Allegheny County Parks will be hosting a concert this Sunday July 27th at Hartwood Acres on Middle Rd. Heavy traffic can be expected at various times throughout the day. Traffic flow will be further impacted by Harts Run Rd (between Woodland Rd and Rosanna Dr) being closed for repairs during this time. Drivers should find alternate routes to avoid Middle Road especially between Wildwood Road Extension and Harts Run Road. Heavy congestion is also to be expected on Harts Run Road to Saxonburg Blvd. in Indiana Township.
