Conn. Gen. Stat. § 13b-282
When any highway passes over or under a railroad, if the convenience and necessity of the public require a change in such highway, the town, city or borough in which such highway is located may bring a petition to the Commissioner of Transportation in the manner prescribed in section 13b-270, and, after the notice prescribed by said section, said commissioner shall proceed to a hearing on such matter and may make such order as the commissioner deems necessary for the convenience and necessity of the public or the safe and suitable operation of the railroad. For the purposes of this section, said commissioner shall have and exercise all powers of said commissioner concerning the removal of grade crossings, and land may be taken. The party upon whom is imposed, by such order, the duty of making such changes in such highway may use the material and abutments of any existing bridge in the old highway in the construction of a bridge in the substituted or changed highway. The expense of any changes ordered as hereinbefore provided shall be apportioned, among the railroad company and the town, city or borough interested therein, in such manner as the commissioner deems equitable; but in no case shall an amount in excess of one-half of the expense of such alteration, including land damages or special damages, be assessed upon any such town, city or borough.
