Above the arch junctions with the pier, the piers have open areas to reduce the weight on the pier.   An ornamental balustrade is also made of poured concrete. 
   
Four ribs are used in this part of the bridge approach.   Residential areas are found at this approach to the bridge on the Allentown side.
