Some Chapel Hill Town Council members have doubts that a plan to widen Weaver Dairy Road, which they approved and sent to the N.C. Department of Transportation this week, will be accepted. The council voted 6-3 Monday to approve a plan that would expand parts of Weaver Dairy Road, a two-lane road, to three lanes. The earliest the plan would be approved by NCDOT is next week. The council had approved a similar measure Jan. 22, 2001, but NCDOT did not approve that plan. NCDOT instead had recommended a four-lane road.
