There is a Dominion power line project that involves burying 230KV transmission lines from the Idylwood substation out to Tyson's substation. Portion of this will run along the WOD that parallels I-66 and out to Gallows road. Not sure what construction impact this will have on the WOD, if any as Dominion plans to use horizontal directional drilling on this section, below is the link for this project:
