Current through Register Vol. 56, No. 18, September 16, 2024

(a) Acceptable utility installations are those that will occupy a position beneath the structure's floor, between the outer girders or beams, or within a cell and at an elevation above the low point of the super-structure steel or masonry. The following restrictions shall apply:

1. No utilities shall be placed in the deck, sidewalk, or parapet of a bridge.

2. No utility shall be placed outside the parapet where people may walk on it.

3. The Department prohibits placement of gas, water, sewer mains, or other hazardous utility facilities inside box beams or other enclosed structural elements. Due to homeland security and safety concerns, the Department may prohibit placement of electric and communication lines on certain bridge types. For bridge replacement projects, the Department shall take into consideration utilities currently attached to the bridge in the evaluation and selection of bridge types.

4. Connections for utility supports to pre-stressed concrete beams shall be made to inserts cast in the beams. Drilling into pre-stressed concrete beams shall not be permitted.

5. Utility facilities shall not be supported by a system which requires inserts in the concrete deck slab.

6. Conglomeration of utilities in the same bay should be avoided in order to facilitate inspection and painting of the structure.

7. Unless appropriate devices are provided at bridge deck joints to accommodate movement, bridge-mounted utilities shall not be rigidly attached to the structure.

8. Galvanized structural steel shall be utilized for supports where structural elements cannot be utilized to carry loads.

9. Welding to structural steel beams shall not be permitted.

10. Ducts shall be provided for electrical and communication cables.

11. Pipes carrying liquids under pressure shall be sleeved within 10 feet of abutments, walls, and piers.

12. Pipes installed through abutment backwalls shall be placed in steel sleeves, coated with a corrosion inhibiting material, and set in non-shrink grout with the opening between the pipe and the sleeve sealed to prevent leakage through the backwall.

(b) The provisions of N.J.A.C. 16:25-8.1(c), 8.6, and 8.7(a)5 shall be followed for pipeline attachments to bridge structures, except that sleeves shall be required only through abutment backwalls.

(c) Since a casing is not typically provided for a pipeline attachment to a bridge, additional protective measures shall be taken, including employing a higher factor of safety in the design, construction, and testing of the pipeline.

(d) Where a pipeline attachment to a bridge is in a casing, the casing shall be effectively opened or vented at each end to prevent possible buildup of pressure and to detect leakage of gases or fluids.

(e) For pipelines under pressure, shut-off valves, preferably automatic, shall be provided on both sides of a bridge.

(f) Communication and electric power line attachments shall be suitably insulated, grounded, and carried in protective conduit or pipe from the point of exit from the ground to re-entry. The conduit shall be carried to a manhole located beyond the backwall of the structure. Carrier pipe and casing shall be suitably insulated from electric power line attachments.

(g) Guy wires supporting any utility facility shall not be attached to a bridge structure.

(h) Cell phone or other type antennas shall not be mounted from or on any bridge or sign supported structure
