Construction is set to begin Thursday on the new main entrance Covelli Center sign in downtown Youngstown.

The naming rights of the building, which was formerly known as the Chevrolet Centre, were bought by Sam Covelli of Covelli Enterprises in April.

Covelli is a franchisee of Panera Bread and by the end of 2009 will own and operate more than 150 Panera Bread bakery and cafes  in four states.

Covelli, who has kept his headquarters in Niles, also opened up his fourth O'Charley's restaurant in March and has plans to open up 50 more.
