Indianapolis -- A city zoning board will vote Jan. 5 on a variance request by Flaherty & Collins to erect a billboard-size sign along I-465 to advertise its Westlake Apartments, near the 10th Street interchange. The 22-foot-tall sign would project over a noise barrier wall. Zoning staff said the sign is larger than rules permit and, if approved, could lead to a profusion of similar signs along the interstate loop.
