Traffic and parking in downtown Woodbury will be limited today due to the paving of two downtown streets. North Cannon and North Tatum streets will both be blocked off during the paving. North Cannon will be paved first and should be open by Thursday, according to Terry Preston of Preston Brothers Construction. North Tatum will be paved Thursday, Preston said, and should open to traffic again on Friday. The work is part of the final phase of the Cannon County Courthouse Revitalization Project.
