The Honduras road may have been organized by McConnico, but George Mansfield was definitely involved. It's discussed on pp. 84-85 of Donald Ball's book, George Mansfield and the Billerica & Bedford Railroad. According to Ball, the line was supposed to be 115 miles long, linking the port of Trujillo with Puerto Cortez. Mansfield traveled to Honduras with McConnico in 1888 to plan construction, but the financing fell through and it was never built.
