Pittsboro Street between Cameron and McCauley streets, next to the Carolina Inn on the UNC-Chapel Hill campus, remained closed for emergency utility repairs Thursday.
On Wednesday afternoon, engineers checking a utility tunnel that runs under the road noticed some damage to the tunnel's roof. Vibration caused by heavy vehicle traffic directly above the tunnel could exacerbate the damage.
Town and university officials hope that one lane will reopen to traffic in the next several days. Complete repairs so that the traffic flow can return to normal could take six to eight weeks.
