At the time of this inspection, there was approximately 5 <br />feet of water flowing under Spans 10 to 12. Abutments and piers were dry except Piers 11 and 12. Piers 11 and 12 were partially <br />submerged in approximately 5 feet of water and were inspected by the Underwater Inspection team. This routine inspection was limited <br />to the deck, soffit, and columns above the water line that could be seen from the river banks. A complete routine inspection was <br />performed on all visible elements. <br />This structure is currently in the SM&I Underwater inventory for inspecting substructure elements submerged in deep water on 60 month <br />cycle. The last Underwater Inspection (UWI) was performed on 07/12/2021. Refer to the 07/12/2021 UWI report for details. <br />SAFE LOAD CAPACITY <br />The load rating for this structure is being reviewed by SM&I Load Ratings Branch under Work Request 12210. An updated Load Rating <br />Summary will be archived when this review is complete. The current rating is based on BDS computer output dated 04/21/1980. <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 />1205AVERAGE DAILY TRAFFIC <br />2017 YEAR OF ADT <br />16 KMBYPASS, DETOUR LENGTH <br />12 %(109) TRUCK ADT % <br />927FUTURE ADT <br />2045YEAR OF FUTURE ADT <br />HISTORICAL SIGNIFICANCE 5: NOT ELIGIBLE FOR NRHP <br />0-NONE <br />0-NONE <br />0-NONE <br />1-CIP CONCRETE <br />DECK STRUCTURE INFORMATION <br />8.7 M <br />8.5 M <br />DECK AND ROADWAY <br />LANES 2 <br />55 <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 />7.9 MAPPROACH RDWY WIDTH <br />BRIDGE MEDIAN <br />LEFT 0.0 M RIGHT 0.0 MCURB OR SIDEWALK <br />TOTAL WIDTH <br />NET WIDTH <br />8.5 MINVENTORY ROUTE TOTAL HORIZ CLEAR <br />99.99 MINVENTORY ROUTE MIN VERT CLEAR <br />3-ON FREE ROAD <br />08-MINOR COLLECTOR 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, 28.0 ft, 0.3 ft br <br />DECK CROSS SECTION <br />LRS INVENTORY RTE & SUBRTE <br />BASE HIGHWAY NETWORK 0-NOT ON NET <br />1 - FreshWater TypeB - Routine UWDive Type <br />Next UWI 07/12/2026UWI Frequency months 60UWI Required Y Last UWI 07/12/2021 <br />- NOT APPLICABLE FOR THIS BRIDGE. <br />0 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 />205.6 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 />16 Top Flange-RC <br />Exposed Rebar (PS Conc./RC) <br />2 <br />2 <br />372 <br />2 <br />sq.m <br />each <br /> 370 <br /> 0 <br /> 2 <br /> 2 <br /> 0 <br /> 0 <br /> 0 <br /> 0 <br />DECK ELEMENT INSPECTION RATINGS AND NOTES <br />Defect/ <br />Prot <br />1090 <br />Defect <br />(58) 7DECK RATING = <br />SPECIAL INSPECTION INFORMATION
