Section 17 AAC 15.231 - Highway structures(a) The department will, in its discretion, permit the attachment of utility facilities to a highway structure. The chief bridge engineer is responsible for exercising this discretion to grant permission.(b) Attachments to a bridge must be located beneath the bridge structure's floor, between outer beams or within a cell of a box beam, and must be located above the lowest steel or masonry members. If the utility can demonstrate to the department's satisfaction that a location requirement is not feasible and that attachment at an alternate location will not adversely affect the design, construction, maintenance, safety, or operation of the structure, the department will, in its discretion, permit the attachment at an alternate location.(c) Communication and electric power cables or conductors must be encased in an approved conduit supported by suitable hangers or brackets and must have appropriate expansion devices. Acceptable alternate methods of installation for communication cable will, in the department's discretion, be permitted.(d) Where required by special provisions in the utility permit, pipelines carrying flammable, corrosive, or other hazardous materials must be encased and have sufficient venting. The facility must be provided with automatic shut-off valves or other safety devices at or near each end of the structure as specified in the special provisions of the permit. The department will, in its discretion, require cathodic protection.(e) A utility shall restore or repair any portion of a bridge or highway that is damaged by the installation or the operation of a facility attached to a highway bridge structure or its appurtenances.(f) The department will, in its discretion, require a utility to reimburse the department for any or all costs incurred by the department for engineering, design changes, or modifications of the highway bridge structure that are necessary to accommodate attachment of the utility facility.Eff. 5/23/82, Register 82Authority:AS 19.05.020
