Forsyth County may soon take a big step forward on building a big event center at Tanglewood Park, making it possible for the county to hold concerts, expositions and other indoor events like Winston-Salem does at the fairgrounds. The Forsyth County Board of Commissioners are expected to vote on July 29 whether to enter into a contract with Shelco LLC for a maximum amount of $450,000 for design and other pre-construction services on the center, which has a $5 million budget. Shelco would use the services of Walter, Robbs, Callahan & Pierce-Architects for architectural work. Tanglewood Park is moving forward with plans for an event center that would be larger than both the Annex and Education buildings at the Winston-Salem Fairgrounds.
