Indian River County, Amendment No. 2 <br /> 66" Avenue/ County Road 510 Roadway <br /> Widening <br /> • Provide boring profile reports. <br /> • Recommendations for additional study, if appropriate <br /> Deliverables shall consist of six (6) copies of the Geotechnical Report with soil <br /> boring records, test results, photographs and similar data, summary of testing <br /> program and recommendations ; soil boring plan for incorporation into the <br /> roadway plan package. <br /> K. Structure Plans <br /> The ENGINEER shall prepare preliminary and final bridge plans for the <br /> demolition and replacement of bridges on 61 " Street, 65th Street and 69th Street <br /> over the Lateral ` A ' Canal as detailed below : <br /> Bridge Section <br /> No . 884038 over Lateral ` A' Canal 3 -Lane (expandable to 5 -Lane) <br /> No . 880049 over Lateral ` A' Canal 3 -Lane (expandable to 5 -Lane) <br /> No . 884039 over Lateral ` A' Canal 3 -Lane (expandable to 5 -Lane) <br /> 1 . The proposed typical section will consist of three lanes, 8 ft. sidewalk and <br /> 4 ft. paved shoulder on one side, 8 ft. shoulder on opposing side and utility <br /> shelves on both sides of each bridge, with an estimated overall width of <br /> 66 "-6" . <br /> 2 . Due to the geometric similarity between the three bridge replacement <br /> locations, a common bridge length will be utilized for each replacement. <br /> The bridges are assumed to be no more than two spans, with a maximum <br /> span length of about 40 feet. <br /> 3 . Bridge plan geometries and wingwall configurations will minimize the <br /> encroachment of the bridge ends into adjacent intersections and <br /> driveways . Wingwalls will also be set to allow for utility burial at the <br /> bridge ends. <br /> 4. Slope protection, rip-rap and/or sheetpiles will be used at the bridge <br /> abutments to stabilize the canal banks in the vicinity of the bridges. <br /> 5 . It is anticipated that the COUNTY will allow road closures at all three <br /> bridge replacement locations such that phased construction will not be <br /> required. <br /> 6 . Utility coordination will be performed in order to evaluate existing utilities <br /> and accommodate utility crossings on the proposed bridges . <br /> Page 7 of 11 <br />
