From wikipedia:
"The bridge is 364 metres (1,194 ft) in length, with the longest span, the arch-supported roadway crossing the Genesee, encompassing 140.9 metres (462.3 ft). In terms of width, the structure is 39.8 metres (130.6 ft) wide.
"The roadway on its surface is eight lanes wide, with four reserved for each direction of I-490. On a daily basis, the structure carries an estimated 71,640 vehicles over NY 383 and the Genesee." (

The arch is designed to allow maintenance workers to maintain the bridge suspension cables and lighting from within the crawl space, thereby providing optimal safety to the worker.
