. In addition to that, 30 percent of the work was done by small, women-owned, minority businesses, which represents, $135 million of the work, or 30 percent," explained Atema.
Monday marks over a three-year cap on the project since the ground breaking in March 2010.
In addition to Monday's ribbon cutting ceremony, the community is welcomed back for an open house beginning at 5 p.m. with a grand opening concert at 6 p.m. The concert will feature music by The Time Jumpers with Vince Gill, The Fisk Jubilee Singers, Mikky Ekko and Sheryl Crow.
