RATING OF CONDITION: Deck 9 - Substructure 9 Superstructure 9 Overall 9 PREVIOUS REPORTS There is a previous bridge report dated June 17, 1966. EXISTING POSTING There is no record of any restrictive posting for load or speed by the Director and there are no limiting signs posted at the bridge site. CONDITION OF STRUCTURE Minor fine transverse cracks in RC curbs over supports. No surfcing on bridge deck. Deck surface has very rough finish. Wire netting for A4 slope is missing. Only timber framing for netting is in place. Wire slope netting for Al slope is in place. - ENCROACHMENTS Railroad signal and power lines run under bridge on each side of B3. Lines are supported on poles running parallel to RR tracks. CAPACITY Bridge is good for legal loads by design and for over- loads shown on Sheet 1 by design calculation check. POSTING RECOIllNDATION None. ?_,ea BERNARD S. LAPEDIS Associate Bridge En ineer FORM HBD-M70A P.E. Lic. No. c-1707 EXPLANATION OF OVERLOAD RATINGS As an example, assume .the rating for a structure is P-7, . G91 0-13. . . . This statement means that the structure has an overload capacity Of a 7-axied . lip" purple truck, a 9-axied "G" green truck, and a.13-axle "0" orange truck. A PURPLE load consists of a single 26 ]d.p axle followed by 48 kip dual axles at 18' centers. . . AGREEN lod.is 0.867 times a PURPLE load.. . . An ORANGE load is 0.667 times a PURPLE load. . • As a further explanation, assume ''a short bridge which physically has room for only a single dual axle. If this structure has the capacity to carry a single dual purple axle without failing, it would be rating P-13 - the maximum purple load. . •.. . . . . . . ... • - On the other hand a long bridge which could physically contain the entire length of a purple load might be rated P-9. In other words, axles were taken off until the structure's capacity was .not exceeded. • The Green and Orange loads are similarly applied to the - structure until it's capacity is attained. . . Of V%4 U.S. DEPARTMENT OF TRANSPORTATION FEDERAL HIGHWAY ADMINISTRATION. WASHINGTON. D.C. 20591 Tide 23—HIGHWAYS Chapter I.—Federal Highway Admin- istration, Department of Transporta- tion PART 25—NATIONAL BRIDGE INSPECTION STANDARDS On September 14. 1970, the Federal Highway Administrator issued 6 notice. Indicating that he was considering Im- plementation of section 28 of the Federal- Aid Highway Act of 1968, 23 U.S.C. 116 (d) by adopting National Bridge Inspec- tion Standards (35 F.R. 14864). The pro- posed standards set forth in that notice were based generally upon the contents of the "Manual for Maintenance Inspec- tion of Bridges 1970" published by the American Association of State Highway Officials. Interested persons were invited to submit comments on the proposed standards. In response to that invitation, 145 comments were filed. Submissions were received from over half the State highway departments. Subdivisions of the States, private organizations, and government officials also made their views known. The comments, together with other available data, have been carefully con- sidered. In general, they indicated that the majority of the Nation's bridge owners will be able satisfactorily to com- ply with the standards as they were proposed. After studying the available informa- tion. the Administrator has decided to Issue the standards substantially as they appeared in the notice. A few changes have been made, principally for the pur- pose of eliminating ambiguous or unclear provisions and In order to strengthen the standards in areas where more stringent requirements appeared necessary. Several comments pointed out that the opening paragraph of the proposal, which contained a definition of the bridges sub- ject to the standards, was somewhat lacking in specificity. The language (now 125.1) has been revised to eliminate any doubt about whether a particular struc- ture is Included among the bridges to which the standards are applicable. The last sentence of the third paragraph In the Inspection procedures section (now RULES AND REGULATIONS § 25.3(c)) has also been reworded In an effort to clarify its intent. The section dealing with freqtmncy of Inspections (5 25.4) has been changed to make It clear that, while each bridge must be inspected at least every 2 years, the depth of each inspection and the frequency of Inspections within that time span are matters which must be resolved by the person In charge of the Inspection program. The provisions of section 3 of the pro- posed standards, dealing with qualifica- tions of personnel, proved to be quite controversial, The Administrator was asked to reduce the level of qualifications to be required. He has declined to do so and has, in fact, made two changes with the objective of Increasing the level of competence which both field inspection supervisors and their direct superiors must possess. Both experience and com-monsense teach that the professional Qualifications of the Individuals in charge of performing Inspections Is a sine qua non of a sound program. All of the pains-taking effort that has gone into develop- ment of the inspection procedures and the reporting and recotdkeeping require- ments Is worthless If the people in charge of performing the Inspections are not fully qualified to do so. A primary ele- ment of the qualifications of supervisory Personnel Is training in the techniques and criteria of Inspection of bridges. Hence, the Administrator has provided that supervisors who do not possess the Qualifications for registration as profes-sional engineers must complete a comprehensive training course based upon the "Bridge Inspector's Training Manual." Many bridge owners who commented on the Inventory provisions of the pro-posed standards argued that they would require collection of data that were not readily available and would therefore require an expenditure of time and ef- fort out of proportion to their value as Part of the bridge Inspection program. In informal discussions with various owners, it was learned that much of the information needed to complete the in- ventory form was already at hand, us- ually in the element of their organiza- tions responsible for planning. There was 7851 a consensus that implementation of the Inventorying requirement should be put off until July 1, 1973. However, the en- actment of section 204 of the Federal Aid Highway Act of 1970 (84 Stat. 1713) Introduced a note of urgency with re- spect to the matter of completing inven- tories of certain bridges. Section 204 au- thorizes a new special bridge replace- ment program, partially funded with Federal-aid highway funds. As a first step in the program, the statute re- quires the Secretary, in consultation with the States, to inventory all bridges on any of the Federal-aid highway systems over waterways and other topographical barriers. In order to bring the new pro- gram into operation as pomptly as pos- sible, the Administrator has adhered to the July 1, 1972, deadline for inventory- ing bridges specified In that statute. The inventory of all other bridges must be completed by July 1, 1973. In consideration of the foregoing, a new Part 25 Is added to Title 23, CPR, Incorporating the National Bridge In- spection Standards and reading as set forth below. The National Bridge Inspection Stand- ards are effective 30 days after the date upop which they are published In the FEDERAL Rzcisrzn. The National Bridge Inspection Stand- ards are Issued under the authority of section 26 of the Federal-Aid Highway Act of 1988, 23 U.S.C. 116(d) and the delegation of authority by the Secre- tary of Transportation In 49 CPa 1.48 (b).

In accord- nuns with Federal-Aid Coding Manual Standards and the AASHO (American Association of State Highway Officials) Highway Definitions Manual, a "bridge" Is defined as a structure including sup- ports erected over a depression or an ob- struction. as water, highway, or railway and having a track or passageway for carrying traffic or other moving loads, and having an opening measured along the center of the roadway of more than 20 feet between undercopings of abut- ments or spring lines of arches, or ex- treme ends of openings for multiple boxes; it may include multiple pipes, where the clear distance between open- ings is less than half of the smaller con- tiguous opening. § 25.3 Inspection procedures. Each highway department shall Include a bridge inspection organization capable of performing inspections and preparing reports and determination of ratings in accordance with the provisions of the AASHO Manual' and the stand- ards contained herein. Bridge inspectors shall meet the minimum qualifications stated in $25.7. (0) Each structure required to be in- spected under the Standards shall be rated as to its safe load carrying capacity In accordance with section 4 of the AASHO Manual. If It is determined un- der this rating procedure that the maxi- mum legal load under State law exceeds the load permitted under the Operating Rating Stress Level, the bridge must be posted in conformity with the AASHO Manual or in accordance with State law. (d) Inspection records and bridge in- ventories shall be prepared and main- tained In accordance with the Standards. § 25.5 Frequency of Inspections. Each bridge Is to be Inspected at regular Intervals not to exceed 2 years In accordance with section 23 of the AASHO Manual. The depth and frequency to which bridges are to be inspected will depend on such factors as age, traffic character- Istics, state of maintenance, and known deficiencies. The evaluation of these fac- The "AASHO Manual" referred to in this part Is the "Manual for Maintenance Inspec-tion of Bridges 1970" published by the Amer-ican Association of State Highway Official,. A copy of the Manual may be examined dur- ing normal business hours at the office of each Division Engineer of the Federal High- way Administration, at the olflce of each Regional Federal Highway Administrator, and at the Washington headquarters of the Federal Highway Administration. The ad- dresses of those document inspection facili-ties are set forth in Appendix D to Part 7 of the regulations of the Office of the Seer.. tory (49 CPA Part 7). In addition, a copy of the Manual may be secured upon payment in advance of a fee of $0.75 by writing to the American Associultion of State Highway Of-ficial., 341 National Press Building, Wash- ington, DO 20004. RULES AND REGULATIONS tore will be the responsibility of the in- dividual in charge of the Inspection program. §25.7 Qualifications of personnel. (a) The individual in charge of the organizational unit that has been dele- gated the responsibilities for bridge in- spection, reporting, and inventory shall possess the following minimum qualifi- cations: Be a registered professional engi- neer; or Be qualified for registration as a professional engineer under the laws of the State; or Have a minimum of 10 years' ex- perience in bridge Inspection assignments In a responsible capacity and have com- pleted a comprehensive training course based on the "Bridge Inspector's Train- ing Manual," which has been developed by a joint Federal-State task force and Is published by the Department of Transportation.' (b) An Individual in charge of a bridge Inspection team shall possess the follow- ing minimum qualifications: Have the qualifications specified in paragraph (a) of this section; or Have a minimum of 5 years' ex- perience in bridge inspection assignments In a responsible capacity and have corn- pletéd a comprehensh'e training course based on the "Bridge Inspector's Train-ing Manual," which has been developed by a joint Federal-State task force and Is published by the Department of Transportation. § 25.9 Inspection report. The findings and results of bridge in- sections shall be recorded on standard forms. The data required to complete the forms and the functions which must be performed to compile the data- are contained in section 3 of the AASHO Manual. § 25.11 Inventory. Each State shall prepare and maintain an inventory of all bridge structures subject to the Standards. If a state. wishes to expand the inventory to include structures not subject to the Standards, the bridges which are sub- ject to the Standards shall be separately Identifiable in the records. Under the Standards certain structure inventory and appraisal data must be collected and retained within the various departments of the State organ!- station for collection by the Federal High- way Administration as needed. A tabula- tion of these required data is contained in the structure inventory and appraisal sheet distributed by the Federal High- way Administration along with its Cod- ing Guide in April of 1971.
