An appeal has been filed to An Bord Pleanála on a major neighbourhood centre development in Offaly.
The County Council approved the proposal in November subject to 19 conditions.
Developers Cedarglade Limited are appealing against conditions around amendments to the roundabout and associated junctions.
The project includes a convenience retailer, cafe and pharmacy on Collin's Lane in Tullamore.
The conditions insisted on amendments being completed before first operation of the proposed supermarket and final designs of the roundabout to be submitted to the Planning Authority.
A decision is due from the planning body by the end of April.
