At the same time, the section of Bird Road from the intersection with Blewett Road north to the intersection with SR-132 was improved to a two-lane, 40-foot wide paved - roadway (two 16-foot travel lanes with 4-foot shoulders). San Joaquin County's current typical section for a rural collector is a 40-foot wide paved roadway. The existing roadway cross section is consistent with current County standards _ Between SR-132 and Blewett Road, Koster Road is a two-lane County rural road with a 20-22 foot paved width with little or no shoulders. San Joaquin County's current typical cross section for a rural road is a _ 32-Foot paved roadway. The existing roadway cross section would be considered nonstandard based on the current County standards. Between Bird Road and Koster Road, Blewett Road is a two-lane County Waal road. Between Koster Road west to the approaches to the Blewett Road over crossing over I-5 and from just to the west of the California Aqueduct bridge to Bird Road, Blewett Road has a 20-22 foot paved width with no shoulders. The existing roadway cross section within these segments would be considered nonstandard based on the - current County rural road standard of 32-foot paved width. The segment of Blewett Road from the approach to the over crossing over I-5 to the west end of the California Aqueduct bridge generally has a Ind Draft DeSilva Gates Quarry Traffic&Circulation Analysis 48 October 1005 Jones&Stokes (R905TIS001/25-4000-01)
