Conn. Agencies Regs. § 13b-17-17
The requirements for the new installation of utilities on any State or interstate highway are contained in the current edition of the Department of Transportation publication, "A Policy on the Accommodation of Utilities on Highway Rights of Way" and the AASHTO publication, "A Policy on the Accommodation of Utilities on Freeway Rights of Way."
The granting of permits to install public utility and other structures does not diminish or waive the jurisdiction of the Transportation Commissioner over State highways. If, in the opinion of the Transportation Commissioner, it becomes necessary at any time to remove or relocate any of the structures or fixtures installed under a permit, the removal or relocation, upon notification by the Commissioner or an authorized agent, shall be made immediately by the owner thereof, in accordance with the Connecticut General Statutes, as revised.
