As more settlers arrived in the area, further transportation infrastructure was developed. Roads such as the Barlow Road, Canyon Road, and the Applegate Trail were created and small bridges built. Ferries also began to appear in the 1840s at many river crossings in the region. As the population grew, steamboats began regular service on the rivers, and later railroads were developed. The Oregon Steam Navigation Company and other smaller carriers developed transportation networks. The first railroad came in 1858 with the Cascade Railroad Company operating a line in the Columbia River Gorge, followed by the Oregon and California Railroad and eventually connections to the transcontinental rail lines in 1883.
