1、155 Federal Highway Administration, DOT Pt. 625 copy of a suitable map or maps identi-fied by the Federal-aid project number, with the facilities to be relinquished and the date of such relinquishment ac-tion clearly delineated thereon. (2) If it is found at any time after re-linquishment that a rel
2、inquished facil-ity is in fact required for the safe and proper operation of the Federal-aid highway, the State shall take imme-diate action to restore such facility to its jurisdiction without cost to Fed-eral-aid highway funds. (3) If it is found at any time that a relinquished frontage road or po
3、rtion thereof or any part of the right-of-way therefor has been abandoned by local governmental authority and a showing cannot be made that such abandoned facility is no longer required as a pub-lic road, it is to be understood that the Federal Highway Administrator may cause to be withheld from Fed
4、eral-aid highway funds due to the State an amount equal to the Federal-aid par-ticipation in the abandoned facility. (4) In no case shall any relinquish-ment include any portion of the right- of-way within the access control lines as shown on the plans for a Federal-aid project approved by the FHWA,
5、 with-out the prior approval of the Federal Highway Administrator. (5) There cannot be additional Fed-eral-aid participation in future con-struction or reconstruction on any re-linquished off the Federal-aid sys-tem facility unless the underlying reason for such future work is caused by future impro
6、vement of the associ-ated Federal-aid highway. (g) In the event that a State desires to apply for approval by the Federal Highway Administrator for the relin-quishment of a facility such as de-scribed in paragraph (d) (1) and (2) of this section, the facts pertinent to such proposal are to be presen
7、ted to the di-vision engineer of the FHWA. The divi-sion engineer shall have appropriate re-view made of such presentation and forward the material presented by the State together with his findings there-on through the Regional Federal High-way Administrator for consideration by the Federal Highway
8、Administrator and determination of action to be taken. (h) No change may be made in con-trol of access, without the joint deter-mination and approval of the SHA and FHWA. This would not prevent the re-linquishment of title, without prior ap-proval of the FHWA, of a segment of the right-of-way provid
9、ed there is an abandonment of a section of highway inclusive of such segment. (i) Relinquishments must be justified by the States finding concurred in by the FHWA, that: (1) The subject land will not be need-ed for Federal-aid highway purposes in the foreseeable future; (2) That the right-of-way bei
10、ng re-tained is adequate under present day standards for the facility involved; (3) That the release will not ad-versely affect the Federal-aid highway facility or the traffic thereon; (4) That the lands to be relinquished are not suitable for retention in order to restore, preserve, or improve the
11、scenic beauty adjacent to the highway consonant with the intent of 23 U.S.C. 319 and Pub. L. 89285, Title III, sec-tions 302305 (Highway Beautification Act of 1965). (j) If a relinquishment is to a Fed-eral, State, or local government agency for highway purposes, there need not be a charge to the sa
12、id agency, nor in such event any credit to Federal funds. If for any reason there is a charge, the STD may retain the Federal share of the proceeds if used for projects eligi-ble under title 23 of the United States Code. 39 FR 33311, Sept. 17, 1974, as amended at 64 FR 71289, Dec. 21, 1999; 73 FR 77

15、11 Edition) 625.1 625.1 Purpose. To designate those standards, poli-cies, and standard specifications that are acceptable to the Federal Highway Administration (FHWA) for application in the geometric and structural design of highways. 625.2 Policy. (a) Plans and specifications for pro-posed National
16、 Highway System (NHS) projects shall provide for a facility that will (1) Adequately serve the existing and planned future traffic of the highway in a manner that is conducive to safe-ty, durability, and economy of mainte-nance; and (2) Be designed and constructed in ac-cordance with criteria best s
17、uited to accomplish the objectives described in paragraph (a)(1) of this section and to conform to the particular needs of each locality. (b) Resurfacing, restoration, and re-habilitation (RRR) projects, other than those on the Interstate system and other freeways, shall be constructed in accordance
18、 with standards which pre-serve and extend the service life of highways and enhance highway safety. Resurfacing, restoration, and rehabili-tation work includes placement of ad-ditional surface material and/or other work necessary to return an existing roadway, including shoulders, bridges, the roads
19、ide, and appurtenances to a condition of structural or functional adequacy. (c) An important goal of the FHWA is to provide the highest practical and feasible level of safety for people and property associated with the Nations highway transportation systems and to reduce highway hazards and the resu
20、lt-ing number and severity of accidents on all the Nations highways. 625.3 Application. (a) Applicable Standards. (1) Design and construction standards for new construction, reconstruction, resur-facing (except for maintenance resur-facing), restoration, or rehabilitation of a highway on the NHS (ot
21、her than a highway also on the Interstate System or other freeway) shall be those ap-proved by the Secretary in cooperation with the State highway departments. These standards may take into ac-count, in addition to the criteria de-scribed in 625.2(a), the following: (i) The constructed and natural e
22、nvi-ronment of the area; (ii) The environmental, scenic, aes-thetic, historic, community, and pres-ervation impacts of the activity; and (iii) Access for other modes of trans-portation. (2) Federal-aid projects not on the NHS are to be designed, constructed, operated, and maintained in accord-ance w
23、ith State laws, regulations, di-rectives, safety standards, design standards, and construction standards. (b) The standards, policies, and standard specifications cited in 625.4 of this part contain specific criteria and controls for the design of NHS projects. Deviations from specific min-imum valu
24、es therein are to be handled in accordance with procedures in para-graph (f) of this section. If there is a conflict between criteria in the docu-ments enumerated in 625.4 of this part, the latest listed standard, policy, or standard specification will govern. (c) Application of FHWA regulations, al
25、though cited in 625.4 of this part as standards, policies, and standard speci-fications, shall be as set forth therein. (d) This regulation establishes Fed-eral standards for work on the NHS re-gardless of funding source. (e) The Division Administrator shall determine the applicability of the roadwa
26、y geometric design standards to traffic engineering, safety, and preven-tive maintenance projects which in-clude very minor or no roadway work. Formal findings of applicability are ex-pected only as needed to resolve con-troversies. (f) Exceptions. (1) Approval within the delegated authority provide
27、d by FHWA Order M1100.1A may be given on a project basis to designs which do not conform to the minimum criteria as set forth in the standards, policies, and standard specifications for: (i) Experimental features on projects; and (ii) Projects where conditions war-rant that exceptions be made. (2) T
28、he determination to approve a project design that does not conform to the minimum criteria is to be made only after due consideration is given to VerDate Mar2010 09:39 May 11, 2011 Jkt 223076 PO 00000 Frm 00166 Fmt 8010 Sfmt 8010 Y:SGML223076.XXX 223076wwoods2 on DSK1DXX6B1PROD with CFRProvided by I
