A complete routine inspection was <br />performed. <br />WATERWAY <br />A channel cross section was spot checked during this inspection. The measurement at Bent 2 is two feet lower than the last routine <br />inspection on 09/02/2021. There is broken concrete/rip rap at the bents so the measurement location may not be exact. <br />This structure has no history of significant scour or hydraulic problems. The County placed broken concrete rock slope protection (RSP) <br />at both abutments after the 2011 inspection. The County performed a scour evaluation on 7/14/2021 and their report is on file. <br />The hydraulics report dated 08/29/2001 determined that this structure is scour critical. The channel bed material is highly erodible and the <br />calculated scour elevation is lower than the allowable scour elevation. A Bridge Scour Evaluation - Plan of Action dated 11/4/2005 is on <br />file. <br />RECOMMENDATIONS <br />Monitor the structure for scour related problems during flood events. <br />INSPECTION COMMENTARY <br />TYPE OF MEMBRANE <br />TYPE OF DECK PROTECTION <br />DECK STRUCTURE TYPE <br />TYPE OF WEARING SURFACE <br />WEARING SURFACE / PROTECTIVE SYSTEM <br />1882AVERAGE DAILY TRAFFIC <br />2011 YEAR OF ADT <br />5 KMBYPASS, DETOUR LENGTH <br />20 %(109) TRUCK ADT % <br />1572FUTURE ADT <br />2038 YEAR OF FUTURE ADT <br />HISTORICAL SIGNIFICANCE 5: NOT ELIGIBLE FOR NRHP <br />6-BITUMINOUS <br />0-NONE <br />0-NONE <br />1-CIP CONCRETE <br />DECK STRUCTURE INFORMATION <br />9.9 M <br />9.7 M <br />DECK AND ROADWAY <br />LANES 2 <br />35 <br />0-NOT ON NHS <br />PARALLEL STRUCTURE <br />TEMPORARY STRUCTURE <br />DEFENSE HIGHWAY <br />FUNCTIONAL CLASS <br />SPEED <br />NATIONAL HIGHWAY SYSTEM <br />TOLL <br />DIRECTION OF TRAFFIC <br />DESIGNATED NATIONAL NETWORK <br />TYPE OF SERVICE <br />FEDERAL LANDS HWY <br />8 EQUAL DESIRABLE CRITAPPR ROADWAY ALIGN <br />5 ABOVE TOLERABLEDECK GEOMETRY <br />7.6 MAPPROACH RDWY WIDTH <br />BRIDGE MEDIAN <br />LEFT 0.0 M RIGHT 0.0 MCURB OR SIDEWALK <br />TOTAL WIDTH <br />NET WIDTH <br />9.7 MINVENTORY ROUTE TOTAL HORIZ CLEAR <br />99.99 MINVENTORY ROUTE MIN VERT CLEAR <br />3-ON FREE ROAD <br />09-LOCAL RURAL <br />0-NOT STRAHNET <br />N-NONE EXISTS <br />2-2 WAY <br />0-NOT APPLICABLE <br />0-NOT ON NET <br />0 NO MEDIAN <br />1-HIGHWAY <br />DECK ROADWAY/OPERATIONAL INFORMATIONDECK GEOMETRY <br />0.3 ft br, 32.1 ft, 0.3 ft br <br />DECK CROSS SECTION <br />LRS INVENTORY RTE & SUBRTE <br />BASE HIGHWAY NETWORK 0-NOT ON NET <br />- NOT APPLICABLE FOR THIS BRIDGE. <br />.5 inchesOVERLAY THICKNESS (inches) <br />N/A <br />(51) <br />(52) <br />(50) <br />(32) <br />(33) <br />(107) <br />(108) <br />A) <br />B) <br />C) <br />(29) <br />(30) <br />(19) <br />(114) <br />(115) <br />(37) <br />(42a) <br />(12) <br />(13) <br />(104) <br />(26) <br />(100) <br />(101) <br />(102) <br />(10) <br />(47) <br />(68) <br />(72) <br />(105) <br />(110) <br />(20) <br />(28a) <br />(103) <br />CONDITION INFORMATION <br />25.9 MLENGTH (49) <br />Element DescriptionElem <br />No. <br />Env Total <br />Qty <br />Units <br />CS 1 CS 2 CS 3 CS 4 <br />Qty in each Condition State <br />38 Slab-RC <br />Delamination/Spall/Patched Area <br />Cracking (RC and Other) <br />2 <br />2 <br />2 <br />256 <br />1 <br />4 <br />sq.m <br />each <br />each <br /> 251 <br /> 0 <br /> 0 <br /> 5 <br /> 1 <br /> 4 <br /> 0 <br /> 0 <br /> 0 <br /> 0 <br /> 0 <br /> 0 <br />DECK ELEMENT INSPECTION RATINGS AND NOTES <br />Defect/ <br />Prot <br />1080 <br />1130 <br />Defect <br />(58) 7DECK RATING = <br />SPECIAL INSPECTION INFORMATION
