TDOT: New Clinton bridge to open in August Oakridger Motorists could be traversing the Clinch River in Clinton on a new bridge by the first week of August, with demolition of the old Lewallen bridge to begin in September. "As of now, the contractor anticipates switching two lanes onto the new bridge heading into Clinton the first week of August and switching the other two lanes by the end of (that) week," Mark Nagi, Tennessee Department of Transportation's community relations officer for East Tennessee, stated in an emailed response to the newspaper's questions on Friday. "They would finish installing pipe and demolition should begin shortly thereafter."
