Section 16:25-9.5 - Trenchless construction

(a) Acceptable techniques for installing underground electric power and communication lines under a highway without disturbing the surface are subject to specific site conditions including, but not limited to, driving, coring, boring, horizontal directional drilling, jacking, or pushing of pipe as conduit.

(b) The design and trenchless construction of underground electric power and communication lines under highways shall include the following:

1. The trenchless construction shall extend a suitable distance beyond the slope or ditch lines. Where appropriate, the trenchless construction shall extend to the access control lines, to the outside of frontage roads, or to an indicated line that allows for future widening of the highway without the need for any utility adjustment;

2. The portal limits of crossings shall be located beyond the surfaced areas of the highway to avoid impairing the roadway during installation; and

3. The Department will establish, on a case-by-case basis, the need to grout the voids outside the carrier.

(c) When trenchless installation is proposed by the utility, the utility shall furnish the Department with information regarding the construction methods, controls, and monitoring to be used.
