y <br /> f. yK <br /> PROJECT DESCRIPTION <br /> The proposed Interstate 5/Bird Road Interchange and Road Specific Plan, as shown on the attached figure, is <br /> consistent with both the approved San Joaquin County General Plan Amendment and the Caltrans Project Study <br /> Report (PSR). Therefore, the proposed interchange; roadway alignments, and right of way requirements <br /> contained within the Interstate 5/Bird Road Interchange and Road Specific Plan have been determined after <br /> an in-depth study and evaluation of the various alternatives. A brief description of the planned interchange <br /> and roadway extension design is included in the foIIowing paragraphs. The interim and ultimate designs are <br /> presented in Figures 2 and 3. The proposed plan line and required right-of-way requirements for these designs <br /> are detailed in the accompanying plan set. <br /> The planned new Interstate 5/13ird Road Interchange consists of a modified par-'clo design, including only a <br /> single eastbound to northbound loop on-ramp rather than two internal loop on-ramps. The new interchange '. <br /> will be approximately 1500 meters north of the Interstate 5$0/Interstate 5 separation and just south of a <br /> California Aqueduct crossing of Interstate 5. The new Bird Road extension will be constructed to intersect <br /> with the interchange in order to provide local access to the new interchange. The interchange extends from <br /> just south of Hospital Creek north to the California Aqueduct. New bridges will be required at the northbound <br /> off-ramp and southbound on-ramp over Hospital Creek and for the county road over the Interstate. <br /> The new Bird Road extension will realign the existing Bird Road just north of the existing high pressure gas <br /> pipelines, traverse southeasterly across and create an interchange with Interstate 5 and then continue to Gaffery <br /> Road in Stanislaus County. In addition to the bridge crossing of Interstate 5, the new extension will also <br /> require improvements to both crossings of the California Aqueduct in San Joaquin County and Delta Mendota <br /> Canal within Stanislaus County as well as require crossing of an existing watercourse, floodplain and floodway <br /> associated with Hospital Creek. Box culverts will be used in crossing this area. The extension in its entirety <br /> will be approximately 3.3 miles in length. <br /> The remaining existing Bird Road south of the new Bird Road extension will be realigned to "T" into the new <br /> county road and will require a new crossing of the existing pipelines. On the southeasterly end, the Bird Road <br /> extension will be aligned to flow into the existing Gaffery Road to the east across both the California Aqueduct <br /> and Delta Mendota Canal. At the juncture with Gaffery Road, the westerly alignment of the existing Gaffery <br /> Road will also require realignment to "T" into the newly realigned Bird Road extension. <br /> Included in this Interstate 5/Bird Road Interchange and Road Specific Plan project will be the rehabilitation <br /> of Gaffery Road from the intersection with the existing Gaffery Road to the SanJoaquin County line <br /> Rehabilitation of this segment of roadway will include replacement of the approach guardrails at the Gaffery ! <br /> Road bridge over the California Aqueduct <br /> M <br /> Project Description Page 4 <br /> Interstate 51Bird Road Interchange and Road Specific Plan <br /> M <br />
