In 1859, the settlement, having grown to nearly 3,000 and encompassing about in area, was incorporated as a city. The boundaries of the original city were Douglas Avenue to the north, Wood and Regent streets to the east, Mount Hope Avenue to the south, and Jenison Avenue to the west. These boundaries would remain until 1916. Lansing began to grow steadily over the next two decades with the completion of the railroads through the city, a plank road, and the completion of the current capitol building in 1878.
