The abutments were <br />outside of the water. The inspection was limited to the deck and portions of the superstructure and substructure above the water line and <br />portions of the bridge visible from the canal banks. A return visit will be scheduled when the canal is dewatered. <br />The submerged portions of Piers 2 and 3 were inspected by the Caltrans Underwater Inspection Team. The most recent underwater <br />investigation was performed on 05/28/2020. All identified defects from that inspection have been incorporated into the condition states of <br />the respective elements and have been described in the element or defect notes. Refer to the 05/28/2020 underwater inspection report <br />for further detail. <br />DECK AND ROADWAY <br />There are pattern cracks up to 2 inches wide in the AC approach within 5 feet of the bridge deck at Abutment 1. (See Photo 5 dated <br />06/08/2022). This condition has been previously reported and no significant changes were noted. <br />SAFE LOAD CAPACITY <br />The load rating for this structure is being reviewed by SMI Ratings Branch under Work Request #10021. An updated Structure Rating <br />Summary Sheet will be archived when this review is complete. The current rating is based on BDS computer output dated 01/07/1980. <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 />617AVERAGE DAILY TRAFFIC <br />2013 YEAR OF ADT <br />13 KMBYPASS, DETOUR LENGTH <br />10 %(109) TRUCK ADT % <br />2173FUTURE ADT <br />2040YEAR 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 />12.4 M <br />12.2 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 />8 DESIRABLE CRITERIADECK GEOMETRY <br />12.2 MAPPROACH RDWY WIDTH <br />BRIDGE MEDIAN <br />LEFT 0.0 M RIGHT 0.0 MCURB OR SIDEWALK <br />TOTAL WIDTH <br />NET WIDTH <br />12.2 MINVENTORY ROUTE TOTAL HORIZ CLEAR <br />99.99 MINVENTORY ROUTE MIN VERT CLEAR <br />3-ON FREE ROAD <br />07-MAJOR 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, 40.0 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 05/28/2026UWI Frequency months 72UWI Required Y Last UWI 05/28/2020 <br />- NOT APPLICABLE FOR THIS BRIDGE. <br />2 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 />35.1 MLENGTH (49) <br />DECK ELEMENT INSPECTION RATINGS AND NOTES (58) DECK RATING = <br />SPECIAL INSPECTION INFORMATION
