If the defective highway or bridge is on the line between two towns, and both towns are liable to keep the highway or bridge in repair, notice shall be given to both towns, and they shall be jointly liable the same as if the highway or bridge were in one town. Where the highway or bridge complained of is located on the line between two counties, all questions arising under the provisions of this chapter may be tried in the county where the complaint is made.
