Origin of trips on Regents Rd bridge

According to the DEIR, the bridge would do little to draw traffic from Genesee Avenue. The majority of the additional traffic on Regents Road would be regional traffic, drawn from the freeways. Here's how to figure this out. Look at the table of segment ADT and compare the "no project" and "bridge only" alternatives. For example, on Genesee Avenue between Decoro Street and Nobel Drive, the projected volume is 40,800 ADT with no project, and 39,800 ADT with the bridge in -- a difference of 1,000 ADT. On Regents Road, the volume between Arriba Street and Nobel Drive is projected to be 13,000 ADT with no project, and 22,800 ADT with the bridge in -- a difference of 9,800 ADT. Thus, of those additional 9,800 ADT drawn to that segment of Regents Road, only 1,000 ADT are drawn from Genesee Avenue. The remaining 8,800 ADT, being North/South-directed trips, are from the freeways (mostly from Interstate 5, which is close to and parallels Regents Road).

The bridge is most effective in relieving Genesee Avenue traffic on the segment between Decoro Street and Governor Drive. But even there, the draw from Genesee Avenue, about 9,500 ADT at best, is significantly smaller than the draw of regional traffic from the freeways - 15,300 ADT. Why should we spend $30 million to take only 9,500 ADT from this segment of Genesee Avenue? Widening Genesee Avenue itself would result in a better level of service than the bridge!
