If any of the facilities heretofore or hereafter erected, constructed, installed or maintained by the grantee pursuant to the franchise on, along, upon, over, in, under or across any highway are located in a manner which prevents or interferes with the change of grade, traffic needs, operation, maintenance, improvement, repair, construction, reconstruction, widening, alteration or relocation of the highway, the grantee shall relocate permanently or temporarily any such facility at no expense to the city or public entity upon receipt of a written request from the public works director to do so, and shall commence such work on or before the date specified in such written request, which date shall be not less than thirty (30) days from receipt of such written request, and thereafter diligently prosecute such work to completion; provided, however, if such city streets be subsequently constituted a state highway, thereafter and so long as such highway remains a state highway, no such change of location shall be required for a temporary purpose.
